Фон
General transcription and DNA repair factor IIH helicase/translocase subunit XPB is a ~89 kDa protein. 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 localized melting that allows XPD/ERCC2 helicase to anchor.
