PROTEIN NAME

Caveolin-1

SYNONYMS

BSCL3 antibody; CAV antibody; CAV1 antibody; CAV1_HUMAN antibody; caveolae protein, 22 kD antibody; caveolin 1 alpha isoform antibody; caveolin 1 beta isoform antibody; Caveolin 1 caveolae protein 22kDa antibody; Caveolin-1 antibody; Caveolin1 antibody; cell growth-inhibiting protein 32 antibody; CGL3 antibody; LCCNS antibody; MSTP085 antibody; OTTHUMP00000025031 antibody; PPH3 antibody; VIP 21 antibody; VIP21 antibody

SEQUENCE SIMILARITIES

Belongs to the caveolin family.

TISSUE SPECIFICITY

Skeletal muscle, liver, stomach, lung, kidney and heart (at protein level). Expressed in the brain.

POST-TRANSLATIONAL MODIFICATION

Ubiquitinated. Undergo monoubiquitination and multi- and/or polyubiquitination. Monoubiquitination of N-terminal lysines promotes integration in a ternary complex with UBXN6 and VCP which promotes oligomeric CAV1 targeting to lysosomes for degradation.; The initiator methionine for isoform 2 is removed during or just after translation. The new N-terminal amino acid is then N-acetylated.; Phosphorylated at Tyr-14 by ABL1 in response to oxidative stress.

SUBCELLULAR LOCATION

Cell membrane

FUNCTION

Caveolin, an integral membrane protein, is a principal component of caveolae membranes in vivo. Two isoforms of caveolin have been identified: a slower migrating 24-kDa species (-isoform) and a faster migrating 21-kDa species (-isoform). Caveolins interact with multiple signaling molecules, such as the G-protein alpha subunit, tyrosine kinase receptors, PKCs, Src family tyrosine kinases and eNOS. Caveolin-1 has been implicated in the pathogenesis of mammary epithelial cell hyperplasia.
