Anti-COXPD15 antibodies enable researchers to detect and measure the COXPD15 antigen in biological samples. This target is a reported synonym of the MTFMT gene, which encodes mitochondrial methionyl-tRNA formyltransferase. This protein is reported to be a Methionyl-tRNA formyltransferase that formylates methionyl-tRNA in mitochondria and is crucial for translation initiation. The human version of COXPD15 has a canonical amino acid length of 389 residues and a protein mass of 43.8 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the mitochondria of cells. COXPD15 is a member of the Fmt protein family.
