应用说明Is unsuitable for Flow Cyt,ICC/IF,IHC-P or IP.
功能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.
组织特异性Expressed in muscle and lung, less so in liver, brain and kidney.
疾病相关Defects in CAV1 are the cause of congenital generalized lipodystrophy type 3 (CGL3) [MIM:612526]; also called Berardinelli-Seip congenital lipodystrophy type 3 (BSCL3). Congenital generalized lipodystrophies are autosomal recessive disorders characterized by a near absence of adipose tissue, extreme insulin resistance, hypertriglyceridemia, hepatic steatosis and early onset of diabetes.
序列相似性Belongs to the caveolin family.
翻译后修饰The initiator methionine for isoform Beta is removed during or just after translation. The new N-terminal amino acid is then N-acetylated.
细胞定位Golgi apparatus membrane. Cell membrane. Membrane > caveola. Membrane raft. Colocalized with DPP4 in membrane rafts. Potential hairpin-like structure in the membrane. Membrane protein of caveolae.
Dot Blot - Anti-Caveolin-1 (phospho Y14) antibody [EPR2288Y] (ab75876)
Dot blot analysis of Caveolin-1 (phospho Y14) phospho peptide (Lane 1), Caveolin-1 Non-phospho peptide (Lane 2) labelling Caveolin-1 (phospho Y14) with ab75876 at a dilution of 1/1000. Peroxidase conjugated goat anti-rabbit IgG (H+L)) was used as the secondary antibody at a dilution of 1/2500.
