Anti-PR domain 8 antibodies enable researchers to detect and measure the PR domain 8 antigen in biological samples. This target is a reported synonym of the PRDM8 gene, which encodes PR/SET domain 8. This protein is known to function in the regulation of transcription, among other biological roles. The human version of PR domain 8 has a canonical amino acid length of 689 residues and a protein mass of 71.7 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. PR domain 8 is a member of the Class V-like SAM-binding methyltransferase protein superfamily.
