| molecular function |
|---|
| | GO:0003677 | | DNA binding | | Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). |
| | GO:0031151 | | histone methyltransferase activity (H3-K79 specific) | | Catalysis of the reaction: S-adenosyl-L-methionine + histone H3 L-lysine (position 79) = S-adenosyl-L-homocysteine + histone H3 N6-methyl-L-lysine (position 79). This reaction is the addition of a methyl group onto lysine at position 79 of the histone H3 protein. |
| | GO:0018024 | | histone-lysine N-methyltransferase activity | | Catalysis of the reaction: S-adenosyl-L-methionine + histone L-lysine = S-adenosyl-L-homocysteine + histone N6-methyl-L-lysine. The methylation of peptidyl-lysine in histones forms N6-methyl-L-lysine, N6,N6-dimethyl-L-lysine and N6,N6,N6-trimethyl-L-lysine derivatives. |
| | GO:0008168 | | methyltransferase activity | | Catalysis of the transfer of a methyl group to an acceptor molecule. |
| | GO:0031493 | | nucleosomal histone binding | | Interacting selectively and non-covalently with a histone that is assembled into a nucleosome. |
| | 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. |
| 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: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:0044783 | | G1 DNA damage checkpoint | | A cell cycle checkpoint that detects and negatively regulates progression from G1 to S phase in the cell cycle in response to DNA damage. |
| | GO:0006348 | | chromatin silencing at telomere | | Repression of transcription of telomeric DNA by altering the structure of chromatin. |
| | GO:0070911 | | global genome nucleotide-excision repair | | The nucleotide-excision repair process in which DNA lesions are removed from nontranscribed strands and from transcriptionally silent regions over the entire genome. |
| | GO:0034729 | | histone H3-K79 methylation | | The modification of histone H3 by addition of a methyl group to lysine at position 79 of the histone. |
| | GO:0031573 | | intra-S DNA damage checkpoint | | A mitotic cell cycle checkpoint that slows DNA synthesis in response to DNA damage by the prevention of new origin firing and the stabilization of slow replication fork progression. |
| | GO:0051598 | | meiotic recombination checkpoint | | A checkpoint that acts during late prophase I (pachytene) and prevents segregation of homologous chromosomes until recombination is completed, ensuring proper distribution of the genetic material to the gametes. |
| | GO:0032259 | | methylation | | The process in which a methyl group is covalently attached to a molecule. |
| | GO:0006289 | | nucleotide-excision repair | | A DNA repair process in which a small region of the strand surrounding the damage is removed from the DNA helix as an oligonucleotide. The small gap left in the DNA helix is filled in by the sequential action of DNA polymerase and DNA ligase. Nucleotide excision repair recognizes a wide range of substrates, including damage caused by UV irradiation (pyrimidine dimers and 6-4 photoproducts) and chemicals (intrastrand cross-links and bulky adducts). |
| | GO:0006301 | | postreplication repair | | The conversion of DNA-damage induced single-stranded gaps into large molecular weight DNA after replication. Includes pathways that remove replication-blocking lesions in conjunction with DNA replication. |
| | GO:0000725 | | recombinational repair | | A DNA repair process that involves the exchange, reciprocal or nonreciprocal, of genetic material between the broken DNA molecule and a homologous region of DNA. |
| | GO:0051726 | | regulation of cell cycle | | Any process that modulates the rate or extent of progression through the cell cycle. |
| | 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:0000781 | | chromosome, telomeric region | | The terminal region of a linear chromosome that includes the telomeric DNA repeats and associated proteins. |
| | 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. |
