A eukaryotically conserved histone deacetylase complex which deacetylates histones preferentially in promoter regions. Composed of a catalytic histone deacetylase subunit, a chromodomain protein, a SIN3 family co-repressor, and a WD repeat protein (Clr6p, Alp13p, Pst2p, and Prw1p respectively in Schizosaccharomyces; Rpd3p, Sin3p, Ume1p, Rco1p and Eaf3 in Saccharomyces; homologs thereof in other species). The ordered and organized complex of DNA and protein that forms the chromosome in the nucleus. A protein complex that possesses histone deacetylase activity. Any constituent part of a nuclear chromosome, a chromosome found in the nucleus of a eukaryotic cell. A multiprotein complex that functions broadly in eukaryotic organisms as a transcriptional repressor of protein-coding genes, through the gene-specific deacetylation of histones. Amongst its subunits, the Sin3 complex contains Sin3-like proteins, and a number of core proteins that are shared with the NuRD complex (including histone deacetylases and histone binding proteins). The Sin3 complex does not directly bind DNA itself, but is targeted to specific genes through protein-protein interactions with DNA-binding proteins. A histone deacetylase complex which deacetylates histones across gene coding regions. Composed of a catalytic histone deacetylase subunit, an Sds-3 family protein, a SIN3 family co-repressor, a WD repeat protein, and a zf- PHD finger (Clr6, Sds3, Pst1, Prw1, Png2 in Schizosaccharomyces pombe; Rpd3p, Sin3p, Ume1p, Pho23p, Sap30p, Sds3p, Cti6p, Rxt2p, Rxt3p, Dep1p, Ume6p and Ash1p in Saccharomyces cerevisiae). Any complex that mediates dynamic changes in eukaryotic chromatin. Any constituent part of the nucleoplasm, that part of the nuclear content other than the chromosomes or the nucleolus. Any of a number of evolutionarily conserved histone deacetylase complexes (HDACs) containing a core consisting of a paired amphipathic helix motif protein (e.g. Sin3p in S. cerevisiae, Pst1 in S. pombe or Sin3A in mammals) at least one class I histone deacetylase (e.g. Rpd3p in S. cerevisiae, Clr6 in S. pombe, or HDAC1 and HDAC2 in mammals), and at least one WD40 repeat protein (e.g. Ume1p in S. cerevisiae, Prw1 in S. pombe, or RbAp46 and RbAp48 in mammals). These complexes also contain a variable number of other proteins that direct histone binding, DNA binding, or add other functionality to the complex. The ordered and organized complex of DNA and protein that forms the chromosome.
