WebDysferlin is a membrane-associated protein implicated in sarcolemmal repair and also linked to other membrane functions including the maintenance of transverse tubules in muscle. MG53, annexins, and Eps15-homology domain (EHD)-containing proteins interact with dysferlin to form a membrane repair complex and similarly have roles in … WebMembrane repair is a critical mechanism for cell survival, and well-characterized proteins such as MG53 and dysferlin have been implicated in the resealing of human and mouse muscle plasma membrane. MG53 and dysferlin accumulate at the site of membrane damage in muscle fibers ( Bansal et al., 2003 ; Cai et al., 2009 ; Marg et al., 2012 ).
