Background Information Transcription factor II human (TFIIH) basal transcription factor complex helicase XPB subunit (EC 3.6.4.12; UniProt P19447; also known as BTF2 p89, DNA excision repair protein ERCC-3, DNA repair helicase, DNA repair protein complementing XP-B cells, TFIIH 89 kDa subunit, TFIIH basal transcription factor complex 89 kDa subunit, TFIIH p89, Basic transcription factor 2 89 kDa subunit, Xeroderma pigmentosum group B-complementing protein) is encoded by the ERCC3 (also known as BTF2, GTF2H, RAD25, TFIIH, XPB) gene (Gene ID 2071) in human. DNA lesions caused by UV irradiation, drugs, or other environmental factors are eliminated by two nucleotide excision repair (NER) pathways, Global genome repair (GGR) and transcription-coupled repair (TCR). In GGR, the removal of lesions requires their recognition by the repair factor XPC/HR23b and the subsequent opening of the DNA duplex by TFIIH. The resulting single-stranded structure is stabilized by XPA and replication protein A (RPA). XPG is recruited through its interaction with TFIIH on the 3′ side of the lesion and its positioning on the cut site requires RPA. The interaction between XPA and XPB (ERCC1) stimulates the recruitment of ERCC1-XPF on the 5′ side of the DNA lesion. The damaged oligonucleotide can then be removed through the double incision by XPG and ERCC1-XPF endonucleases. In TCR, these factors (except XPC/HR23B) are recruited by the stalled RNA pol II in front of the damage with the help of the CSB and CSA proteins.

Application Notes Western Blotting Analysis: A representative lot detected Xpb in murine embryonic fibroblasts (MEFs) and HeLa cells, as well as in transgenic animal-derived MEFs expressing Xpb lacking last 43 C-terminal amino acids (Andressoo, J.O., et al. (2009). Mol Cell Biol.29(5):1276-290).
Western Blotting Analysis: A representative lot detected endougenous as well as exogenously expressed Xpb in both U2OS17 whole cell lysate and in THIIF p62 subunit immunoprecipitate (Ziani, S., et al. (2014). J Cell Biol.;206(5):589-598).
Western Blotting Analysis: A representative lot detected Xpb in THIIF TTDA subunit immunoprecipitate (Giglia-Mari,G., et al. (2006). PLoS Biol. 4(6): e156).
Immunocytochemistry Analysis: A representative lot detected XPB recruitment to the DNA damage sites in the nuclei of UV-irradated HeLa cells (Alekseev, S., et al. (2014). Chem Biol. 21(3):398-407).
