Repair of plasmid and genomic DNA in arad7Δ mutant of yeast [PDF]
Nucleic Acids Research, 1995 Repair of UV-induced cyclobutane pyrimidine dimers (CPDs) was examined in a yeast plasmid of known chromatin structure and in genomic DNA in a radiation-sensitive deletion mutant of yeast, rad7 delta, and its isogenic wild-type strain. A whole plasmid repair assay revealed that only approximately 50% of the CPDs in plasmid DNA are repaired after 6 h in

Photoreactivation Activities of Rad5, Rad16A and Rad16B Help Beauveria bassiana to Recover from Solar Ultraviolet Damage [PDF]
Journal of FungiIn budding yeast, Rad5 and Rad7-Rad16 play respective roles in the error-free post-replication repair and nucleotide excision repair of ultraviolet-induced DNA damage; however, their homologs have not yet been studied in non-yeast fungi.

Regulated expression of theSaccharomyces cerevisiaeDNA repair gene RAD7 in response to DNA damage and during sporulation [PDF]
Nucleic Acids Research, 1990 The RAD7 gene of Saccharomyces cerevisiae affects the proficiency of excision repair of DNA damaged by UV light. Here, we report our studies on the regulation of the RAD7 gene in response to UV irradiation and during sporulation. RAD7 transcript levels increased 6-fold within 40 min of exposure of cells to 37 J/m2 of UV light.

RAD7 Gene of Saccharomyces cerevisiae: Transcripts, Nucleotide Sequence Analysis, and Functional Relationship between the RAD7 and RAD23 Gene Products [PDF]
Molecular and Cellular Biology, 1986 The RAD7 gene of Saccharomyces cerevisiae was cloned on a 4.0-kilobase (kb) DNA fragment and shown to provide full complementation of a rad7-delta mutant strain. The nucleotide sequence of a 2.2-kb DNA fragment which contains the complete RAD7 gene was determined. Transcription of the RAD7 gene initiates at multiple sites in a region spanning positions

Advances in biological chemistry, 2015 During Nucleotide Excision Repair (NER) in the yeast S. cerevisiae, ubiquitylation of Rad4 is carried out by the E3 ubiquitin ligase that includes Rad7-Elc1-Cul3 and is critical to optimal NER. Rad7 E3 activity targets Rad4 for degradation by the proteaseome but, in principle, could also trigger other DNA damage responses. We observed increased nuclear
