Summary: 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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

NM_001206747.2 → NP_001193676.1 caveolin-2 isoform b

Status: REVIEWED

Description

Transcript Variant: This variant (1) encodes two isoforms resulting from the use of alternate in-frame, translation initiation codons. This RefSeq represents the shorter isoform (b, also known as beta) derived from the use of the downstream AUG (at nt 221-223). Isoform beta has been shown to localize almost exclusively in lipid droplets (PMID:11238462).

Transcript Variant: This variant (1) encodes two isoforms resulting from the use of alternate in-frame, translation initiation codons. This RefSeq represents the longer isoform (a, also known as alpha) derived from the use of the upstream AUG (at nt 182-184). Isoform alpha has been shown to localize mostly in the golgi (PMID:11238462).
