Functioni

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. May act as a scaffolding protein within caveolar membranes. Interacts directly with G-protein alpha subunits and can functionally regulate their activity. Forms a stable heterooligomeric complex with CAV2 that targets to lipid rafts and drives caveolae formation. Recruits CTNNB1 to caveolar membranes and may regulate CTNNB1-mediated signaling through the Wnt pathway. Negatively regulates TGFB1-mediated activation of SMAD2/3 by mediating the internalization of TGFBR1 from membrane rafts leading to its subsequent degradation.Mediates the recruitment of CAVIN proteins (CAVIN1/2/3/4) to the caveolae.By similarity

Post-translational modificationi

Phosphorylation of isoform Beta on serine residues is constitutive. Phosphorylated at Tyr-14 by ABL1 in response to oxidative stress (By similarity).By similarity
Ubiquitinated. Undergo monoubiquitination and multi- and/or polyubiquitination. Monoubiquitination of N-terminal lysines promotes integration in a ternary complex with UBXN6 and VCP which promotes oligomeric CAV1 targeting to lysosomes for degradation.By similarity
