Induced mutagenic effects in the nucleotide excision repair deficient Drosophila mutant mus201D1, expressing a truncated XPG protein

, : Induced mutagenic effects in the nucleotide excision repair deficient Drosophila mutant mus201D1, expressing a truncated XPG protein. Mutation Research 461(4): 279-288, 5 January

Defects in nucleotide excision repair (NER) as defined by the UV sensitivity of xeroderma pigmentosurn (XP), Cockayne syndrome (CS) and trichothiodystrophy (TTD) patients has lead to the identification of most of the genes involved: XPA through XPG, CSA and CSB. Whereas XP patients often show an increased risk for skin cancer after exposure to sunlight, this is not the case for patients with CS and TTD. Several CS patients have been shown to carry a defect in the XPG gene. The XPG, a structure specific endonuclease makes the incision 3' of damage and is also involved in the subsequent 5'incision during the NER process. In addition, XPG plays a role in the removal of oxidative DNA damage. The Drosophila XPG gene was isolated and based on the molecular defect of a spontaneous (insertion) and an EMS induced mutant, it was shown that a mutated XPG is responsible for the Drosophila mutagen-sensitive mutants mus201. One of these mutants, mus201D1 has been used extensively in studies of the effects and mechanisms of many chemical mutagens as well as X-rays. The results of these studies are discussed in the light of the finding that mus201p is the Drosophila homologue of XPG.
