Protein Information (annotations from UniProt)

Database IDHIV0008194
UniProt IDP51636
Primary gene name(s)CAV2
Synonym gene name(s)unknown
Protein nameCaveolin-2
Protein functionMay act as a scaffolding protein within caveolar membranes. Interacts directly with G-protein alpha subunits and can functionally regulate their activity. Acts as an accessory protein in conjunction with CAV1 in targeting to lipid rafts and driving caveolae formation. The Ser-36 phosphorylated form has a role in modulating mitosis in endothelial cells. Positive regulator of cellular mitogenesis of the MAPK signaling pathway. Required for the insulin-stimulated nuclear translocation and activation of MAPK1 and STAT3, and the subsequent regulation of cell cycle progression, By similarity. {ECO:0000250, ECO:0000269|PubMed:15504032, ECO:0000269|PubMed:18081315}.
Subcellular locationNucleus. Cytoplasm. Golgi apparatus membrane;
Peripheral membrane protein. Cell membrane;
Peripheral membrane protein. Membrane, caveola;
Peripheral membrane protein. Note=Potential hairpin-like structure in the membrane. Membrane protein of caveolae. Tyr-19-phosphorylated form is enriched at sites of cell-cell contact and is translocated to the nucleus in complex with MAPK1 in response to insulin, By similarity. Tyr-27-phosphorylated form is located both in the cytoplasm and plasma membrane. CAV1-mediated Ser-23-phosphorylated form locates to the plasma membrane. Ser-36-phosphorylated form resides in intracellular compartments. {ECO:0000250}.
