Myotilin: Lysates

Striated muscle sarcomeres are highly organized structures composed of actin (thin) and myosin (thick) filaments that slide past each other during contraction. The integrity of sarcomeres is controlled by a set of structural proteins, among which are titin (TTN; MIM 188840), a giant molecule that contains several immunoglobulin (Ig)-like domains and associates with thin and thick filaments, and alpha-actinin (ACTN1; MIM 102575), an actin cross-linking protein. Mutations in several sarcomeric and sarcolemmal proteins have been shown to result in muscular dystrophy and cardiomyopathy.[supplied by OMIM]
