The protein encoded by this gene is a major component of the inner surface of caveolae, small invaginations of the plasma membrane, and is involved in essential cellular functions, including signal transduction, lipid metabolism, cellular growth control and apoptosis. This protein may function as a tumor suppressor. This gene and related family member (CAV1) are located next to each other on chromosome 7, and express colocalizing proteins that form a stable hetero-oligomeric complex. Alternatively spliced transcript variants encoding different isoforms have been identified for this gene. Additional isoforms resulting from the use of alternate in-frame translation initiation codons have also been described, and shown to have preferential localization in the cell (PMID:11238462).

Forensic Context
A systematic review of postmortem human brain studies found that the CAV2 mRNA, a connexin-binding partner, exhibited decreased transcription in the anterior cingulate cortex of individuals who died by suicide compared to controls [Yamamoto et al. DOI:10.3390/Ijms25115750].
