Repairing the tears: dysferlin in muscle membrane repair

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 ). WebRecent findings suggest a crucial role for dysferlin in this repair process in muscle, possibly as a Ca(2+) sensor that triggers vesicle fusion.
