molecular function |
| 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:0046972 | | histone acetyltransferase activity (H4-K16 specific) | | Catalysis of the reaction: acetyl-CoA + histone H4 L-lysine (position 16) = CoA + histone H4 N6-acetyl-L-lysine (position 16). This reaction represents the addition of an acetyl group to the lysine at position 16 of histone H4. |
| GO:0004468 | | lysine N-acetyltransferase activity, acting on acetyl phosphate as donor | | Catalysis of the reaction: acetyl phosphate + L-lysine = phosphate + N6-acetyl-L-lysine. |

| 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).

biological process |
| GO:0000077 | | DNA damage checkpoint | | A cell cycle checkpoint that regulates progression through the cell cycle in response to DNA damage. A DNA damage checkpoint may blocks cell cycle progression (in G1, G2 or metaphase) or slow the rate at which S phase proceeds. |
| GO:0030330 | | DNA damage response, signal transduction by p53 class mediator | | A cascade of processes induced by the cell cycle regulator phosphoprotein p53, or an equivalent protein, in response to the detection of DNA damage. |
| 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:0071479 | | cellular response to ionizing radiation | | 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 ionizing radiation stimulus. Ionizing radiation is radiation with sufficient energy to remove electrons from atoms and may arise from spontaneous decay of unstable isotopes, resulting in alpha and beta particles and gamma rays. Ionizing radiation also includes X-rays. |
| GO:0007549 | | dosage compensation | | Compensating for the variation in the unpaired sex chromosome:autosome chromosome ratios between sexes by activation or inactivation of genes on one or both of the sex chromosomes. |
| GO:0009047 | | dosage compensation by hyperactivation of X chromosome | | Compensating for the two-fold variation in X-chromosome:autosome ratios between sexes by a global hyperactivation of all, or most of, the genes on the X-chromosome in the heterogametic sex, leading to a two-fold increase in gene expression from this chromosome. An example of this is found in Drosophila melanogaster. |
| GO:0043984 | | histone H4-K16 acetylation | | The modification of histone H4 by the addition of an acetyl group to a lysine residue at position 16 of the histone. |
| GO:0016573 | | histone acetylation | | The modification of a histone by the addition of an acetyl group. |
| GO:0043066 | | negative regulation of apoptotic process | | Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process. |
| GO:0018394 | | peptidyl-lysine acetylation | | The acetylation of peptidyl-lysine. |
| GO:0051091 | | positive regulation of sequence-specific DNA binding transcription factor activity | | Any process that activates or increases the frequency, rate or extent of activity of a transcription factor, any factor involved in the initiation or regulation of transcription. |
| GO:2000873 | | regulation of histone H4 acetylation involved in response to DNA damage stimulus | | Any process that modulates the frequency, rate or extent of histone H4 acetylation involved in response to DNA damage stimulus. |
| GO:0006355 | | regulation of transcription, DNA-templated | | Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. |
| GO:0010212 | | response to ionizing radiation | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a ionizing radiation stimulus. Ionizing radiation is radiation with sufficient energy to remove electrons from atoms and may arise from spontaneous decay of unstable isotopes, resulting in alpha and beta particles and gamma rays. Ionizing radiation also includes X-rays. |
cellular component |
| GO:0072487 | | MSL complex | | A histone acetyltransferase complex that catalyzes the acetylation of a histone H4 lysine residue at position 16. In human, it contains the catalytic subunit MOF, and MSL1, MSL2 and MSL3. |
| GO:0044545 | | NSL complex | | A histone acetyltransferase complex that catalyzes the acetylation of a histone H4 lysine residues at several positions. In human, it contains the catalytic subunit MOF, NSL1/KIAA1267, NSL2/KANSL2, NSL3/KANSL3, MCRS1, PHF20, OGT1, WDR5 and HCF1. |
| 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:0016456 | | X chromosome located dosage compensation complex, transcription activating | | An RNA-protein complex localized to the X chromosome of males where it is required for the hyper-transcriptional activation of the X chromosome. An example of this is found in Drosophila melanogaster. |

| 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. |
| GO:0005705 | | polytene chromosome interband | | A stretch of less tightly packed chromatin along the polytene chromosome, found between bands. |
| GO:0005667 | | transcription factor complex | | A protein complex that is capable of associating with DNA by direct binding, or via other DNA-binding proteins or complexes, and regulating transcription. |
