Isocitrate Dehydrogenase 1 (NADP+) human

Isocitrate dehydrogenase 1 (IDH1) gene is located on human chromosome 2q33. IDH1 is present in the cytoplasm and peroxisomes. It is expressed at high levels in the mammalian liver. IDH1 consists of a C-terminal tripeptide peroxisome, that targets the signal one sequence.

Isocitrate dehydrogenase 1 (IDH1) help in the oxidative carboxylation of isocitrate to α-ketoglutarate, that results in the formation of reduced nicotinamide adenine dinucleotide phosphate (NADPH). It participates in lipid metabolism and glucose sensing. Suppressing IDH1 in pancreatic islets affects the insulin secretion, induced by glucose and leads to increase in lactate production.

Supplied as a lyophilized powder containing Tris-HCl pH 8.0, trehalose, ammonium sulfate and DTT

One unit corresponds to the amount of enzyme which converts 1.0 μmol DL-isocitrate to α-ketoglutarate per minute at pH 7.4 and 37 °C (NADP as cofactor).
