Anti-PR domain 5 antibodies enable researchers to detect and measure the PR domain 5 antigen in biological samples. This target is a reported synonym of the PRDM5 gene, which encodes PR/SET domain 5. This protein is known to function in chromatin organization and the cell cycle, among other biological roles. The human version of PR domain 5 has a canonical amino acid length of 630 residues and a protein mass of 73.1 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. PR domain 5 is a member of the Class V-like SAM-binding methyltransferase protein superfamily.
