IDH3A

Official Full Name

isocitrate dehydrogenase 3 (NAD+) alpha

Background

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.
