General description

Caveolin-2 is an isoform of caveolin, an integral transmembrane protein of the caveolae membranes. It has a molar mass of 20-22 kDa and is a major coat protein found in caveolae of most cell types. It exists as two isoforms α and β due to alternative splicing of the respective mRNAs. Caveolin-2α corresponds to the full-length protein (20 kDa, 162 amino acids), whereas caveolin-2β isoform lacks a 13 amino acid sequence at its N-terminus.

Immunogen

synthetic peptide corresponding to amino acids 1-20 located at the N-terminus of mouse caveolin-2, conjugated to KLH. This sequece is identical in rat caveolin-2, highly conserved (90% identity) in human, dog, and pig caveolin-2, and is not found in caveolin-1 and caveolin-3.

Biochem/physiol Actions

Caveolin-2 colocalizes and forms a hetero-oligomeric complex with caveolin-1 in vivo. Caveolins family members function as scaffolding proteins to organize and concentrate specific lipids such as cholesterol and glycosylphosphatidylinositol (GPI) and lipid modified signaling molecules within caveolae membranes. Caveolin-2 is phosphorylated on Ser23 and Ser36 and modulates caveolin-1-dependent caveola formation.

Physical form

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