Xeroderma pigmentosum, complementation group A

XPA, xeroderma pigmentosum complementation group A
This gene encodes a zinc finger protein involved in DNA excision repair. The encoded protein is part of the NER (nucleotide excision repair) complext which is responsible for repair of UV radiation-induced photoproducts and DNA adducts induced by chemical carcinogens. Mutations in this gene are associated with xeroderma pigmentosum complementation group A. Alternatively spliced transcript variants have been found for this gene.

At least three systems have been used to analyze the effect of nucleosome folding on nucleotide excision repair (NER) in vitro: (a) human cell extracts that have to rely on labeling of repair synthesis to monitor DNA repair, due to very low repair efficacy; (b) Xenopus oocyte nuclear extracts, that have very robust DNA repair efficacy, have been utilized to follow direct removal of DNA damage; (c) six purified human DNA repair factors (RPA, XPA, XPC, TFIIH, XPG, and XPF-ERCC1) that have been used to reconstitute excision repair in vitro.
