본 발명은 세포에서 단백질의 수모화(sumoylation)를 실시간으로 분석하는 방법에 관한 것으로, 더욱 상세하게는 이분자 형광 상보 (bimolecular fluorescence complementation) 기법을 이용하여 세포 내 수모화를 분석하는 방법에 관한 것이다. The present invention relates to a method for analyzing protein sumoylation in real time in a cell, and more particularly, to a method for analyzing intracellular hydration using a bimolecular fluorescence complementation technique.

생명체는 단백질이 유전자로부터 전사, 번역된 후 단백질 수식(post-translational modification) 과정을 통하여 단백질의 기능을 조절한다. 현재까지 인산화(phosphorylation), 유비퀴틴화(ubiquitylation), 아세틸화(acetylation), 메틸화(methylation) 등의 다양한 단백질 수식 과정이 알려져 있는데, 이러한 과정들은 적은 에너지 소모로도 단백질의 세포 내 양 또는 위치 등 단백질의 성질을 바꾸어 생명체의 성장과 발달에 중요한 역할을 한다고 보고되었다. 최근에는 다양한 연구들을 통해 단백질 수식 과정으로 유비퀴틴 유사 단백질(ubiquitin-like protein; Ubls)들이 밝혀지고 있고, 이러한 수식 과정을 통해 세포는 세포 주기 조절, 단백질 분해, 단백질의 세포 내 위치 조절, 세포 크기 조절 등의 다양한 단백 질의 기능을 조절한다고 알려지고 있다(Li et al., Nature 1999, 398:246-251; Goehring et al., Mol. Biol. Cell. 2003, 14:4329-4341; Laplaza et al., Biochem. J. 2004, 377:459-467). 특히, 최근에 여러 유비퀴틴 유사 단백질들 중 수모(small ubiquitin-related modifier; SUMO) 단백질이 여러 생명체에서 가장 많이 연구되고 있고 중요한 역할을 한다고 알려지고 있다(Johnson, Annu. Rev. Biochem. 2004, 73:355-382).Living organisms regulate protein function through protein post-translational modification after proteins are transcribed and translated from genes. To date, various protein modification processes are known, such as phosphorylation, ubiquitylation, acetylation, and methylation. These processes are known to require protein consumption, such as intracellular amounts or locations of proteins, with low energy consumption. It has been reported that it plays an important role in the growth and development of life by changing the nature of. Recently, various studies have revealed ubiquitin-like proteins (Ubls) as a protein modification process. Through this modification process, cells regulate cell cycle, protein degradation, protein positioning, and cell size. It is known to regulate the function of various protein quality, such as (Li et al., Nature 1999, 398: 246-251; Goehring et al., Mol. Biol. Cell. 2003, 14: 4329-4341; Laplaza et al. , Biochem. J. 2004, 377: 459-467). In particular, the small ubiquitin-related modifier (SUMO) protein, among other ubiquitin-like proteins, has recently been known to be the most studied and important role in many organisms (Johnson, Annu. Rev. Biochem. 2004, 73: 355-382).

수모는 약 15 kDa 정도의 단백질로 100여 개의 아미노산으로 구성되어 있어 구조적으로도 유비퀴틴과 유사하다. 척추동물에서는 네 종류의 수모 단백질들(SUMO-1, 2, 3, 4)이 발견된 반면 효모에서는 한 종류의 수모 단백질(Smt3)이 발견되었는데 이는 척추 동물에서의 SUMO1과 유사하다고 밝혀져 있다. 수모 단백질은 유비퀴틴 단백질과 같이 기질 단백질의 라이신 잔기에 공유결합한다. 하지만 단백질의 유비퀴틴화는 단백질을 분해시키는 작용으로 잘 알려져 있지만, 단백질의 수모화는 주위 환경에 따라 단백질의 분해뿐만 아니라, 단백질의 기능을 변화시킬 것으로 예상되고 있다(Johnson, J. Biol. Chem. 1997, 272:26799-26802; Johnson, J. Cell Biol. 1999, 147:981-994). 따라서 세포 내 단백질의 기능을 유추하는 데 있어 단백질 수모화 분석이 필수적이라 할 수 있으며, 최근에 이에 대한 연구들이 활발히 진행되고 있다. The hair is about 15 kDa protein and consists of about 100 amino acids, so it is similar in structure to ubiquitin. In vertebrates, four types of hair protein (SUMO-1, 2, 3, 4) were found, while in yeast, one type of hair protein (Smt3) was found, similar to SUMO1 in vertebrates. The hairy protein covalently binds to lysine residues of the matrix protein, such as the ubiquitin protein. However, while ubiquitination of proteins is well known for their ability to degrade proteins, hydrocyclization of proteins is expected to alter the function of proteins as well as the degradation of proteins depending on the environment (Johnson, J. Biol. Chem. 1997, 272: 26799-26802; Johnson, J. Cell Biol. 1999, 147: 981-994). Therefore, in order to infer the function of the protein in the cell can be said to be essential protein analysis, and research on this has been actively conducted recently.

