Abstract

The present invention relates to a method for diagnosing Parkinson's disease using the PARK2 mutant gene. Specifically, the PARK2 mutation inhibits the degradation of AIMP2 and SNCA proteins, thereby causing and aggravating Parkinson's disease. Therefore, the therapeutic effect can be increased by using the composition of the present invention to check whether there is a PARK2 mutation or not and the possibility of Parkinson's disease in advance. In addition, a therapeutic agent for Parkinson's disease can be developed by screening a substance capable of changing the activity of the PARK2 mutant.

J. Hum. Genet., 60, 1997, 588 ,; Kitada, Nature 392, 1998, 605; Abbas, Hum.Mol. Genet. 8, 1999, 567; Tassin, Am, J, Hum. Genet. , 63, 1998, 88 and Lucking, N. Engl. J. Med. 342, 2000, 1560-7). Other loci, such as PARK6 and PARK7, have also been found to be combustible and have a high incidence in families with autosomal recessive genetic Parkinsonian history (Valente, Am. J. Hum. Genet. 68, 2001, 895; van Dujin, Am. J. Hum. Genet. 69, 2001, 629). Mutations in the alpha-synuclein gene (PARK1) have also been found in families with combustible, autosomal recessive genetic Parkinsonian history (Polymeropoulos, Science 276, 1997, 2045). In addition to genetic predisposition, environmental factors such as overexposure to pesticides (Vanacore, Neurol Sci., Sep; 23 Suppl 2, 2002, page 119) may also be representative risk factors. In addition, various stimuli such as excessive reactive oxygen species production, oxidative stress, misfolded proteins and impaired mitochondrial function are known to cause Parkinson's disease.

본 명세서에서 사용한 용어 "파킨슨병(Morbus Parkinson 및 Parkinson's disease)"은 본 특허 출원에서 동의어로 사용되고, 특발성 및 유전적 파킨슨병을 포함한다. 본 명세서에서 사용한 용어 "PARK2"는 파킨슨병 단백질 2(Parkinson Disesase Protein 2)를 의미하며, 상기 PARK2는 세포내에서 E3 유비퀴틴 리가제 효소(E3 ubiquitin ligase enzyme)의 기능을 수행한다. 상기 효소는 기질 단백질을 분해시켜 세포의 항상성을 유지한다. PARK2의 기질로서 AIMP2(aminoacyl-tRNA complex interacting multifuncional protein-2)와 SNCA(α-synuclein)가 PARK2에 의해 분해된다. 상기 AIMP2 및 SNCA 단백질은 신경세포죽음 유도 기능을 수행하는 것으로 보고된 바 있다.The term "Morbus Parkinson and Parkinson's disease" as used herein is used synonymously in this patent application and includes idiopathic and genetic Parkinson's disease. As used herein, the term "PARK2" refers to Parkinson's Disease Protein 2, wherein PARK2 performs the function of an E3 ubiquitin ligase enzyme in cells. The enzyme breaks down matrix proteins to maintain cell homeostasis. As a substrate of PARK2, aminoacyl-tRNA complex interacting multifuncional protein-2 (AIMP2) and SNCA (α-synuclein) are degraded by PARK2. The AIMP2 and SNCA proteins have been reported to perform neuronal cell death induction function.
