Gene Gene information from NCBI Gene database.
Entrez ID 3418
Gene name Isocitrate dehydrogenase (NADP(+)) 2
Gene symbol IDH2
Synonyms (NCBI Gene)
D2HGA2ICD-MIDHIDH-2IDHMIDPIDPMmNADP-IDH
Chromosome 15
Chromosome location 15q26.1
Summary 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
