molecular function |
| GO:0001106 | | RNA polymerase II transcription corepressor activity | | Interacting selectively and non-covalently with an RNA polymerase II repressing transcription factor and also with the RNA polymerase II basal transcription machinery in order to stop, prevent, or reduce the frequency, rate or extent of transcription. Cofactors generally do not bind DNA, but rather mediate protein-protein interactions between repressive transcription factors and the basal transcription machinery. |
| GO:0003682 | | chromatin binding | | Interacting selectively and non-covalently with chromatin, the network of fibers of DNA, protein, and sometimes RNA, that make up the chromosomes of the eukaryotic nucleus during interphase. |
| GO:0004407 | | histone deacetylase activity | | Catalysis of the reaction: histone N6-acetyl-L-lysine + H2O = histone L-lysine + acetate. This reaction represents the removal of an acetyl group from a histone, a class of proteins complexed to DNA in chromatin and chromosomes. |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| GO:0003714 | | transcription corepressor activity | | Interacting selectively and non-covalently with a repressing transcription factor and also with the basal transcription machinery in order to stop, prevent, or reduce the frequency, rate or extent of transcription. Cofactors generally do not bind the template nucleic acid, but rather mediate protein-protein interactions between repressive transcription factors and the basal transcription machinery. |
biological process |
| GO:0048738 | | cardiac muscle tissue development | | The process whose specific outcome is the progression of cardiac muscle over time, from its formation to the mature structure. |
| GO:0016575 | | histone deacetylation | | The modification of histones by removal of acetyl groups. |
| GO:0045786 | | negative regulation of cell cycle | | Any process that stops, prevents or reduces the rate or extent of progression through the cell cycle. |
| GO:0000122 | | negative regulation of transcription from RNA polymerase II promoter | | Any process that stops, prevents, or reduces the frequency, rate or extent of transcription from an RNA polymerase II promoter. |
| GO:0045892 | | negative regulation of transcription, DNA-templated | | Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription. |
| GO:0006355 | | regulation of transcription, DNA-templated | | Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. |
| GO:0007519 | | skeletal muscle tissue development | | The developmental sequence of events leading to the formation of adult skeletal muscle tissue. The main events are: the fusion of myoblasts to form myotubes that increase in size by further fusion to them of myoblasts, the formation of myofibrils within their cytoplasm and the establishment of functional neuromuscular junctions with motor neurons. At this stage they can be regarded as mature muscle fibers. |
| GO:0006351 | | transcription, DNA-templated | | The cellular synthesis of RNA on a template of DNA. |
cellular component |
| GO:0016580 | | Sin3 complex | | 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. |
| GO:0000805 | | X chromosome | | The sex chromosome present in both sexes of species in which the male is the heterogametic sex. Two copies of the X chromosome are present in each somatic cell of females and one copy is present in males. |
| GO:0001741 | | XY body | | A structure found in a male mammalian spermatocyte containing an unpaired X chromosome that has become densely heterochromatic, silenced and localized at the nuclear periphery. |
| GO:0000806 | | Y chromosome | | The sex chromosome present in males of species in which the male is the heterogametic sex; generally, the sex chromosome that pairs with the X chromosome in the heterogametic sex. The Y chromosome is absent from the cells of females and present in one copy in the somatic cells of males. |
| GO:0030849 | | autosome | | Any chromosome other than a sex chromosome. |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