상기 PARK2에서 돌연변이는 효소 기능을 상실한 돌연변이를 의미한다. 특히, 상기 돌연변이는 기질단백질인 AIMP2 및/또는 SNCA의 분해가 억제된 것을 의미한다. 또한, 상기 PARK2에서 돌연변이는 서열번호 1의 PARK2에서 458번의 아미노산이 천연형과 다른 아미노산을 갖는 것일 수 있다. 천연형의 PARK2는 458번의 아미노산이 메티오닌(Met, M)이나, 돌연변이 PARK2는 메티오닌 이외의 다른 아미노산 일 수 있다. 바람직하게, PARK2에서 돌연변이 서열번호 1의 458번째 아미노산이 메티오닌에서 루이신(Leu, L)일 수 있다. 바람직하게는 PARK2 돌연변이는 서열번호 3의 아미노산 서열을 가질 수 있다.Mutation in PARK2 refers to a mutation that has lost enzyme function. In particular, the mutation means that degradation of the substrate proteins AIMP2 and / or SNCA is inhibited. In addition, the mutation in the PARK2 may be that amino acids 458 in PARK2 of SEQ ID NO: 1 having an amino acid different from the natural type. The native PARK2 has 458 amino acid methionine (Met, M), but the mutant PARK2 may be other amino acid than methionine. Preferably, the 458th amino acid of mutation SEQ ID 1 in PARK2 may be leucine (Leu, L) in methionine. Preferably, the PARK2 mutation may have an amino acid sequence of SEQ ID NO.
천연형 PARK2는 E3 유비퀴딘을 통해 AIMP2 및/또는 SNCA의 분해를 촉진시켜, 세포내에 상기 단백질이 축적되지 않으며, 상기 단백질에 의한 파킨슨병이 유발되지 않는다. 그러나, 돌연변이 PARK2는 AIMP2 및/또는 SNCA의 분해가 억제되어, 세포내에 상기 단백질이 축적되게 된다. 그로인해, 상기 단백질에 의한 파킨슨병이 유발되게 된다.Native PARK2 promotes the degradation of AIMP2 and / or SNCA via E3 ubiquidine such that the protein does not accumulate in cells and Parkinson's disease caused by the protein is not induced. However, mutant PARK2 inhibits the degradation of AIMP2 and / or SNCA, causing the protein to accumulate in the cell. This leads to Parkinson's disease caused by the protein.
상기 조성물의 일 구체예로는 PARK2의 돌연변이를 검출할 수 있는 프로브, 앱타머 또는 프라이머를 포함할 수 있다.One embodiment of the composition may include a probe, aptamer or primer that can detect a mutation of PARK2.

Probes that can recognize and bind to mutation sites can be used to recognize nucleic acids encoding PARK2 mutant proteins.
용어 “프라이머”는 짧은 자유 3말단 수산화기(free 3' hydroxyl group)를 갖는 핵산 서열로 상보적인 템플레이트(template)와 염기쌍(base pair)을 형성할 수 있고 템플레이트 가닥 복사를 위한 시작 지점으로 기능을 하는 짧은 핵산 서열을 의미한다. 프라이머는 적합한 온도 및 적합한 완충액 내에서 적합한 조건(즉, 4종의 다른뉴클레오시드 트리포스페이트 및 중합반응 효소) 하에서 주형-지시 DNA 합성의 개시점으로 작용할 수 있는 단일-가닥 올리고뉴클레오타이드를 의미한다. 프라이머의 적합한 길이는 다양한 요소, 예컨대, 온도와 프라이머의 용도에 따라 변화가 있을 수 있다. 또한, 프라이머의 서열은 주형의 일부 서열과 완전하게 상보적인 서열을 가질 필요는 없으며, 주형과 혼성화되어 프라이머 고유의 작용을 할 수 있는 범위 내에서의 충분한 상보성을 가지면 충분하다. 따라서 본 발명에서의 프라이머는 주형인 PARK2 돌연변이 유전자의 뉴클레오타이드 서열에 완벽하게 상보적인 서열을 가질 필요는 없으며, 이 유전자 서열에 혼성화되어 프라이머 작용을 할 수 있는 범위 내에서 충분한 상보성을 가지면 충분하다. 이때, 상기 프라이머는 돌연변이된 유전자 부분을 포함할 수 있게 고안될 수 있으며, 또는 프라이머에 의해 증폭된 산물내에 돌연변이된 유전자 부분을 포함할 수 있도록 고안될 수 있다.The term “primer” is a nucleic acid sequence with a short free 3 ′ hydroxyl group, which can form complementary templates and base pairs and serves as a starting point for template strand copying. Short nucleic acid sequence. By primer is meant a single-stranded oligonucleotide capable of acting as an initiation point for template-directed DNA synthesis under suitable conditions and in suitable buffers (ie, four different nucleoside triphosphates and polymerases). Suitable lengths of primers can vary depending on various factors, such as temperature and the use of the primer. In addition, the sequence of the primer need not have a sequence that is completely complementary to some sequences of the template, it is sufficient to have sufficient complementarity within the range that can hybridize with the template to perform the primer-specific action. Therefore, the primer in the present invention does not need to have a sequence that is perfectly complementary to the nucleotide sequence of the PARK2 mutant gene as a template, and it is sufficient to have sufficient complementarity within a range capable of hybridizing to the gene sequence to act as a primer. In this case, the primer may be designed to include the mutated gene portion, or may be designed to include the mutated gene portion in the product amplified by the primer.

