Anti-PET112L antibodies enable researchers to detect and measure the PET112L antigen in biological samples. This target is a reported synonym of the GATB gene, which encodes glutamyl-tRNA amidotransferase subunit B. This protein is known to function in mitochondrial translation, among other biological roles. The human version of PET112L has a canonical amino acid length of 557 residues and a protein mass of 61.9 kilodaltons. It is reported to be localized in the mitochondria of cells. Other names for this target antigen include COXPD41, HSPC199, and PET112.
