Gale UDP-galactose 4'-epimerase [Drosophila melanogaster (fruit fly)] - Gene

Summary

Official Full Name: UDP-galactose 4'-epimeraseprovided by FlyBase
Primary source: FLYBASE:FBgn0035147
Locus tag: Dmel_CG12030
See related: AllianceGenome:FB:FBgn0035147
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: CG12030; dGALE; Dmel\CG12030; GALE
Summary: Enables UDP-N-acetylglucosamine 4-epimerase activity and UDP-glucose 4-epimerase activity. Involved in galactose catabolic process via UDP-galactose; larval lymph gland hemopoiesis; and nucleotide-sugar metabolic process. Predicted to be active in cytosol. Is expressed in several structures, including adult head; embryonic/larval salivary gland; extraembryonic structure; gut section; and visceral mesoderm derivative. Used to study galactosemia. Human ortholog(s) of this gene implicated in galactose epimerase deficiency and thrombocytopenia. Orthologous to human GALE (UDP-galactose-4-epimerase).

What's a GeneRIF?

Our results demonstrate that both UDP-gal and UDP-galNAc activities of dGALE are required for Drosophila survival, although distinct roles for each activity can be seen in specific windows of developmental time or in response to a galactose challenge.
Title: UDP-galactose 4'-epimerase activities toward UDP-Gal and UDP-GalNAc play different roles in the development of Drosophila melanogaster.
Drosophila with partial GALE loss survive in the absence of galactose but succumb in development if exposed to dietary galactose.
Title: UDP-galactose 4' epimerase (GALE) is essential for development of Drosophila melanogaster.
