| | GO:0004402 | | histone acetyltransferase activity | | Catalysis of the reaction: acetyl-CoA + histone = CoA + acetyl-histone. |
| | GO:0035064 | | methylated histone binding | | Interacting selectively and non-covalently with a histone in which a residue has been modified by methylation. Histones are any of a group of water-soluble proteins found in association with the DNA of eukaroytic 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). |
| 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: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:0051276 | | chromosome organization | | A process that is carried out at the cellular level that results in the assembly, arrangement of constituent parts, or disassembly of chromosomes, structures composed of a very long molecule of DNA and associated proteins that carries hereditary information. This term covers covalent modifications at the molecular level as well as spatial relationships among the major components of a chromosome. |
| | GO:0051304 | | chromosome separation | | The cell cycle process in which paired chromosomes are detached from each other. Chromosome separation begins with the release of cohesin complexes from chromosomes; in budding yeast, this includes the cleavage of cohesin complexes along the chromosome arms, followed by the separation of the centromeric regions. Chromosome separation also includes formation of chromatid axes mediated by condensins, and ends with the disentangling of inter-sister catenation catalyzed by topoisomerase II (topo II). |
| | 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:0043486 | | histone exchange | | The replacement, within chromatin, of resident histones or histone subunits with alternative, sometimes variant, histones or subunits. |
| | GO:0006355 | | regulation of transcription, DNA-templated | | Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. |
| | 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: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. |
