(redirected from Caveolins)


The 22-kD transmembrane protein associated with the membranes of caveolae and with Golgi membranes; believed to function in signal transduction, in cholesterol transport, and metabolism of the cell.

Caveolae are plasma membrane microdomains, composed by cholesterol, sphingolipids, and different coat proteins named caveolins, considered anchor points to molecules (in this context, insulin receptor and GLUT4), facilitating their interaction, in order to activate cell signaling and transport [91-93].

Caveolins like CAV2 and CAV3 act as scaffolding proteins within caveolar membranes that interact directly with G-protein alpha subunits and can functionally regulate their activity.
Caveolae consist of scaffolding proteins called caveolins. Caveolins are a 21 to 24kDa family of membrane proteins that consist of three members; caveolin-1 (CAV-1) is abundantly expressed in endothelial cells, and caveolin-3 (CAV-3) is primarily expressed in muscle cells [16].
Caveolins and flotillins are two families of the membrane proteins correlating with Caveolae of the mammals (Bickel et al., 1997).
Basal-Like Subtypes.--These tumors express basal/ myoepithelial cell genes, such as CK5, CK14, CK17, caveolins 1 and 2, nestin, P-cadherin, CD44, and EGFR.

Caveolae are characterized by expression of Caveolins (Cav-1, -2, and -3), a class of transmembrane proteins (21-24 kDa) that are essential for caveolae formation [17,18].
