epitope mapping within an internal region of ND4 of human origin
recommended for detection of NADH-ubiquinone oxidoreductase chain 4 of mouse, rat and human origin by WB, IF and ELISA; also reactive with additional species, including equine, canine, bovine and porcine
ND4 Background Information NADH:ubiquinone oxidoreductase (complex I) is an extremely complicated multiprotein complex located in the inner mitochondrial membrane. Human complex I is important for energy metabolism because its main function is to transport electrons from NADH to ubiquinone, which is accompanied by trans-location of protons from the mitochondrial matrix to the intermembrane space. Human complex I appears to consist of 41 subunits. A small number of complex I subunits are the products of mitochondrial genes (subunits 1-7), while the remainder are nuclear encoded and imported from the cytoplasm. NADH dehydrogenase subunit 4 (ND4) is most likely a component of the hydrophobic protein fragment of complex I. Mutations in the gene encodiing for ND4 are implicated in Leber hereditary optic neuropathy, a rare condition that can cause loss of central vision.
