Anti-PR domain 16 antibodies enable researchers to detect and measure the PR domain 16 antigen in biological samples. This target is a reported synonym of the PRDM16 gene, which encodes PR/SET domain 16. This protein is known to function in brown fat cell differentiation and the regulation of transcription, among other biological roles. The human version of PR domain 16 has a canonical amino acid length of 1276 residues and a protein mass of 140.3 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells. PR domain 16 is a member of the PRDM16 protein family.
