Caveolin 2

Caveolin-2 is a is_associated_with::protein that in humans is encoded by the CAV2 is_associated_with::gene.

The is_associated_with::protein encoded by this is_associated_with::gene is a major component of the inner surface of is_associated_with::caveolae, small invaginations of the plasma membrane, and is involved in essential cellular functions, including signal transduction, lipid metabolism, cellular growth control and is_associated_with::apoptosis. This protein may function as a is_associated_with::tumor suppressor. CAV1 and CAV2 are located next to each other on is_associated_with::chromosome 7 and express colocalizing proteins that form a stable hetero-oligomeric complex. Two transcript variants encoding distinct isoforms have been identified for this gene. By using alternative initiation is_associated_with::codons in the same reading frame, two isoforms (alpha and beta) are encoded by one transcript.

Interactions
Caveolin 2 has been shown to interact with is_associated_with::Caveolin 1 and is_associated_with::RAS p21 protein activator 1.
