Definitions
- the present invention relates to a MG53 mutant (also referred to as a MG53 protein mutant), and the use of the MG53 mutant for protecting heart palpitations and treating heart diseases caused by cell death, in particular while protecting the heart while protecting the heart It avoids side effects such as insulin resistance, obesity, diabetes and metabolic syndrome that are accompanied by MG53, which is also cardioprotective. Background technique
- MG53 is a skeletal muscle-specific protein mitsugumin53, referred to as MG53; or TRIM72.
- Mitsugumin53 MG53
- TAM muscle-specific tripartite motif family
- RING, B-BOX, and coiled domains these proteins are labeled with ubiquitin for degradation on egg A, which is no longer needed by cells.
- MG53 is also an important component of the cell membrane repair mechanism.
- MG53 protects the heart, which means it protects against heart damage by increasing the amount of MG53.
- MG53 has a negative effect that cannot be ignored and is considered a major hazard.
- the increase in MG53 content can cause insulin resistance, obesity, diabetes and metabolic syndrome while protecting the heart.
- MG53 protects the heart with side effects such as insulin resistance, obesity and diabetes. This is a concern of the industry and does not want it: ⁇ A problem of coexistence of negative effects, so far no solution has been resolved. Summary of the invention
- the present invention provides a mutant of MG53 which mutates to any one or two or more cysteines of seven cysteines in the N-terminal RING domain of the MG53 protein to a non-polar amino acid (for example) Alanine) MG53 protein 3 ⁇ 4 variant.
- the MG53 protein mutant protects the heart while avoiding side effects such as insulin resistance, obesity, diabetes, and metabolic syndrome that are accompanied by the same cardioprotective effect of MG53.
- G53 protects the heart, which means it can protect against heart damage by increasing the amount of MG53.
- the increase in MG53 content can cause insulin resistance, obesity, diabetes and generation while protecting the heart.
- MG53 protects the heart with side effects such as insulin resistance, obesity, diabetes and metabolic syndrome.
- this application has carried out a lot of research work, the main purpose is to mutate the MG53 protein, hope not to cause insulin resistance, obesity, diabetes and metabolic syndrome. Under the premise of side effects, the mutant is retained to exercise the cardioprotective function, but without the corresponding side effects.
- the present invention provides a MG53 mutant which is one of the seven cysteines of the N-terminal RING domain of MG53 or two or more cysteines mutated to a non-polar amino acid. Mutant; the seven cysteines are at position 14, 17th, 29th, 34th, 37th, 53rd, 56th of the RING domain, respectively. Site.
- cysteines are important sites in the RING finger region of MG53, while the RING finger region is responsible for its E3 ligase activity, degradation of its substrate, and induction of insulin resistance, obesity, diabetes, and metabolic syndrome. The side effects are necessary, so the inventors chose these seven cysteines as research objects.
- the above-mentioned MG53 protein mutant provided by the present invention can protect the heart while avoiding side effects such as insulin resistance, obesity, diabetes and metabolic syndrome accompanying MG53, and the cardioprotective effect is not affected at all.
- the non-polar amino acid is alanine, glycine, valine, leucine, isoleucine, valine, phenylalanine, tryptophan, or methionine.
- the non-polar amino acids are alanine, glycine, -; valine, valine, valine and isoleucine.
- the non-polar amino acid is alanine.
- the MG53 mutant is selected from any one of MG53CMA, MG53C17A, MG53C29A, MG53C34A. MG53C37A, MG53C53A, and MG53C56A.
- the MG53 mutant of the present invention includes primates, rats and mice.
- the original wild sequence was selected as the NCBI number of mouse MG53 (TRIM72) mRNA: NM 001079932.3. Other sequences may be selected,
- the MG53 mutant provided by the present invention is a MG53 protein mutant, and the 14th position of the N-terminal RING ⁇ finger region of the mutation is alanine, that is, the N-terminal RING finger region of the MG53 protein.
- cystine is replaced by alanine, it is mutated to become the MG53 mutant of the present invention, and the cysteine is at the 14th position in the MG53 protein, and the alanine is also substituted at the 14 position, that is, the present invention.
- the MG53 mutant was MG53C14A.
- the present invention uses alanine as an example to illustrate the MG53 mutant, and it should be noted that: the cyst of the present invention
- the 3 ⁇ 4 acid mutation may be selected from not only A (alanine), but also any of the 8 non-polar amino acids, such as glycine, leucine, valine, proline or isoleucine. It also has the effect of exercising heart protection function under the premise of MG53 mutation without causing side effects such as insulin resistance, obesity, diabetes and metabolic syndrome.
- the mutation method of other non-polar amino acids is the same as that of ruthenium and valine, and will not be described herein.
- MG53 can act as a structural protein to promote the repair of cell membrane damage in skeletal muscle and myocardium, and also regulate intracellular vesicle transport and skeletal muscle cell regeneration; in addition, in MG53, MG53 is also mediated.
- the combination of Caveolin-3 and PI3K activates the reperfusion injury salvage kinase pathway (RISK pathway), which plays an important protective role in cardiac ischemic preconditioning.
- RISK pathway reperfusion injury salvage kinase pathway
- the inventors found that the MG53 protein is a RING domain (also called a RING finger region), a B-box domain, a Coiled-coil domain, and a SPRY structure which are recognized to have ⁇ 3 ligase activity. Domain composition. From the results of amino acid sequence analysis of MG53, only the RING domain is a recognized domain containing FJ ubiquitin ligase activity, and therefore, the inventors determined that the E3 ubiquitin ligase activity of MG53 is in RING.
- the first zinc-bonded cysteine in the zinc finger structure of the RING domain the tenth cysteine in the amino acid sequence of wild-type mouse MG53, which maintains the RING domain E3 ubiquitin ligase
- the key is.
