Defective nucleotide excision repair in yeast hpr1 and tho2 mutants.
Nucleotide excision repair (NER) and transcription are intimately related. First, TFIIH has a dual role in transcription initiation and NER and, secondly, transcription leads to more efficient repair of damage present in transcribed sequences. It is thought that elongating RNAPII, stalled at a DNA lesion, is used for the loading of the NER machinery in a process termed transcription-coupled rep...
متن کاملRoles of Rad23 protein in yeast nucleotide excision repair.
Nucleotide excision repair (NER) removes many different types of DNA lesions. Most NER proteins are indispensable for repair. In contrast, the yeast Rad23 represents a class of accessory NER proteins, without which NER activity is reduced but not eliminated. In mammals, the complex of HR23B (Rad23 homolog) and XPC (yeast Rad4 homolog) has been suggested to function in the damage recognition ste...
متن کاملNucleotide excision repair. II: From yeast to mammals.
An intricate network of repair systems safeguards the integrity of genetic material, by eliminating DNA lesions induced by numerous environmental and endogenous genotoxic agents. Nucleotide excision repair (NER) is one of the most versatile DNA repair systems. Deficiencies in this process give rise to the classical human DNA repair disorders xeroderma pigmentosum (XP) and Cockayne's syndrome (C...
متن کاملRecovery of RNA polymerase II synthesis following DNA damage in mutants of Saccharomyces cerevisiae defective in nucleotide excision repair.
We have measured the kinetics of the recovery of mRNA synthesis in the inducible GAL10 and RNR3 genes after exposure of yeast cells to ultraviolet (UV) radiation. Such recovery is abolished in mutant strains defective in nucleotide excision repair (NER) of DNA, including a rad23 mutant. Mutants defective in the RAD7 or RAD16 genes, which are required for the repair of the non-transcribed strand...
متن کاملProkaryotic nucleotide excision repair.
Nucleotide excision repair (NER) has allowed bacteria to flourish in many different niches around the globe that inflict harsh environmental damage to their genetic material. NER is remarkable because of its diverse substrate repertoire, which differs greatly in chemical composition and structure. Recent advances in structural biology and single-molecule studies have given great insight into th...