단백질의 수모화 현상에 대한 관심이 증가함에 따라 이를 분석하기 위한 여 러 연구가 진행되고 있으며, 현재 효모에서는 총 6000여 개의 단백질 중 300여 개의 단백질이 수모화 된다고 밝혀져 있다. 효모 단백질의 수모화 연구에 사용되고 있는 방법은 크게 면역침강법(immunoprecipitation)을 이용한 후 질량분석법으로 분석하는 방법과 연속 친화 정제 표지(tandem affinity purification tag)가 부착된 단백질을 이용하여 웨스턴 블롯(Western blot)으로 분석하는 방법으로 나눌 수 있다. As interest in protein hydration increases, several studies are being conducted to analyze it. Currently, about 300 proteins out of a total of 6,000 proteins are found to be hydrophilized. The method used for the research on the hydration of yeast protein is largely performed by immunoprecipitation followed by mass spectrometry and Western blot using a protein with a tandem affinity purification tag. It can be divided into the method of analysis by).

일단 면역침강법을 살펴보면, 생체 내에서 단백질은 다른 단백질과 결합을 통해 기능을 수행하기 때문에 특정 단백질을 정제하면 결합하는 다른 단백질들도 같이 정제가 된다. X와 결합하는 다른 단백질을 Y라 하면 X에 대한 항체를 넣어주었을 때 X/Y/X-항체의 복합침전물을 얻을 수 있는데 이 침전물을 전기영동 분석한 후 Y를 검출하면 X와 Y의 상호작용을 생화학적으로 분석할 수 있다. 이 방법은 많은 단백질 상호작용 연구에 널리 이용되고 있고, 단백질 수모화 연구에도 적용하여 수모화 되어 있는 미지의 단백질을 분리해낼 수 있다. 이와 더불어, 단백질을 구성하는 단백질 고유의 펩타이드들을 분석할 수 있는 질량분석 기법을 이용하여 면역침강법으로 복합 침전된 미지의 단백질들을 분석할 수 있다. 이를 이용하여 Johnson과 Blobel (Johnson and Blobel, J. Cell Biol. 1999, 147:981-994)은 단백질의 수모화가 세포 주기 진행에 큰 역할을 할 수 있음을 보고하였다. 세포 주기는 여러 단백질의 생성과 분해를 통해 순환하는데, 이때 진행과 멈춤이 정확하게 조절되어야만 세포가 정상적으로 살 수 있다. 특히 여러 단백질들 중에 셉틴 단백질들은 효모가 성장할 때 형성되는 버드넥(bud neck) 부분에 형성되는 단백질들을 말하 는데, 이들 단백질들이 수모화에 의해 정확하게 세포 주기를 조절하게 된다고 보고하였다. 즉, 수모화가 단백질의 기능을 조절하여 세포 성장에 중요한 역할을 하고 있다는 것을 보여준다. Hoege 등(Hoege et al., Nature 2002, 419:135-141)은 DNA 복제에 중요한 역할을 한다고 알려진 PCNA 단백질이 수모화된다는 것을 밝혔고, 이는 DNA 복구를 비롯한 DNA의 전반적인 안정성에 중요하다는 것을 보고하였다. Bachant 등(Bachant et al., Mol. Cell 2002, 9:1169-1182)은 세포 분열 시에 적도판에 배열되는 크로마틴의 구성 요소와 동원체의 코헤신 구조에 중요한 역할을 한다고 알려진 DNA topoisomerase II인 Top2 단백질이 수모화되는 것을 밝혔고, 수모화를 통해 Top2의 기능이 조절됨을 보고하였다. Once you look at immunoprecipitation, in vivo, proteins function by binding to other proteins, so when you purify a specific protein, other proteins that bind to it are also purified. If Y is the other protein that binds X, then a compound precipitate of X / Y / X-antibody can be obtained when the antibody against X is added. If Y is detected after electrophoresis analysis of this precipitate, X-Y interaction Can be analyzed biochemically. This method is widely used in many protein interaction studies, and can be applied to protein culturing studies to isolate unknown proteins that have been cultivated. In addition, it is possible to analyze the unknown protein complex precipitated by immunoprecipitation using a mass spectrometry technique that can analyze the protein-specific peptides constituting the protein. Using this, Johnson and Blobel (Johnson and Blobel, J. Cell Biol. 1999, 147: 981-994) reported that protein hydration may play a large role in cell cycle progression. The cell cycle circulates through the production and degradation of several proteins, in which the cells can live normally only if their progress and stoppage are precisely controlled. In particular, among the various proteins, the septin proteins, which are formed in the bud neck portion formed when the yeast grows, reported that these proteins precisely regulate the cell cycle by hydration. In other words, hydromyelination plays an important role in cell growth by regulating protein function. Hoege et al. (Hoege et al., Nature 2002, 419: 135-141) reported that the PCNA protein, known to play an important role in DNA replication, is condensed, which is important for the overall stability of DNA, including DNA repair. . Bachant et al. (Bachant et al., Mol. Cell 2002, 9: 1169-1182), a DNA topoisomerase II known to play an important role in the cohesine structure of chromatin components and isotopes, which are arranged on the equator plate during cell division. It was revealed that Top2 protein was hydrophobic and reported that the function of Top2 was regulated through hydrocyclization.

