Protein Information
Name CAV1
Synonyms CAV
Function May act as a scaffolding protein within caveolar membranes. Interacts directly with G-protein alpha subunits and can functionally regulate their activity (By similarity). Involved in the costimulatory signal essential for T-cell receptor (TCR)- mediated T-cell activation. Its binding to DPP4 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3- dependent manner. Recruits CTNNB1 to caveolar membranes and may regulate CTNNB1-mediated signaling through the Wnt pathway.
Cellular Location Golgi apparatus membrane; Peripheral membrane protein. Cell membrane; Peripheral membrane protein Membrane, caveola; Peripheral membrane protein. Membrane raft Note=Colocalized with DPP4 in membrane rafts. Potential hairpin- like structure in the membrane. Membrane protein of caveolae
Tissue Location Expressed in muscle and lung, less so in liver, brain and kidney

Caveolins make up a family of proteins that are principal structural components of hairpin-like domains in the plasma membrane (1). It is believed that caveolins serve as scaffolding proteins for the integration of signal transduction. Three members of caveolins (caveolin-1, -2 and -3) have been identified, possessing different tissue distributions (2). Caveolins interact with multiple signaling molecules, such as the G-protein alpha subunit (1), tyrosine kinase receptors, PKCs, Src family tyrosine kinases and eNOS (2,3). Caveolin-1 has been implicated in the pathogenesis of mammary epithelial cell hyperplasia (4). Endothelial cell (EC) migration is a critical event during multiple physiological and pathological processes. The phosphorylatable Tyr14 residue of caveolin-1 is required for polarization of the protein during transmigration but does not alter polarization during planar movement.
