Anti-SAM-dependent methyltransferase antibodies enable researchers to detect and measure the SAM-dependent methyltransferase antigen in biological samples. This target is a reported synonym of the THUMPD2 gene, which encodes THUMP domain containing 2. The human version of SAM-dependent methyltransferase has a canonical amino acid length of 503 residues and a protein mass of 56.4 kilodaltons, although 2 isoforms have been identified. It is reported to be widely expressed in many tissue types. Other names for this target antigen include THUMP domain-containing protein 2 and SAM-dependent methyltransferase.
