Anti-PARC antibodies enable researchers to detect and measure the PARC antigen in biological samples. This target is a reported synonym of the CUL9 gene, which encodes cullin 9. This protein is known to function in cytoskeleton organization and protein ubiquitination, among other biological roles. The human version of PARC has a canonical amino acid length of 2517 residues and a protein mass of 281.2 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and notably expressed in many tissues, such as the endometrium, testis, and adrenal gland. PARC is a member of the Cullin protein family.
