Anti-C1orf164 antibodies enable researchers to detect and measure the C1orf164 antigen in biological samples. This target is a reported synonym of the RNF220 gene, which encodes ring finger protein 220. This protein is known to function in the Wnt signaling pathway and protein ubiquitination, among other biological roles. The human version of C1orf164 has a canonical amino acid length of 566 residues and a protein mass of 62.8 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in many tissues, such as the caudate, urinary bladder, and adrenal gland.
