Abstract

In yeast, global genome nucleotide-excision repair (GG-NER) requires a protein complex containing Rad7 and Rad16. Rad16 is a member of the switch/sucrose nonfermentable superfamily, and it is presumed that chromatin remodelling is its primary function during repair. We show that RAD16 is required for ultraviolet-dependent hyperacetylation of histone H3 (Lys 9 and Lys 14) at the MFA2 promoter and throughout the genome. The yeast repressor complex Ssn6-Tup1 represses many genes including MFA2. TUP1 deletion results in constitutive hyperacetylation of histone H3, nucleosome disruption and derepression of gene transcription in Tup1-regulated genes. GG-NER in the MFA2 promoter proceeds more rapidly in tup1Delta alpha-cells compared with wild type, even when transcription is inhibited. We show that elevated histone H3 acetylation levels in the MFA2 promoter in tup1Delta alpha-cells result in Rad7- and Rad16-independent GG-NER, and that Rad16 mediates the ultraviolet-induced acetylation of histone H3, necessary for efficient GG-NER.
