Dystrobrevin Alpha (DTNa)

A dystrophin-containing glycoprotein complex (DGC) links the basal lamina surrounding each muscle fibre to the fibre"""s cytoskeleton, providing both structural support and a scaffold for signalling molecules. Mutations in genes encoding several DGC components disrupt the complex and lead to muscular dystrophy. Dystrobrevin alpha is a protein belongs to the dystrobrevin subfamily and the dystrophin family. This protein is a component of the dystrophin-associated protein complex (DPC). The DPC consists of dystrophin and several integral and peripheral membrane proteins, including dystroglycans, sarcoglycans, syntrophins and alpha- and beta-dystrobrevin. This protein may be involved in the formation and stability of synapses as well as the clustering of nicotinic acetylcholine receptors.
