Anti-Caveolin-1 antibody produced in rabbit，200UL，C4490-200UL，Sigma

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.

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.
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.
