IDH3A Antibody / Isocitrate dehydrogenase [NAD] subunit alpha

Isocitrate dehydrogenase [NAD] subunit alpha, mitochondrial (IDH3?) is an enzyme that in humans is encoded by the IDH3A gene. Isocitrate dehydrogenases catalyze the oxidative decarboxylation of isocitrate to 2-oxoglutarate. These enzymes belong to two distinct subclasses, one of which utilizes NAD (+) as the electron acceptor and the other NADP (+) . Five isocitrate dehydrogenases have been reported: three NAD (+) -dependent isocitrate dehydrogenases, which localize to the mitochondrial matrix, and two NADP (+) -dependent isocitrate dehydrogenases, one of which is mitochondrial and the other predominantly cytosolic. NAD (+) -dependent isocitrate dehydrogenases catalyze the allosterically regulated rate-limiting step of the tricarboxylic acid cycle. Each isozyme is a heterotetramer that is composed of two alpha subunits, one beta subunit, and one gamma subunit. The protein encoded by this gene is the alpha subunit of one isozyme of NAD (+) -dependent isocitrate dehydrogenase.
