Anti-FJH1 antibodies enable researchers to detect and measure the FJH1 antigen in biological samples. This target is a reported synonym of the MRM2 gene, which encodes mitochondrial rRNA methyltransferase 2. This protein is known to function in rRNA processing, among other biological roles. The human version of FJH1 has a canonical amino acid length of 246 residues and a protein mass of 27.4 kilodaltons. It is reported to be localized in the mitochondria of cells. Other names for this target antigen include FTSJ2 and HEL97.
