Dysferlin and muscle membrane repair
WebAug 1, 2003 · In support of a role for dysferlin in membrane fusion, electron micrographs from dysferlin-mutant muscle showed an increased number of sub-sarcolemmal … 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 ).

Did you know?
Webestablishing the function of dysferlin in muscle membrane repair [1,2,3,15], little is known about how dysferlin exerts its function. Dysferlin is a 230 kDa type II transmembrane protein, belonging to the ferlin-1-like protein family [9,16]. All ferlin-1-like proteins contain multiple C2 domains that were known to possess the WebDec 21, 2024 · Dysferlinopathies are a clinically heterogeneous group of muscular dystrophies caused by a genetic deficiency of the membrane-associated protein dysferlin, which usually manifest post-growth in young adults. The disease is characterized by progressive skeletal muscle wasting in the limb-girdle and limbs, inflammation, …
WebMay 8, 2003 · To see if these vesicles could participate in membrane repair, Bansal et al. isolated muscle fibres from wild-type, mdx and dysferlin-null mice, exposed them to laser-induced membrane damage, and ... WebJun 5, 2007 · Dysferlin is the first identified member of a putative muscle-specific repair complex that permits rapid resealing of membranes disrupted by mechanical stress. Membrane resealing is a function conserved by most cells and is mediated by a mechanism closely resembling regulated, Ca2+-dependent exocytosis.
