Anti-ATP synthase, H+ transporting, mitochondrial F1 complex, epsilon subunit antibodies enable researchers to detect and measure the ATP synthase, H+ transporting, mitochondrial F1 complex, epsilon subunit antigen in biological samples. This target is a reported synonym of the ATP5F1E gene, which encodes ATP synthase F1 subunit epsilon. The human version of ATP synthase, H+ transporting, mitochondrial F1 complex, epsilon subunit has a canonical amino acid length of 51 residues and a protein mass of 5.8 kilodaltons. It is reported to be localized in the mitochondria of cells. Other names for this target antigen include ATP5E, ATPE, and MC5DN3.
