ERCC3 (General transcription and DNA repair factor IIH helicase/translocase subunit XPB) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as a drug target, a tumour suppressor, a biomarker and a DNA repair gene, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Cervical cancer, Skin cancer, Ovarian cancer and 3 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
ATP-dependent 3'-5' DNA helicase/translocase. Binds dsDNA rather than ssDNA, unzipping it in a translocase rather than classical helicase activity. Component of the general transcription and DNA repair factor IIH (TFIIH) core complex. When complexed to CDK-activating kinase (CAK), involved in RNA transcription by RNA polymerase II. The ATPase activity of XPB/ERCC3, but not its helicase activity, is required for DNA opening; it may wrap around the damaged DNA wedging it open, causing localised melting that allows XPD/ERCC2 helicase to anchor. In transcription, TFIIH has an essential role in transcription initiation. Location: Nucleus (UniProt). Locus 2q14.3 (HGNC).
