Summary: Enables malate dehydrogenase (decarboxylating) (NADP+) activity. Involved in several processes, including determination of adult lifespan; malate metabolic process; and nicotinamide nucleotide metabolic process. Located in cytosol. Is expressed in several structures, including adult brain cell body rind; brain; embryonic/larval hemocyte; germline cell; and somatic precursor cell. Orthologous to several human genes including ME1 (malic enzyme 1). [provided by Alliance of Genome Resources, Dec 2024]

Studies suggest that variation in levels of cytoplasmic malic enzyme may contribute to variation in alcohol consumption.
Title: Alcohol sensitivity in Drosophila: translational potential of systems genetics.
Malic Enzyme is regulated by juvenile hormone by two mechanisms. One is by a direct effect of JH on the enzyme. The other is by stimulation of transcription of the MEN gene.
