SUMMARY PARAGRAPH for HOS3

HOS3 encodes a histone deacetylase (1). Covalent modifications of histones, including acetylation and deacetylation, are implicated in transcriptional regulation in yeast and other eukaryotes, and have been reviewed in 4 and 5. Four other histone deactylases, Rpd3p, Hda1p, Hos1p, and Hos2p, have been identified in yeast; all share sequence similarity (1). Different yeast histone deacetylase complexes affect transcription of distinct, partially overlapping sets of genes (1, 5).
