Summary: Predicted to enable isocitrate dehydrogenase (NAD+) activity. Predicted to be involved in isocitrate metabolic process and tricarboxylic acid cycle. Located in mitochondrion. Is expressed in several structures, including Malpighian tubule primordium; embryonic/larval midgut primordium; ganglia; gut section; and larval muscle cell. Used to study neuromuscular junction disease. Human ortholog(s) of this gene implicated in retinitis pigmentosa 90. Orthologous to human IDH3A (isocitrate dehydrogenase (NAD(+)) 3 catalytic subunit alpha). [provided by Alliance of Genome Resources, Dec 2024]
