The ATP-dependent chromatin remodeling enzyme Fun30 represses transcription by sliding promoter proximal nucleosomes [array]

ABSTRACT: The evolutionarily conserved ATP-dependent chromatin remodeling enzyme Fun30 has recently been shown to play important roles in heterochromatin silencing and DNA repair. However, how Fun30 remodels nucleosomes is not clear. Here we report a nucleosome sliding activity of Fun30 and its role in transcriptional repression. We observed that Fun30 repressed the expression of genes involved in amino acid and carbohydrate metabolism, the stress response, and meiosis. In addition, Fun30 was localized at the 5′ and 3′ ends of genes and within the open reading frames of its targets. Consistent with its role in gene repression, we observed that Fun30-target genes lacked histone modifications often associated with gene activation and showed an increased level of ubiquitinated histone H2B.
