The gene Aldehyde dehydrogenase is referred to in FlyBase by the symbol Dmel\Aldh (CG3752, FBgn0012036). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: aldehyde dehydrogenase (NAD) activity; acetaldehyde dehydrogenase (acetylating) activity. There is experimental evidence that it is involved in the biological process: response to ethanol; acetaldehyde metabolic process. 12 alleles are reported. The phenotype of these alleles is annotated with: trichogen cell. It has 2 annotated transcripts and 2 annotated polypeptides. Protein features are: Aldehyde dehydrogenase domain; Aldehyde dehydrogenase, C-terminal; Aldehyde dehydrogenase, N-terminal; Aldehyde dehydrogenase, conserved site; Aldehyde/histidinol dehydrogenase. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of low expression. Peak expression observed within 00-06 and 12-24 hour embryonic stages, at stages throughout the larval period, in stages of adults of both sexes. Summary of FlyAtlas Anatomical Expression Data: High levels of expression observed in all larval and adult organs/tissues. Expression at high levels in the following post-embryonic organs or tissues: adult head, adult eye, larval/adult central nervous system, adult crop, larval/adult midgut, larval/adult hindgut, larval/adult Malpighian tubules, adult heart, larval/adult fat body, larval/adult salivary gland, larval trachea, adult female reproductive system, adult male reproductive system, larval/adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1634096_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of Aldh. Gene sequence location is 2L:9387389..9391567.

Results are opposed to those of Lietaert, Experientia 38:651 and Lietaert, Experientia 41:57, who concluded that the ALDH activity was mainly in the mitochondria.
Subcellular localization of the aldehyde dehydrogenase activity from the ALDH enzyme was studied in wild type and Adhn4 adults. Aldehyde dehydrogenase activities from Adh and Aldh gene products are selectively inhibited by cyanimide or acetone, respectively. Contrary to the situation in larvae, in adults the ALDH activity from the Aldh gene product is mainly in the cytosolic, as opposed to the mitochondrial, fraction. Although larvae and adults use different ALDH activities to detoxify acetaldehyde (from Adh and Aldh encoded enzymes, respectively) both activities are cytosolic.
In adults, as opposed to larvae, acetaldehyde is mainly oxidised into acetate by means of Aldh enzymes. The reducing activity of the Adh enzyme, which transforms acetaldehyde into ethanol, also plays an essential role in the detoxification of acetaldehyde.
Aldh gene product is present in larvae but the activity of this enzyme differs from the ALDH activity of the Adh gene product. Studies of the flux of ethanol into lipid suggested that more than 75% of the oxidation of acetaldehyde in wild type larvae is catalysed by Adh product.
