Anti-Cavin antibodies enable researchers to detect and measure the Cavin antigen in biological samples. This target is a reported synonym of the CAVIN1 gene, which encodes caveolae associated protein 1. This protein is known to play an important role in caveolae formation and organization. The human version of Cavin has a canonical amino acid length of 390 residues and a protein mass of 43.5 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane, nucleus, mitochondria, ER, and cytoplasm of cells and notably expressed in many tissues, such as in adipose tissue and breast. Cavin is a member of the CAVIN protein family.