Specifically, the method comprises the steps of: 1) separating genomic DNA from a sample derived from an individual; 2) detecting a mutation site of the PARK2 gene in the genomic DNA isolated in step 1); And 3) identifying the mutation site detected in step 2).
이때, 상기 단계 1)의 시료는 혈액인 것이 바람직하나, 이에 한정되지 않는다.In this case, the sample of step 1) is preferably blood, but is not limited thereto.
이때, 상기 2) 단계는 서열번호 5 및 6의 프라이머를 이용하여 수행할 수 있다. 또한, 상기 돌연변이는 서열번호 1의 458의 메티오닌이 다른 아미노산으로 치환된 것일 수 있으며, 바람직하게는, 서열번호 1의 458번째 메티오닌이 루이신으로 치환된 것이 바람직하나, 이에 한정되지 않는다.In this case, step 2) may be performed using the primers of SEQ ID NOs: 5 and 6. In addition, the mutation may be substituted with another amino acid of 458 methionine of SEQ ID NO: 1, Preferably, the 458th methionine of SEQ ID NO: 1 is preferably substituted with leucine, but is not limited thereto.
상기 단계 2)에서 검출은 시퀀싱 분석, 마이크로어레이(microarray)에 의한 혼성화, 대립유전자 특이적인 PCR(allele specific PCR), 다이나믹 대립유전자 혼성화 기법(dynamic allele-specific hybridization; DASH), PCR 연장 분석 또는 TaqMan 프로브 PCR 분석에 의하여 수행되는 것이 바람직하나, 이에 한정되지 않는다.The detection in step 2) can include sequencing analysis, hybridization by microarray, allele specific PCR, dynamic allele-specific hybridization (DASH), PCR prolongation analysis or TaqMan It is preferably performed by probe PCR analysis, but is not limited thereto.
상기 방법 중, 시퀀싱 분석은 염기서열 결정을 위한 통상적인 방법을 사용할 수 있으며, 자동화된 유전자분석기를 이용하여 수행될 수 있다(Sanger, F. et al., Proc. Natl. Acad. Sci. USA., 74(12), 5463-5467, 1977; Maxam, A. M. and Gilbert, W., Proc. Natl. Acad. Sci. USA., 74(2), 560-564, 1997).Of these methods, sequencing analysis can use conventional methods for sequencing and can be performed using an automated genetic analyzer (Sanger, F. et al., Proc. Natl. Acad. Sci. USA. , 74 (12), 5463-5467, 1977; Maxam, AM and Gilbert, W., Proc. Natl. Acad. Sci. USA., 74 (2), 560-564, 1997).
