MG53 Mutants, Methods of Making the Same, and Uses Thereof

Abstract

The present invention relates to an MG53 mutant, wherein the MG53 mutant is identical to the amino acid sequence of a wild-type MG53 except for at least one serine in the coiled-coil-SPRY region of the wild-type MG53, which is deleted and/or mutated into any other non-serine or non-threonine amino acid(s). The present invention also relates to a pharmaceutical composition comprising the MG53 mutant, a nucleic acid encoding the MG53 mutant, a method for preparing the MG53 mutant, use of the MG53 mutant in the manufacture of a medicament for treating heart diseases, diabetic cerebrovascular diseases, diabetic ocular complications, diabetic neuropathy, diabetic foot, kidney diseases, and diseases associated with cellular and/or tissue damage. In particular, the MG53 mutant of the present invention may avoid or reduce metabolic side effects, such as, insulin resistance, obesity, diabetes, hypertension, dyslipidemia, etc., brought by the wild-type MG53, while treating heart diseases, diabetic cerebrovascular diseases, diabetic ocular complications, diabetic neuropathy, diabetic foot, kidney diseases, and diseases associated with cellular and/or tissue damage.
