IDH1 Rabbit Polyclonal Antibody

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. Each NADP (+) -dependent isozyme is a homodimer. The protein encoded by this gene is the NADP (+) -dependent isocitrate dehydrogenase found in the cytoplasm and peroxisomes. It contains the PTS-1 peroxisomal targeting signal sequence. The presence of this enzyme in peroxisomes suggests roles in the regeneration of NADPH for intraperoxisomal reductions, such as the conversion of 2, 4-dienoyl-CoAs tocatalytic activity:Isocitrate + NADP (+) = 2-oxoglutarate + CO (2) + NADPH., catalytic activity:Oxalosuccinate + NADP (+) = 2-oxoglutarate + CO (2) + NADPH., cofactor:Binds 1 magnesium or manganese ion per subunit., disease:Defects in IDH1 are a cause of glioblastoma multiforme (GBM) [MIM:137800]; also called familial glioma of brain. Gliomas are central nervous system neoplasms derived from glial cells and comprise astrocytomas, glioblastoma multiforme, oligodendrogliomas, and ependymomas., miscellaneous:Cancer mutations affecting Arg-132 are tissue-specific, and suggest that this residue plays a unique role in the development of high-grade gliomas., online information:Isocitrate dehydrogenase entry, similarity:Belongs to the isocitrate and isopropylmalate dehydrogenases family., subunit:Homodimer.