대립유전자 특이적인 PCR 분석은 돌연변이가 위치하는 염기를 3' 말단으로 하여 고안한 프라이머를 포함한 프라이머 세트로 상기 돌연변이가 위치하는 DNA 단편을 증폭하는 PCR 방법을 의미한다. 상기 방법의 원리는, 예를들어, 특정 염기가 A에서 C로 치환된 경우, 상기 A를 3' 말단염기로 포함하는 프라이머 및 적당한 크기의 DNA 단편을 증폭할 수 있는 반대방향 프라이머를 고안하여 PCR 반응을 수행할 경우, 상기 돌연변이 위치의 염기가 "A"인 경우에는 증폭반응이 정상적으로 수행되어 원하는 위치의 밴드가 관찰되고, 염기가 "C"로 치환된 경우 상기 프라이머는 주형 DNA에 상보결합할 수 있으나, 3' 말단 쪽이 상보결합을 하지 못함으로써 증폭반응이 제대로 수행되지 않는 특징을 이용한 것이다(Newton, C. R. et al., Nucleic Acids Res., 17(1), 2503-2516, 1989).Allele-specific PCR analysis refers to a PCR method of amplifying a DNA fragment in which the mutation is located with a primer set including a primer designed with the base where the mutation is located at the 3 'end. The principle of the method is, for example, when a specific base is substituted from A to C, PCR by designing a primer containing A as the 3 'terminal base and a reverse primer capable of amplifying a DNA fragment of a suitable size. When the reaction is carried out, when the base of the mutation position is "A", the amplification reaction is normally performed, and a band of the desired position is observed. When the base is substituted with "C", the primer is complementary to the template DNA. However, the amplification reaction may not be performed properly because the 3 'end is not complementary (Newton, CR et al., Nucleic Acids Res., 17 (1), 2503-2516, 1989).
TaqMan 프로브 PCR 분석은(Livak, K. J., Genet. Anal., 14, 143-149, 1999)은 1) 원하는 DNA 단편을 증폭할 수 있도록 프라이머 및 TaqMan 프로브를 설계 및 제작하는 단계; 2) 서로 다른 대립유전자의 프로브를 FAM 염료 및 VIC 염료로 표지(Applied Biosystems, USA)하는 단계; 3) 상기 DNA를 주형으로 하여 상기의 프라이머 및 프로브를 이용하여 PCR을 수행하는 단계; 4) 상기의 PCR 반응이 완성된 후, TaqMan 분석 플레이트를 염기서열 분석기로 분석 및 확인하는 단계; 및 5) 상기 분석결과로부터 단계 1의 폴리뉴클레오티들의 유전자형을 결정하는 단계를 포함할 수 있다.TaqMan probe PCR analysis (Livak, K. J., Genet. Anal., 14, 143-149, 1999) includes: 1) designing and constructing primers and TaqMan probes to amplify the desired DNA fragments; 2) labeling probes of different alleles with FAM dye and VIC dye (Applied Biosystems, USA); 3) performing PCR using the primers and probes using the DNA as a template; 4) after the PCR reaction is completed, analyzing and confirming the TaqMan assay plate with a sequencing analyzer; And 5) determining the genotype of the polynucleotides of step 1 from the analysis result.
다이나믹 대립유전자 혼성화(DASH) 분석은 프린스 등에 의해 고안된 방법으로 수행할 수 있다(Prince, J. A. et al., Genome Res. 11(1), 152-162, 2001). Dynamic allele hybridization (DASH) analysis can be performed by a method devised by Prince et al. (Prince, J. A. et al., Genome Res. 11 (1), 152-162, 2001).