단백질의 수모화가 세포 내에서 많은 단백질의 기능을 조절하여 세포의 성장과 발달에 중요한 역할을 할 것이라 생각되지만, 실제로 많은 수의 수모 타겟 단백질이 발견되지 않았었다. 왜냐하면, 타겟 단백질의 양이 적어서 질량 분석이 어렵거나 수모화가 다양한 환경에서 특정 조건에서만 일어남으로써 정상상태에서는 타겟 단백질의 검출에 한계가 있을 수 있기 때문이다. 하지만 질량 분석 기술의 급진전으로 극소량(100 fmol 이하 수준)의 단백질만으로도 단백질 확인이 가능해졌다. 따라서 수모 단백질을 면역침강하여 정제된 미지의 단백질을 고성능 질량 분석 기법으로 분석하면 수모화되는 미량의 단백질도 분석할 수 있다. 이를 이용하여 새로운 수모화 단백질들을 찾아낼 수 있었고, 최근에는 특정 개체의 유전체 수준에서 수모화되는 단백질들을 찾으려는 연구들이 진행되고 있다. 그 예로, Zhou 등(Zhou et al., J. Biol. Chem. 2004, 279:32262-8)은 효모에서 수모 단백질의 N 말단에 FLAG 표지를 붙여 면역침강함으로써 수모화된 단백질들을 얻은 후, 질량 분석기를 이용하여 수모화 단백질을 분석할 수 있음을 보고하였다. 또한 Zhou 등은 세포는 다양한 세포 성장 환경에서 단백질의 수모화를 통해서 단백질의 기능을 조절하여 환경에 적응한다는 점에 착안하여, 과산화수소(H2O2) 혹은 에탄올(ethanol) 처리시의 단백질의 수모화 패턴 변화를 분석하여 80여 개의 수모화 단백질을 밝혀 내었다. Wohlschlegel 등(Wohlschlegel et al., J. Biol. Chem. 2004, 279:45662-8), Denison 등(Denison et al., Mol. Cell. Proteomics 2005, 4:246-254), Panse 등(Panse et al., J. Biol. Chem. 2004, 279:41346-41351)도 효모에서의 수모 단백질인 Smt3의 N 말단에 HIS 등의 표지를 붙인 후 면역침강시킨 후, 정제된 미지의 단백질을 질량 분석 기법으로 분석하여 각각 약 280, 220, 100 여 개의 수모화 단백질을 밝혀내었다. Although protein hydration is thought to play an important role in the growth and development of cells by regulating the function of many proteins in cells, a large number of targets for the development of hair are not actually found. This is because a small amount of the target protein may make it difficult to mass spectrometry or may occur in specific environments under various conditions, and thus, there may be a limit in detection of the target protein in a steady state. But rapid advances in mass spectrometry have made it possible to identify proteins with only very small amounts of proteins (up to 100 fmol). Therefore, if the unknown protein purified by immunoprecipitating the hydrophilic protein is analyzed by a high performance mass spectrometry technique, it is possible to analyze the trace protein that is hydrophilized. This has led to the discovery of new hydrocyclized proteins, and recently, studies are underway to find proteins that are hydrophilized at the genome level of a particular individual. For example, Zhou et al. (Jhou et al., J. Biol. Chem. 2004, 279: 32262-8), obtained yeasted proteins by immunoprecipitation by attaching a FLAG label to the N terminus of the yeast protein in yeast and then mass. It has been reported that an analyzer can be used to analyze hydrocyclized proteins. In addition, Zhou et al. Noted that cells adapt to the environment by regulating the function of the protein through hydration of the protein in a variety of cell growth environments, resulting in changes in the hydration pattern of the protein during hydrogen peroxide (H2O2) or ethanol treatment. The analysis revealed more than 80 hydrocyclized proteins. Wohlschlegel et al. (Wohlschlegel et al., J. Biol. Chem. 2004, 279: 45662-8), Denison et al. (Denison et al., Mol. Cell. Proteomics 2005, 4: 246-254), Panse et al. (Panse et. al., J. Biol. Chem. 2004, 279: 41346-41351) also subjected to immunoprecipitation after labeling the N-terminus of Smt3, a yeast protein in the yeast, with immunoprecipitation, and then mass purification of the purified unknown protein. As a result, about 280, 220, and about 100 hydrocyclized proteins were identified.

