Xpd Xeroderma pigmentosum D [Drosophila melanogaster (fruit fly)] - Gene

Summary

Official Symbol: Xpdprovided by FlyBase
Official Full Name: Xeroderma pigmentosum Dprovided by FlyBase
Primary source: FLYBASE:FBgn0261850
Locus tag: Dmel_CG9433
See related: AllianceGenome:FB:FBgn0261850
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: CG9433; DhR3; DhXPD; Dmel\CG9433; DmXPD; ERCC2; l(2)SH2 2137; l(2)SH2137; xpd; XPD; XPD/ERCC2
Summary: Predicted to enable 5'-3' DNA helicase activity and damaged DNA binding activity. Involved in several processes, including regulation of chromosome segregation; regulation of mitotic cell cycle; and response to UV. Located in cytoplasm; nucleus; and polytene chromosome. Part of transcription factor TFIIH core complex and transcription factor TFIIH holo complex. Is expressed in embryonic cortex; embryonic/larval fat body; embryonic/larval salivary gland; and organism. Used to study Cockayne syndrome; photosensitive trichothiodystrophy; and xeroderma pigmentosum. Human ortholog(s) of this gene implicated in several diseases, including acoustic neuroma; acquired immunodeficiency syndrome; carcinoma (multiple); hematologic cancer (multiple); and xeroderma pigmentosum (multiple). Orthologous to human ERCC2 (ERCC excision repair 2, TFIIH core complex helicase subunit). [provided by Alliance of Genome Resources, Apr 2022]