PCR 연장 분석은 먼저 돌연변이가 위치하는 염기를 포함하는 DNA 단편을 프라이머 쌍으로 증폭한 다음, 반응에 첨가된 모든 뉴클레오티드를 탈인산화시킴으로써 불활성화시키고, 여기에 돌연변이에 특이적인 연장 프라이머, dNTP 혼합물, 디디옥시뉴클레오티드, 반응 완충액 및 DNA 중합효소를 첨가하여 프라이머 연장반응을 수행함으로써 이루어진다. 이때, 연장 프라이머는 돌연변이가 위치하는 염기의 5' 방향의 바로 인접한 염기를 3' 말단으로 삼으며, dNTP 혼합물에는 디디옥시뉴클레오티드와 동일한 염기를 갖는 핵산이 제외되고, 상기 디디옥시뉴클레오티드는 돌연변이를 나타내는 염기 종류 중 하나에서 선택된다. 예를 들어, A에서 C로의 치환이 있는 경우, dGTP, dCTP 및 TTP 혼합물과 ddATP를 반응에 첨가할 경우, 상기 치환이 일어난 염기에서 프라이머는 DNA 중합효소에 의하여 연장되고, 몇 개의 염기를 지난 후 A 염기가 최초로 나타나는 위치에서 ddATP에 의하여 프라이머 연장반응이 종결된다. 만일 상기 치환이 일어나지 않았다면, 그 위치에서 연장반응이 종결되므로, 상기 연장된 프라이머의 길이를 비교함으로써 돌연변이를 나타내는 염기 종류를 판별할 수 있게 된다.PCR extension analysis first inactivates a DNA fragment containing a base where the mutation is located by amplifying a pair of primers and then inactivating by dephosphorylation of all nucleotides added to the reaction, followed by extension primers specific for the mutation, dNTP mixtures, Didi By adding a oxynucleotide, reaction buffer and DNA polymerase to effect primer extension. At this time, the extension primer is a 3 'end of the base immediately adjacent to the 5' direction of the base where the mutation is located, the dNTP mixture excludes a nucleic acid having the same base as the didioxynucleotide, the didioxynucleotide represents a mutation It is selected from one of the base types. For example, if there is a substitution from A to C, when a mixture of dGTP, dCTP and TTP and ddATP are added to the reaction, the primer at the base where the substitution has occurred is extended by DNA polymerase and after several bases The primer extension is terminated by ddATP at the position where A base first appears. If the substitution has not occurred, since the extension reaction is terminated at the position, it is possible to determine the base type indicating the mutation by comparing the length of the extended primer.
이때, 검출방법으로는 연장 프라이머 또는 디디옥시뉴클레오티드를 형광 표지한 경우에는 일반적인 염기서열 결정에 사용되는 유전자 분석기(예를 들어, ABI사의 Model 3700 등)를 사용하여 형광을 검출함으로써 상기 돌연변이를 검출할 수 있으며(Chen, J., Genome Res., 10(4), 549-557, 2000), 표지되지 않은 연장 프라이머 및 디디옥시뉴클레오티드를 사용할 경우에는 MALDI-TOF(matrix assisted laser desorption ionization-time of flight) 기법을 이용하여 분자량을 측정함으로써 상기 돌연변이를 검출할 수 있다(Ross, P. L., Anal. Chem, 69(20), 4197-4202, 1997).In this case, as a detection method, when fluorescently labeling an extension primer or didioxynucleotide, the mutation may be detected by detecting fluorescence using a gene analyzer (for example, ABI's Model 3700, etc.) used for general sequencing. (Chen, J., Genome Res., 10 (4), 549-557, 2000), and matrix assisted laser desorption ionization-time of flight when using unlabeled extension primers and didioxynucleotides. The mutations can be detected by measuring molecular weight using the technique (Ross, PL, Anal. Chem, 69 (20), 4197-4202, 1997).

이때, 상기 PAKR2 돌연변이는 서열번호 3의 아미노산 서열을 갖는 것일 수 있다. 또한, PARK2 돌연변이 활성의 증가는 1) SNCA 또는 AIMP2 단백질의 분해가 억제되거나 및/또는 2) PARK2 돌연변이의 오토유비퀴틴화가 감소되는 것을 통해 확인할 수 있다. 또한, 상기 시료는 천연물 추출물, 화합물, 핵산, 단백질 또는 항체에서 선택되는 어느 하나일 수 있다.In this case, the PAKR2 mutation may be one having an amino acid sequence of SEQ ID NO: 3. In addition, increased PARK2 mutant activity can be confirmed by 1) inhibiting degradation of SNCA or AIMP2 proteins and / or 2) reducing autoubiquitination of PARK2 mutants. In addition, the sample may be any one selected from natural product extracts, compounds, nucleic acids, proteins or antibodies.
