Anti-PR domain 15 antibodies enable researchers to detect and measure the PR domain 15 antigen in biological samples. This target is a reported synonym of the PRDM15 gene, which encodes PR/SET domain 15. This protein is known to function in the Wnt signaling pathway and the regulation of transcription, among other biological roles. The human version of PR domain 15 has a canonical amino acid length of 1507 residues and a protein mass of 169.3 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the nucleus of cells. PR domain 15 is a member of the Class V-like SAM-binding methyltransferase protein superfamily.
