Use at an assay dependent concentration.
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.
Expressed in muscle and lung, less so in liver, brain and kidney.
Involvement in disease
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.
Belongs to the caveolin family.
The initiator methionine for isoform Beta is removed during or just after translation. The new N-terminal amino acid is then N-acetylated.
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.

ab17052 staining Caveolin-1 in human Hacat keratinocyte cells by Immunocytochemistry/ Immunofluorescence. The cells were formaldehyde fixed, permeabilised in 0.1% Triton X-100 and then blocked using 1% serum for 1 hour at 25°C. Samples were then incubated with primary antibody at 1/75 for 24 hours at 4°C. The secondary antibody used was conjugated to Alexa Fluor® 488 (green) used at a 1/500 dilution.
Overlay histogram showing CHO cells stained with ab17052 (red line). The cells were fixed with methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab17052, 0.5µg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a significantly decreased signal in CHO cells fixed with 4% paraformaldehyde (10 min) used under the same conditions.
Please note that Abcam do not have data for use of this antibody on non-fixed cells. We welcome any customer feedback.
