M-caveolin, a muscle-specific caveolin-related protein.
Caveolae, small invaginations of the plasma membrane, are a characteristic feature of many mammalian cells. The best-characterised caveolar protein is the integral membrane protein, VIP21-caveolin. We now describe a novel homologue of VIP21-caveolin, M-caveolin, which is expressed exclusively in muscle. M-caveolin was shown to be expressed in differentiated myotubes but not myoblasts. Epitope-t...
متن کاملIdentification of caveolin and caveolin-related proteins in the brain.
Caveolae are 50-100 nm, nonclathrin-coated, flask-shaped plasma membrane microdomains that have been identified in most mammalian cell types, except lymphocytes and neurons. To date, multiple functions have been ascribed to caveolae, including the compartmentalization of lipid and protein components that function in transmembrane signaling events, biosynthetic transport functions, endocytosis, ...
متن کاملCaveolin regulates endocytosis of the muscle repair protein, dysferlin.
Dysferlin and Caveolin-3 are plasma membrane proteins associated with muscular dystrophy. Patients with mutations in the CAV3 gene show dysferlin mislocalization in muscle cells. By utilizing caveolin-null cells, expression of caveolin mutants, and different mutants of dysferlin, we have dissected the site of action of caveolin with respect to dysferlin trafficking pathways. We now show that Ca...
متن کاملZebrafish as a model for caveolin-associated muscle disease; caveolin-3 is required for myofibril organization and muscle cell patterning.
Caveolae are an abundant feature of many animal cells. However, the exact function of caveolae remains unclear. We have used the zebrafish, Danio rerio, as a system to understand caveolae function focusing on the muscle-specific caveolar protein, caveolin-3 (Cav3). We have identified caveolin-1 (alpha and beta), caveolin-2 and Cav3 in the zebrafish. Zebrafish Cav3 has 72% identity to human CAV3...
متن کاملTwo distinct caveolin-1 domains mediate the functional interaction of caveolin-1 with protein kinase A.
Numerous components of the cAMP-based signaling cascade, namely G-proteins and G- protein coupled receptors, adenylyl cyclase, and protein kinase A (PKA) have been localized to caveolae and shown to be regulated by the caveolar marker proteins, the caveolins. In order to gain mechanistic insights into these processes in vivo, we have assessed the functional interaction of caveolin-1 (Cav-1) wit...
