摘要: Histone deacetylases, typified by class I Rpd3 in the yeast Saccharomyces cerevisiae, have historically been associated with gene repression. We now demonstrate that Hos2, another member of family, binds to coding regions genes primarily during activation, when it specifically deacetylates lysines H3 and H4 histone tails. Moreover, Hos2 is preferentially high activity genome-wide. also show an factor, Set3, are necessary for efficient transcription. Therefore, our data indicate that, contrast other directly required activation.
