CAPN3 Antibody / Calpain 3

Calpain 3 is a member of the calpain family of proteases, which are enzymes that break down proteins in the body. Unlike other calpain enzymes that are present in various tissues, Calpain 3 is predominantly found in skeletal muscle. Its main function is to regulate the turnover of muscle proteins, ensuring that they are properly maintained and repaired. One of the key roles of Calpain 3 is to maintain the structural integrity of muscle fibers. It is involved in the breakdown of damaged or misfolded proteins, preventing them from accumulating and causing muscle dysfunction. Additionally, Calpain 3 plays a vital role in muscle regeneration, helping to repair damaged fibers and promote muscle growth. Deficiencies in Calpain 3 have been linked to various muscle disorders, including limb-girdle muscular dystrophy type 2A. In individuals with this condition, mutations in the CAPN3 gene lead to impaired muscle function and weakness.