단백질 수모화 연구를 위해 연속 친화 정제 표지가 부착된 단백질을 이용하여 웨스턴 블롯으로 분석하는 방법도 있다. Ghaemmaghami 등(Ghaemmaghami et al., Nature 2003, 425: 737-741)은 연속 친화 정제 표지가 부착된 균주 라이브러리를 이용하여 효모 단백질의 전체적인 발현 프로파일을 포괄적으로 분석할 수 있음을 보고하였다. 이 연속 친화 정제 표지를 이용하면 특정 단백질의 발현 정도뿐만 아니라, 번역 후 단백질 수식(post-translational modification) 과정에 의한 단백질의 변화도 분석할 수 있다. 즉, 약 15 kDa 정도 크기의 유비퀴틴 혹은 수모 단백질이 타겟 단백질의 라이신 잔기에 공유결합을 이루게 되면 결합하는 단백질의 수에 따라 본래의 단백질 크기보다 더 큰 단백질이 검출될 것이다. 이를 이용하여 수모 에 의해 웨스턴 밴드의 이동 현상이 일어나는 수모화 단백질들을 구분해낼 수 있다. 그 예로, Wykoff 등(Wykoff et al., Mol. Cell. Proteomics 2005, 4:73-83)은 유전체 수준의 연속 친화 정제 표지 부착 라이브러리를 이용하여 약 80여 개의 수모화 단백질들을 밝혀내었다. 뿐만 아니라 상기의 면역침강법을 이용한 분석방법들에서도 면역침강법으로 밝혀낸 실험 결과를 확인하기 위하여, 웨스턴 블롯으로 단백질의 크기 변화를 분석하여 단백질의 수모화를 연구하였다. There is also a method of Western blot analysis using a protein with a continuous affinity purified label for protein hydrophilization studies. Ghaemmaghami et al. (Ghaemmaghami et al., Nature 2003, 425: 737-741) reported that a comprehensive library of yeast proteins can be comprehensively analyzed using a strain library with continuous affinity purification labels. Using this continuous affinity purification label, not only the expression level of a specific protein can be analyzed, but also the protein change caused by post-translational modification process. In other words, if a ubiquitin or a hair protein of about 15 kDa covalently binds to a lysine residue of a target protein, a protein larger than the original protein size will be detected depending on the number of binding proteins. This can be used to identify the hydrophilized proteins in which Western band shift occurs due to hydrocephalus. For example, Wykoff et al. (Wykoff et al., Mol. Cell. Proteomics 2005, 4: 73-83) identified about 80 hydrocyclizing proteins using a genome-level, continuous affinity purified labeling library. In addition, in order to confirm the experimental results found by the immunoprecipitation method in the analytical methods using the immunoprecipitation method, the hydrophilization of the protein was studied by analyzing the change in the size of the protein by Western blot.

하지만 상기의 수모화 단백질 분석 방법들은 모두 생체 외(in vitro) 조건에서 실험을 하기 때문에 실제 생체 내(in vivo) 상호작용과 상이한 경우가 많을 뿐만 아니라, 면역침강법과 웨스턴 방법 모두 단백질을 정제하는 과정에서 손실이 일어날 가능성이 많기 때문에 아주 강한 결합의 단백질 상호작용이 아니면 탐지하기 어렵다는 한계가 있다. 또한, 수모가 세포의 성장과 주위 환경 변화에 대한 인식과 반응에 중요함에도 불구하고, 상기의 분석 방법들은 생체 외 조건 실험방법이기 때문에, 주위 환경이나 세포 성장상태에 따른 단백질의 수모화 연구에 이용하기에는 한계가 있다. 따라서 생체 내 단백질 상호작용을 보다 정확하게 분석하기 위한 시스템의 개발이 필요하다.However, since all of the above hydrothermal protein analysis methods are tested in vitro, they are often different from the actual in vivo interactions, and both immunoprecipitation and Western methods purify proteins. Because of the high probability of loss in the system, there is a limitation that it is difficult to detect it unless it is a protein interaction with a very strong binding. In addition, although hair growth is important for recognition and response to cell growth and changes in the surrounding environment, the analytical methods described above are in vitro experiments, and thus are used to study protein hydration according to the environment and cell growth conditions. There is a limit to this. Thus, there is a need for the development of systems for more accurately analyzing protein interactions in vivo.

