Anti-RNF201 antibodies enable researchers to detect and measure the RNF201 antigen in biological samples. This target is a reported synonym of the RFWD3 gene, which encodes ring finger and WD repeat domain 3. This protein is known to function in DNA damage pathways and DNA repair, among other biological roles. The human version of RNF201 has a canonical amino acid length of 774 residues and a protein mass of 85.1 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in the skin, seminal vesicle, pancreas, kidney, and esophagus. This target antigen may also be known as FANCW.
