DESCRIPTION
Also known as CAV2_SHEEP, CAV2. May 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. 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). Monomer or homodimer (By similarity). Interacts with CAV1; the interaction forms a stable heterooligomeric complex that is required for targeting to lipid rafts and for caveolae formation. Tyrosine phosphorylated forms do not form heterooligomers with the Tyr-19-phosphorylated form existing as a monomer or dimer, and the Tyr-27-form as a monomer only. Interacts (tyrosine phosphorylated form) with the SH2 domain-containing proteins, RASA1, NCK1 and SRC. Interacts (tyrosine phosphorylated form) with INSR, the interaction (Tyr-27-phosphorylated form) is increased on insulin stimulation. Interacts (Tyr-19 phosphorylated form) with MAPK1 (phosphorylated form); the interaction, promoted by insulin, leads to nuclear location and MAPK1 activation. Interacts with STAT3; the interaction is increased on insulin-induced tyrosine phosphorylation leading to STAT activation (By similarity).
