Anti-MST077 antibodies enable researchers to detect and measure the MST077 antigen in biological samples. This target is a reported synonym of the NSUN3 gene, which encodes NOP2/Sun RNA methyltransferase 3. The human version of MST077 has a canonical amino acid length of 340 residues and a protein mass of 38.2 kilodaltons. It is reported to be localized in the mitochondria of cells. MST077 is a member of the RsmB/NOP protein family.
