General description

Caveolin, a 20-24 kDa integral transmembrane protein, has been identified as a principal component of caveolae membranes. Caveolin (also termed VIP21) exists in several isoforms termed caveolin-1, caveolin-2 and caveolin-3. Caveolin-1 (CAV1) (20- 22 kDa) can exist as two isoforms, caveolin-1α and -1β due to alternative splicing of the mRNA. Caveolin-1 and -2 have similar tissue distribution.

Specificity

The sequence is highly conserved in many species, e.g., identical in rat, mouse, bovine, and dog caveolin-1. The sequence is not found in caveolin-2 or caveolin-3.

Immunogen

synthetic peptide corresponding to a region at the N-terminus of human caveolin-1 (amino acids 2-20).

Application

Anti-Caveolin-1 antibody produced in rabbit has been used in:
  • immunoblotting
  • immunofluorescence
  • immunohistochemistry

Biochem/physiol Actions

Caveolin can simultaneously recognize GPI-linked proteins and interact directly with a number of caveolae associated downstream signaling molecules, such as H-Ras, hetero-trimeric G-proteins, annexin-II, epidermal growth factor receptor (EGFR), protein kinase C, src-family tyrosine kinases and nitric oxide synthase (NOS) isoforms. Caveolin-1 participates in angiogenesis and is expected to play a major role in the growth and evolution of cancer. It participates in glucose metabolism by controlling the expression of glucose transporters.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Endothelial microvesicles (EMVs), released after endothelial cell (EC) apoptosis or activation, may carry many adverse signals and propagate injury by intercellular transmission. Caveolae are 50-100 nm cell surface plasma membrane invaginations involved in many pathophysiological processes. Recent evidence has indicated EMVs...
