ICC 1/100.
WB 1/1000 - 1/10000. Predicted molecular weight: 20 kDa.
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function
      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.
    • Tissue specificity
      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.
    • Sequence similarities
      Belongs to the caveolin family.
    • Post-translational
      The initiator methionine for isoform Beta is removed during or just after translation. The new N-terminal amino acid is then N-acetylated.
    • Cellular localization
      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.

    • Anti-Caveolin-1 antibody [E249] - Caveolae Marker (ab32577) + A431 cell lysate

      Predicted band size: 20 kDa
      Observed band size: 23 kDa (why is the actual band size different from the predicted?)
      Additional bands at: 22 kDa. We are unsure as to the identity of these extra bands.

    • Immunocytochemistry/Immunofluorescence analysis of A431 cells labelling Caveolin-1 (green) with ab32577 at 1/200. Cells were fixed with 100% methanol. ab150077, an Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody. The cells were co-stained with ab195889 (red), an Alexa Fluor® 488 conjugated mouse anti-tubulin antibody (1/200). Nuclei counterstained with DAPI (blue).

    • Immunohistochemical analysis of formalin-fixed, paraffin-embedded Human urinary bladder tissue, staining Caveolin-1 with ab32577 at 1/250 dilution.

    • Immunohistochemical analysis of formalin-fixed, paraffin-embedded Human lung tissue, staining Caveolin-1 with ab32577 at 1/250 µg/ml.

    • Immunohistochemical analysis of developing Human lung tissue, staining Caveolin-1 with ab32577 at 1/250 dilution.