Hu 등(Hu et al., Mol. Cell 2002, 9:789-798)은 동물 세포에서 이분자 형광 상보 기법을 이용하여 단백질 상호작용 분석이 가능함을 보고하였다. 이분자 형광 상보 기법은 기존에 보고되었던 단백질 절편의 상보 작용(protein fragment complementation)을 형광 단백질에 적용시켜, 형광단백질을 N 말단 및 C 말단 절편으로 나눈 후 상호 작용을 알아보고자 하는 두 단백질 뒤에 각각 발현되게 한다. 만약 두 단백질이 상호작용을 하기 위해 가까워졌을 경우 형광단백질의 두 절편 또한 정상적인 3차 구조를 형성하여 형광을 나타내게 된다. Hu 등은 상기 시스템을 이용하여 황색 형광단백질을 N 말단과 C 말단으로 나눈 후 각각을 전사 인자인 Fos와 Jun 단백질 뒤에 부착시킨 후 동물 세포에서 발현되게 하여 두 전사 인자 사이에 단백질 상호작용이 이루어지고 있으며, 그 결합에 ZIP 도메인이 중요한 역할을 한다는 것을 보고하였다. 상기 시스템을 이용하여 Hu와 Kerppola (Hu & Kerppola, Nat. Biotechnol. 2003, 21:539-545)는 동물 세포에서 다양한 색의 형광 단백질을 이용한 복합적인 단백질 상호작용 분석을 하였고, Walter 등(Walter et al., Plant J. 2004, 40:428-438)과 Bracha 등(Bracha et al., Plant J. 2004, 40:419-427)은 비슷한 시기에 식물 세포에서 이분자 형광 상보 기법이 적용될 수 있음을 보고하였으며, Hoff 등(Hoff et al., Curr. Genet. 2005, 47:132-138)은 사상균(filamentous fungus)의 일종인 Acremonium chrysogenum에서도 이분자 형광 상보 기법이 적용될 수 있음을 보고하였다. 또한 최근에는 모델 생물인 효모에서도 이분자 형광 상보 기법을 이용한 단백질 상호작용 분석이 가능함을 보고(Sung & Huh, Yeast, 2007, 24:767-775)한 바 있어, 여러 개체에서 살아있는 세포 내에서 단백질 상호 작용분석과 상호 작용의 세포 내 위치를 분석할 수 있는 장점이 인정받고 있는 상황이다. 뿐만 아니라 최근의 몇몇 연구들을 통해 이분자 형광 상보 기법이 조건 특이적으로 변화하는 단백질 상호작용 분석에 적용 가능함이 보고되었기 때문에, 세포 성장 상태나 조건 특이적으로 변화하는 단백질의 수모화를 분석하기에 이분자 형광 상보 기법은 매우 적합한 방법이라고 할 수 있다. Hu et al. (Mol. Cell 2002, 9: 789-798) reported the possibility of protein interaction analysis using bi-molecule fluorescence complementation techniques in animal cells. The two-molecule fluorescence complementation technique applies a previously reported protein fragment complementation to a fluorescent protein, divides the fluorescent protein into N- and C-terminal fragments, and then expresses the two proteins after the two proteins for interaction. do. If the two proteins are close to each other for interaction, the two fragments of the fluorescent protein also form normal tertiary structures and fluoresce. Hu et al. Divided the yellow fluorescent protein into the N- and C-terminals using the above system, and then attached each of them to Fos and Jun proteins, which are transcription factors, and then expressed them in animal cells to make protein interactions between the two transcription factors. It has been reported that the ZIP domain plays an important role in the binding. Using this system, Hu and Kerppola (Hu & Kerppola, Nat. Biotechnol. 2003, 21: 539-545) analyzed complex protein interactions using fluorescent proteins of various colors in animal cells, and Walter et al. (Walter et al. al., Plant J. 2004, 40: 428-438) and Bracha et al. (Bracha et al., Plant J. 2004, 40: 419-427) suggest that bimolecular fluorescence complementarity techniques can be applied to plant cells at similar times. Hoff et al. (Curr. Genet. 2005, 47: 132-138) reported Acremonium , a type of filamentous fungus. It has also been reported that the bimolecular fluorescence complementation technique can be applied to chrysogenum . In recent years, yeast, a model organism, has been reported to analyze protein interactions using two-molecule fluorescence complementary techniques (Sung & Huh, Yeast, 2007, 24: 767-775). The advantages of analyzing the intracellular location of action analysis and interaction are recognized. In addition, several recent studies have reported that the two-molecule fluorescence complementation technique is applicable to analysis of protein interactions that change condition-specifically. The fluorescence complementary technique is a very suitable method.

