- IDH2
Isocitrate dehydrogenase 2 (NADP+), mitochondrial, also known as IDH2, is a human
gene .cite web | title = Entrez Gene: IDH2 isocitrate dehydrogenase 2 (NADP+), mitochondrial| url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=3418| accessdate = ]Isocitrate dehydrogenase s areenzyme s that catalyze the oxidativedecarboxylation ofisocitrate to2-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 themitochondrial matrix , and two NADP(+)-dependent isocitrate dehydrogenases, one of which is mitochondrial and the other predominantly cytosolic. Each NADP(+)-dependent isozyme is ahomodimer . The protein encoded by the IDH2 gene is the NADP(+)-dependent isocitrate dehydrogenase found in the mitochondria. It plays a role in intermediary metabolism and energy production. This protein may tightly associate or interact with thepyruvate dehydrogenase complex .cite web | title = Entrez Gene: IDH2 isocitrate dehydrogenase 2 (NADP+), mitochondrial| url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=3418| accessdate = ]References
