Nucleotide excision repair (NER) of DNA in the yeast Saccharomyces cerevisiae and in human cells has been shown to be a biochemically complex process involving multiple gene products. In yeast, the involvement of the DNA replication accessory proteins, replication protein A (RPA1) and proliferating cell nuclear antigen (PCNA) in NER has not been demonstrated genetically. In this study we have generated temperature-degradable rfa1 and pcna mutants and show that these mutants are defective in NER in vitro under conditions that promote degradation of the RFA1 and PCNA gene products. We also demonstrate a physical interaction between RPA1 protein and subunits of the RNA polymerase II basal transcription factor IIH (TFIIH). Copyright (C) 1998 Elsevier Science B.V.
