Official Full Name: Mitochondrial trifunctional protein beta subunitprovided by FlyBase
Primary source: FLYBASE:FBgn0025352
Locus tag: Dmel_CG4581
See related: AllianceGenome:FB:FBgn0025352
Gene type: protein coding
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: ACoT; CG4581; dHADHB; Dmel\CG4581; l(2)k09828; MTP; thiolase; Thiolase
Summary: Predicted to enable acyltransferase activity, transferring groups other than amino-acyl groups. Involved in determination of adult lifespan and fatty acid beta-oxidation. Located in mitochondrion. Is expressed in several structures, including adult heart; embryonic dorsal epidermis; embryonic/larval fat body; germline cell; and gut section. Used to study fatty liver disease; lipid metabolism disorder; and mitochondrial trifunctional protein deficiency. Human ortholog(s) of this gene implicated in mitochondrial metabolism disease and mitochondrial trifunctional protein deficiency. Orthologous to human HADHB (hydroxyacyl-CoA dehydrogenase trifunctional multienzyme complex subunit beta). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

both Mtpalpha(KO) and Mtpbeta(KO) flies were impaired in long-chain fatty acid beta-oxidation; results strongly suggest that the functions of MTP are essentially conserved between mammals and Drosophila [Mtpalpha][Mtpbeta]