하지만 이분자 형광 상보 기법이 갖는 많은 장점에도 불구하고 이 기법을 이용하여 번역 후 단백질 수식 과정을 분석한 연구는 아직 별로 없다. 한 예로, Fang과 Kerppola (Fang & Kerppola, PNAS 2004, 101:14782-87)가 이분자 형광 상보 기법을 이용하여 단백질의 유비퀴틴화와 수모화를 살펴본 연구가 보고되었다. 이 연구에서는 전사인자인 Jun 단백질에 형광단백질 C 말단을 부착시키고, 유비퀴틴과 수모 단백질의 N 말단에 형광단백질 N 말단을 부착시킨 후 동물 세포에서 발현되게 하여 Jun 단백질의 유비퀴틴화가 리소좀에서 일어나고 Jun 단백질의 안정성에 중요한 역할을 한다는 것을 밝혀냈다. 그러나 상기 연구는 목표 단백질의 상호작용을 실제 염색체상의 유전자가 아닌 플라스미드에 단백질을 코딩하는 유전자 서열과 형광 단백질의 절편을 코딩하는 서열을 넣어주어서 인위적으로 과량 발현되게 하는 것이기 때문에 실제 세포 내의 상황과는 다소 차이가 날 수 있으며 게다가 특정 환경 조건에서 동적으로 변화하는 상호작용의 분석에는 한계가 있다.Despite the many advantages of bimolecular fluorescence complementarity, however, few studies have been conducted to analyze the post-translational protein modification process. For example, Fang and Kerppola (Fang & Kerppola, PNAS 2004, 101: 14782-87) have been reported to investigate the ubiquitination and hydration of proteins using two-molecule fluorescence complementation. In this study, the fluorescent protein C terminus was attached to the transcription factor Jun protein, and the fluorescent protein N terminus was attached to the N terminus of the ubiquitin and scavenger protein, and then expressed in animal cells. It has been found to play an important role in stability. However, this study is different from the situation in the cell because the target protein interaction is artificially overexpressed by inserting the sequence encoding the protein and the sequence encoding the fragment of the fluorescent protein into the plasmid, not the gene on the actual chromosome. There may be some differences, and furthermore, there are limitations in the analysis of dynamically changing interactions under certain environmental conditions.

본 발명의 목적은 실제 세포 내에서 일어나는 특정 단백질의 수모화를 관찰함으로써 생체 내 조건에서의 단백질 수모화를 분석할 수 있는 방법 및 그에 사용되는 신규한 벡터들을 제공하는 것에 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a method for analyzing protein hydration under in vivo conditions by observing the hydration of a specific protein occurring in a cell and new vectors used therein.

상기한 목적을 달성하기 위하여, 본 발명은 염색체상 특정유전자에 형광단백질 일부를 포함하는 이배체 세포를 제작하여 세포내 특정단백질의 수모화(sumoylation)를 실시간으로 분석하는 방법을 제공한다. 본 발명의 이분자 형광 상보 기법을 이용하여 세포내 단백질의 수모화(sumoylation)를 실시간으로 분석하는 방법은 다음과 같은 단계를 포함한다. (가) 반수체 상태의 세포내 염색체의 특정 단백질 유전자 끝에 형광단백질 N 말단 일부를 형질전환시키고, 상기 반수체 상태의 세포와 교배하는 또 다른 반수체 상태의 세포내 염색체의 수모(Small ubiquitin-related modifier SUMO) 단백질 유전자 끝에 상기 N 말단 일부를 제외한 형광단백질 C 말단 일부를 형질전환시키는 단계; (나) 상기 형질전환된 두 세포를 각각 증식하는 단계; (다) 상기 증식된 세포들을 교배시켜 형성된 이배체만을 선택하는 단계; 및 (라) 상기 형성된 이배체를 형광현미경으로 관찰하는 단계.In order to achieve the above object, the present invention provides a method for producing a diploid cell comprising a portion of a fluorescent protein in a specific gene on a chromosome to analyze in real time the sumoylation of the specific protein in the cell. The method for analyzing the sumoylation of intracellular proteins in real time using the bimolecular fluorescence complementation technique of the present invention includes the following steps. (A) Small ubiquitin-related modifier SUMO, which transforms a portion of the fluorescent protein N terminus at a specific protein gene end of a haploid intracellular chromosome and crosses with the haploid cell. Transforming a portion of the fluorescent protein C terminus except for the N terminus part at the end of the protein gene; (B) propagating the two transformed cells, respectively; (C) selecting only diploids formed by crossing the proliferated cells; And (d) observing the formed diploid with a fluorescence microscope.

본 발명의 또 다른 양태는 상기 이배체 세포를 형성하는 반수체 세포를 제조하기 위한 벡터를 제공한다. 본 발명의 벡터는 특정 유전자에 형광단백질 절편을 부착할 때 유연성을 제공하는 연결 펩타이드 서열, 형광단백질 N말단 혹은 C말단 절편을 코딩하는 서열, 영양요구성 선별 유전자로서 특정 아미노산 합성에 관여하는 효소를 코딩하는 서열을 포함하는 벡터이다. 바람직하게는 도면 3에 기재된 유전자 지도를 갖는 형광단백질 N 말단 절편 부착용 플라스미드 벡터 또는 도면 4에 기재된 유전자 지도를 갖는 형광단백질 C 말단 절편 부착용 플라스미드 벡터이고, 보다 더 바람직하게는 서열번호 9의 pFA6a-HIS3MX6-pRPL7B-VN 벡터 또는 서열번호 10의 pFA6a-HIS3MX6-pRPL7B-VC 벡터이다. Another aspect of the invention provides a vector for preparing haploid cells forming said diploid cells. Vectors of the present invention are linked peptide sequences that provide flexibility in attaching fluorescent protein fragments to specific genes, sequences encoding fluorescent protein N- or C-terminal fragments, and enzymes that are involved in specific amino acid synthesis as nutritional selection genes. It is a vector containing the sequence to encode. Preferably, the plasmid vector for attaching the fluorescent protein N-terminal fragment having the gene map shown in FIG. 3 or the plasmid vector for attaching the fluorescent protein C-terminal fragment having the genetic map shown in FIG. 4, and more preferably, pFA6a-HIS3MX6 of SEQ ID NO: 9 -pRPL7B-VN vector or pFA6a-HIS3MX6-pRPL7B-VC vector of SEQ ID NO: 10.

