Anti-Mrf1 antibodies enable researchers to detect and measure the Mrf1 antigen in biological samples. This target is a reported synonym of the MTRF1 gene, which encodes mitochondrial translation release factor 1. The human version of Mrf1 has a canonical amino acid length of 445 residues and a protein mass of 52.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the mitochondria of cells. Mrf1 is a member of the Prokaryotic/mitochondrial release factor protein family.
