DYSF is identified as a component of a putative muscle-specific repair complex involved in the plasma membrane or muscle membrane repair machinery. In addition to patch repair, it also performs in the membrane trafficking via dysferlin-related signaling pathways in muscle cell. During repatching, it provides cell membrane scaffold like structure, which gives structural stability to muscle cells. Deficiency of dysferlin disrupts sarcolemmal membrane repair, termed as limb-girdle muscular dystrophies type 2B. Mutation in the gene also causes miyoshi myopathy.
