Anti-C9orf156 antibodies enable researchers to detect and measure the C9orf156 antigen in biological samples. This target is a reported synonym of the TRMO gene, which encodes tRNA methyltransferase O. The human version of C9orf156 has a canonical amino acid length of 441 residues and a protein mass of 48.6 kilodaltons. It is reported to be notably expressed in many tissues, such as the adrenal gland and pancreas. C9orf156 is a member of the TRNA methyltransferase O protein family.