상기 벡터들은 원하는 단백질의 N-말단에 VN 혹은 VC를 부착하기 위한 벡터이다. 형광단백질의 VN 혹은 VC를 원하는 단백질의 C-말단에 부착하느냐 아니면 N-말단에 부착하느냐는 실험의 목적이나 성격에 따라 결정되는데, C-말단에 부착하는 경우에는 단백질 자체의 프로모터(promoter)로 발현시킬 수 있는 장점이 있는 반면, N-말단에 부착하는 경우에는 사용하는 프로모터에 따라 단백질의 발현을 조절할 수 있다는 장점이 있다. 그런데 수모 단백질의 경우 C-말단 부분이 단백질의 기능에 중요한 역할을 하기 때문에 C-말단에 VN 혹은 VC를 부착하게 되면 정상적인 기능을 하지 못한다. 따라서 수모단백질은 반드시 N-말단에 형광단백질 일부를 부착하여야 한다. 본 발명의 pFA6a-HIS3MX6-pRPL7B-VC 벡터는 수모 단백질의 N-말단에 VC를 부착하는 동시에 발현양도 세포 내에 자연적으로 존재하는 수모 단백질의 양과 비슷하게 되게끔 RPL7B 프로모터를 사용하여 제작한 벡터이다.The vectors are vectors for attaching VN or VC to the N-terminus of the desired protein. Whether the VN or VC of the fluorescent protein is attached to the C-terminus or the N-terminus of the desired protein depends on the purpose or nature of the experiment.In the case of attaching to the C-terminus, the protein itself is a promoter. While there is an advantage that can be expressed, when attached to the N-terminal there is an advantage that can control the expression of the protein according to the promoter used. However, in the case of the hairpin protein, the C-terminal part plays an important role in the function of the protein, so when VN or VC is attached to the C-terminal part, it does not function normally. Therefore, hair hydrolyzate must attach a portion of fluorescent protein to N-terminus. The pFA6a-HIS3MX6-pRPL7B-VC vector of the present invention is a vector produced by using the RPL7B promoter to attach VC to the N-terminus of the hair protein and at the same time, the expression quantity is similar to the amount of hair protein present naturally in the cell.

본 발명은 이분자 형광 상보 기법을 이용하여 단백질의 수모화를 실시간으로 분석하기 위한 벡터와 그 분석방법을 제공한다. 본 발명의 수모화 분석방법은 자연 상태에서 일어나는 단백질의 수모화 및 세포내 위치를 실시간으로 분석할 수 있을 뿐만 아니라 형광현미경만으로도 용이하게 관찰할 수 있는 장점이 있기 때문에 세포내 단백질 상호작용 분석에 매우 유용하게 이용될 수 있다.The present invention provides a vector and an analysis method thereof for analyzing protein hydrophilicity in real time using a bimolecular fluorescence complementary technique. The method of hydromycinization of the present invention is very useful for analyzing intracellular protein interactions because it has the advantage that it can be easily observed only by fluorescence microscopy as well as the real-time analysis of the hydrophobicity and intracellular location of proteins occurring in the natural state. It can be usefully used.

Next, the yeast colony PCR method confirms that the fluorescent protein fragments are properly attached to the target gene by using the 500 bp upper sequence and the starting sequence of the fluorescent protein attachment vector as primers at the end of the target gene. Yeast colony PCR method is as follows. Once 20 μl of H 2 O was scraped with a tip of cells grown in histidine-deficient glucose medium, the solution was well removed, and then boiled at 100 ° C. for 15 minutes using a PCR machine.

