Anti-DMR antibodies enable researchers to detect and measure the DMR antigen in biological samples. This target is a reported synonym of the WDR20 gene, which encodes WD repeat domain 20. This protein is a reported regulator of deubiquitinating complexes. The human version of DMR has a canonical amino acid length of 569 residues and a protein mass of 62.9 kilodaltons, although 8 isoforms have been identified.
