RefSeq status: REVIEWED
Organism: Drosophila melanogaster
Lineage: Eukaryota; Metazoa; Ecdysozoa; Arthropoda; Hexapoda; Insecta; Pterygota; Neoptera; Endopterygota; Diptera; Brachycera; Muscomorpha; Ephydroidea; Drosophilidae; Drosophila; Sophophora
Also known as: CG9122; CT9937; Dmel\CG9122; dTrh; DTRH; DTRHn; trh; Trh; TrH; TRH; TRHn
Summary: Enables phenylalanine 4-monooxygenase activity and tryptophan 5-monooxygenase activity. Involved in several processes, including regulation of circadian sleep/wake cycle, sleep; serotonin biosynthetic process from tryptophan; and tracheal pit formation in open tracheal system. Predicted to be active in neuron projection. Is expressed in several structures, including CNS neuron; adult abdomen; brain; serotonergic neurons; and synaptic neuropil domain. Used to study autism spectrum disorder. Human ortholog(s) of this gene implicated in several diseases, including alcohol use disorder; attention deficit hyperactivity disorder; autistic disorder; borderline personality disorder; and depressive disorder (multiple). Orthologous to several human genes including TPH1 (tryptophan hydroxylase 1). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

DTRH may be primarily neuronal in function and expression, and serve as an ancient conserved mechanism to appropriately regulate the production of serotonin in its target tissues.
