| molecular function |
|---|
| | GO:0010485 | | H4 histone acetyltransferase activity | | Catalysis of the reaction: acetyl-CoA + histone H4 = CoA + acetyl-histone H4. |
| | GO:0008080 | | N-acetyltransferase activity | | Catalysis of the transfer of an acetyl group to a nitrogen atom on the acceptor molecule. |
| | 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:0004402 | | histone acetyltransferase activity | | Catalysis of the reaction: acetyl-CoA + histone = CoA + acetyl-histone. |
| | GO:0042393 | | histone binding | | Interacting selectively and non-covalently with a histone, any of a group of water-soluble proteins found in association with the DNA of eukaroytic chromosomes. They are involved in the condensation and coiling of chromosomes during cell division and have also been implicated in nonspecific suppression of gene activity. |
| | 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:0016740 | | transferase activity | | Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2. |
| | GO:0016746 | | transferase activity, transferring acyl groups | | Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor). |
| 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:0006348 | | chromatin silencing at telomere | | Repression of transcription of telomeric DNA by altering the structure of chromatin. |
| | 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. |
| cellular component |
|---|
| | GO:0000781 | | chromosome, telomeric region | | The terminal region of a linear chromosome that includes the telomeric DNA repeats and associated proteins. |
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0000123 | | histone acetyltransferase complex | | A protein complex that possesses histone acetyltransferase activity. |
| | GO:0000790 | | nuclear chromatin | | The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome in the nucleus. |
| | 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. |
