Anti-PR domain 13 antibodies enable researchers to detect and measure the PR domain 13 antigen in biological samples. This target is a reported synonym of the PRDM13 gene, which encodes PR/SET domain 13. This protein is known to function in the differentiation of certain cell types, among other biological roles. The human version of PR domain 13 has a canonical amino acid length of 707 residues and a protein mass of 74 kilodaltons. It is reported to be localized in the nucleus of cells. PR domain 13 is a member of the Class V-like SAM-binding methyltransferase protein superfamily.
