Anti-PR domain 2 antibodies enable researchers to detect and measure the PR domain 2 antigen in biological samples. This target is a reported synonym of the PRDM2 gene, which encodes PR/SET domain 2. This protein is known to function in the regulation of transcription, among other biological roles. The human version of PR domain 2 has a canonical amino acid length of 1718 residues and a protein mass of 188.9 kilodaltons. It is reported to be localized in the nucleus of cells and notably expressed in many tissues, such as the caudate and cerebral cortex. PR domain 2 is a member of the Class V-like SAM-binding methyltransferase protein superfamily.
