      Background InformationDNA repair protein complementing XP-A cells (UniProt P23025; also known as Excision repair-controlling, Mutant xeroderma pigmentosum complementation group A, Xeroderma pigmentosum group A-complementing protein) is encoded by the XPA (also known as XP1, XPAC) gene (Gene ID 7507) 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 transcription factor II human (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.