실시예Example 2 : 형광 단백질 N 말단 및 C 말단을 형질전환시킨 효모의 교배 2: Crossing of Yeast Transformed with Fluorescent Protein N- and C-Terminals

상기 형질전환 균주들을 효모 콜로니 PCR 방법으로 확인한 후, 이분자 형광 상보 기법 분석을 위해 형광단백질의 N 말단과 C 말단이 모두 형질전환된 균주를 제작하였다. 상기 숙주 세포로 사용한 BY47418은 교배형(mating type)이 a이고 HIS3, LEU2 , MET15URA3 유전자가 없는 변이체이며, 형광단백질 N 말단이 His3 마커(marker)와 함께 형질전환된 상태이고, BY4742는 교배형이 α이고 HIS3 , LEU2 , LYS2 URA3 유전자가 없는 변이체이며, 형광단백질 C 말단이 His3 마커와 함께 형질전환 된 상태이다. 상기 형광단백질의 N 말단과 C 말단이 부착된 두 숙주세포의 교배형이 다르기 때문에 교배가 가능하며, 특히 상기의 경우 메치오닌, 라이신 결핍 포도당 배지(SC-M-K)에서 형광단백질 N 말단과 C 말단이 모두 발현되는 이배체의 효모 균주를 제작할 수 있다. 교배 과정은 다음과 같다. 상기 방법으로 형광단백질의 절편이 형질전환된 BY4741, BY4742 균주를 YPD 액체 배지 5 ml에서 30℃ 배양기를 이용하여 15시간동안 OD600=1.0이 되도록 하였다. 그 후 1.5 ml 튜브에 각 균주를 500 ㎕씩 넣은 후 상온에서 2시간 이상 배양시키면 교배가 이루어지고, 교배된 이배수체 균주를 선별해내기 위해 메치오닌과 라이신 결핍 포도당배지 플레이 트에 분주하여 3일 정도 배양하면 콜로니들이 형성되는 것을 확인하였다. After confirming the transformed strains by the yeast colony PCR method, a strain in which both the N- and C-terminal of the fluorescent protein were transformed was prepared for analysis of two-molecule fluorescence complementation technique.

수모 단백질이 수모로서의 기능을 하기 위해서는 수모 유전자에서 수모 전구체 단백질이 합성된 후 수모 특이적 프로티에이즈(Ulp1)에 의해 수모 단백질의 C 말단의 특정부위(-GGATY)가 잘려 -GG부분이 노출이 되어야만 한다. 따라서 이분자 형광 상보 기법을 위한 C 말단 부착은 세포 내에서 제대로 작용을 못하기 때문에, 수모화 단백질 연구를 위해서는 단백질의 N말단에 형광단백질의 단편을 부착해야만 한다. 이를 위해 본 연구에서는 이전 연구(실시예 1의 (2) 참조)를 통해 제작된 형광단백질 C 말단 절편 부착용 벡터를 DNA 주형으로 실시예 1번의 방법으로 SMT3-F4(서열번호 1)와 SMT3-R5-VC(서열번호 2)를 프라이머로 사용하여 BY4742 세포의 SMT3 유전자의 N 말단 부분에 형광단백질 C 말단을 부착시킨 균주를 만들었다. In order to function as a hair growth, the hair growth protein is synthesized from the hair growth gene, and then the specific terminal (-GGATY) of the C terminus of the hair growth protein is cut by the hair growth specific protease (Ulp1). Should be. Therefore, the C-terminal attachment for the two-molecule fluorescence complementation technique does not work properly in the cell, so for the study of the hydrophobic protein, it is necessary to attach a fragment of the fluorescent protein to the N terminus of the protein.

상기 결과들은 본 발명의 이분자 형광 상보 기법을 이용한 단백질의 수모화 분석이 실제로 적용가능함을 보여준다. 기존에 수모화 된다고 보고된 Rps3, Hmo1, Cet1 단백질들에 형광단백질 N 말단을 붙인 균주와 Smt3에 형광단백질 C 말단이 부착된 균주를 교배한 이배수체 효모 균주를 제작하여 형광 현미경을 관찰해보았을 때, 형광이 발하는 것을 확인할 수 있었고 또한 수모화가 일어나는 세포 내 위치도 볼 수 있었다. 음성 대조군의 경우 형광을 거의 발하지 않는 것으로 보아 이분자 형광 상보 기법을 이용한 단백질 수모화 분석이 우연히 형광단백질 단편이 세포 내에서 결합하여 생기는 현상이 아닌 실제 단백질의 수모화임을 정확히 볼 수 있다. The results show that the hydrothermal analysis of proteins using the bimolecular fluorescence complementation technique of the present invention is practically applicable. Observation of fluorescence microscopy was carried out to prepare a diploid yeast strain in which a strain having a fluorescent protein N terminus attached to Rps3, Hmo1, and Cet1 proteins previously reported to be hydrophilized and a strain having a fluorescent protein C terminus attached to Smt3 were produced. It was confirmed that the fluorescence emitted, and also the location within the cell where the hydration occurs. In case of the negative control, the fluorescence rarely emits, indicating that the protein hydration analysis using the bimolecular fluorescence complementary technique is the actual protein hydration, not a phenomenon caused by the incorporation of the fluorescent protein fragment in the cell.
