| | 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). |
| biological process |

| | GO:0006281 | | DNA repair | | The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway. |
| | GO:0006974 | | cellular response to DNA damage stimulus | | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to its DNA from environmental insults or errors during metabolism. |
| | GO:0006338 | | chromatin remodeling | | Dynamic structural changes to eukaryotic chromatin occurring throughout the cell division cycle. These changes range from the local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation. |
| | GO:0006342 | | chromatin silencing | | Repression of transcription by altering the structure of chromatin, e.g. by conversion of large regions of DNA into an inaccessible state often called heterochromatin. |
| | GO:0043968 | | histone H2A acetylation | | The modification of histone H2A by the addition of an acetyl group. |
| | GO:0043967 | | histone H4 acetylation | | The modification of histone H4 by the addition of an acetyl group. |
| | GO:0016573 | | histone acetylation | | The modification of a histone by the addition of an acetyl group. |
| | GO:0016575 | | histone deacetylation | | The modification of histones by removal of acetyl groups. |
| | GO:0060195 | | negative regulation of antisense RNA transcription | | Any process that decreases the frequency, rate or extent of the synthesis of antisense RNA, an RNA molecule complementary in sequence to another RNA or DNA molecule, which, by binding the latter, acts to inhibit its function and/or completion of synthesis, on a template of DNA. |
| | 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:0030174 | | regulation of DNA-dependent DNA replication initiation | | Any process that modulates the frequency, rate or extent of initiation of DNA-dependent DNA replication; the process in which DNA becomes competent to replicate. In eukaryotes, replication competence is established in early G1 and lost during the ensuing S phase. |
| | GO:0006357 | | regulation of transcription from RNA polymerase II promoter | | Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter. |
| | GO:0006355 | | regulation of transcription, DNA-templated | | Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. |
| | GO:0006368 | | transcription elongation from RNA polymerase II promoter | | The extension of an RNA molecule after transcription initiation and promoter clearance at an RNA polymerase II promoter by the addition of ribonucleotides catalyzed by RNA polymerase II. |
| | GO:0006351 | | transcription, DNA-templated | | The cellular synthesis of RNA on a template of DNA. |
| cellular component |
|---|
| | GO:0035267 | | NuA4 histone acetyltransferase complex | | A complex having histone acetylase activity on chromatin, as well as ATPase, DNA helicase and structural DNA binding activities. The complex is thought to be involved in double-strand DNA break repair. Subunits of the human complex include HTATIP/TIP60, TRRAP, RUVBL1, BUVBL2, beta-actin and BAF53/ACTL6A. In yeast, the complex has 13 subunits, including the catalytic subunit Esa1 (homologous to human Tip60). |
| | GO:0032221 | | Rpd3S complex | | 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). |
| | GO:0000123 | | histone acetyltransferase complex | | A protein complex that possesses histone acetyltransferase activity. |
| | 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. |
