Structural basis for the recruitment of ERCC1-XPF to nucleotide excision repair complexes by XPA.
The nucleotide excision repair (NER) pathway corrects DNA damage caused by sunlight, environmental mutagens and certain antitumor agents. This multistep DNA repair reaction operates by the sequential assembly of protein factors at sites of DNA damage. The efficient recognition of DNA damage and its repair are orchestrated by specific protein-protein and protein-DNA interactions within NER compl...
متن کاملStructural features of the minimal DNA binding domain (M98-F219) of human nucleotide excision repair protein XPA.
XPA, an essential protein in nucleotide excision repair (NER), interacts with damaged DNA and other proteins (RPA, ERCC1 and TFIIH) to remove a wide variety of chemically and structurally distinct DNA lesions from the eukaryotic genome. To understand the structural basis for the role of XPA in the repair process, the structure of the minimal DNA binding domain of human XPA [XPA-MBD (M98-F219)] ...
متن کاملCalcium-Binding Capacity of Centrin2 Is Required for Linear POC5 Assembly but Not for Nucleotide Excision Repair
Centrosomes, the principal microtubule-organising centres in animal cells, contain centrins, small, conserved calcium-binding proteins unique to eukaryotes. Centrin2 binds to xeroderma pigmentosum group C protein (XPC), stabilising it, and its presence slightly increases nucleotide excision repair (NER) activity in vitro. In previous work, we deleted all three centrin isoforms present in chicke...
متن کاملReplication factor C recruits DNA polymerase delta to sites of nucleotide excision repair but is not required for PCNA recruitment.
Nucleotide excision repair (NER) operates through coordinated assembly of repair factors into pre- and postincision complexes. The postincision step of NER includes gap-filling DNA synthesis and ligation. However, the exact composition of this NER-associated DNA synthesis complex in vivo and the dynamic interactions of the factors involved are not well understood. Using immunofluorescence, chro...
متن کاملDisruption of DNA repair in cancer cells by ubiquitination of a destabilising dimerization domain of nucleotide excision repair protein ERCC1
DNA repair pathways present in all cells serve to preserve genome stability, but in cancer cells they also act reduce the efficacy of chemotherapy. The endonuclease ERCC1-XPF has an important role in the repair of DNA damage caused by a variety of chemotherapeutic agents and there has been intense interest in the use of ERCC1 as a predictive marker of therapeutic response in non-small cell lung...
