| molecular function |
|---|
| | GO:0004003 | | ATP-dependent DNA helicase activity | | Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction drives the unwinding of the DNA helix. |
| | GO:0003684 | | damaged DNA binding | | Interacting selectively and non-covalently with damaged DNA. |
| | 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:0032508 | | DNA duplex unwinding | | The process in which interchain hydrogen bonds between two strands of DNA are broken or 'melted', generating a region of unpaired single strands. |
| | 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:0006302 | | double-strand break repair | | The repair of double-strand breaks in DNA via homologous and nonhomologous mechanisms to reform a continuous DNA helix. |
| | GO:0000724 | | double-strand break repair via homologous recombination | | The error-free repair of a double-strand break in DNA in which the broken DNA molecule is repaired using homologous sequences. A strand in the broken DNA searches for a homologous region in an intact chromosome to serve as the template for DNA synthesis. The restoration of two intact DNA molecules results in the exchange, reciprocal or nonreciprocal, of genetic material between the intact DNA molecule and the broken DNA molecule. |
| | 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:0042138 | | meiotic DNA double-strand break formation | | The cell cycle process in which double-strand breaks are generated at defined hotspots throughout the genome during meiosis I. This results in the initiation of meiotic recombination. |
| | GO:0044773 | | mitotic DNA damage checkpoint | | A mitotic cell cycle checkpoint that detects and negatively regulates progression through the cell cycle in response to DNA damage. |
| | GO:0007095 | | mitotic G2 DNA damage checkpoint | | A mitotic cell cycle checkpoint that detects and negatively regulates progression through the G2/M transition of the cell cycle in response to DNA damage. |
| | GO:0033127 | | regulation of histone phosphorylation | | Any process that modulates the frequency, rate or extent of the addition of one or more phosphate groups to a histone protein. |
| | GO:0042770 | | signal transduction in response to DNA damage | | A cascade of processes induced by the detection of DNA damage within a cell. |
| | GO:0016233 | | telomere capping | | A process in which telomeres are protected from degradation and fusion, thereby ensuring chromosome stability by protecting the ends from both degradation and from being recognized as damaged DNA. May be mediated by specific single- or double-stranded telomeric DNA binding proteins. |
| | GO:0000723 | | telomere maintenance | | Any process that contributes to the maintenance of proper telomeric length and structure by affecting and monitoring the activity of telomeric proteins, the length of telomeric DNA and the replication and repair of the DNA. These processes includes those that shorten, lengthen, replicate and repair the telomeric DNA sequences. |
| cellular component |
|---|
| | GO:0030870 | | Mre11 complex | | Trimeric protein complex that possesses endonuclease activity; involved in meiotic recombination, DNA repair and checkpoint signaling. In Saccharomyces cerevisiae, the complex comprises Mre11p, Rad50p, and Xrs2p; complexes identified in other species generally contain proteins orthologous to the Saccharomyces cerevisiae proteins. |
| | GO:0005694 | | chromosome | | A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information. |
| | GO:0000781 | | chromosome, telomeric region | | The terminal region of a linear chromosome that includes the telomeric DNA repeats and associated proteins. |
| | GO:0000784 | | nuclear chromosome, telomeric region | | The terminal region of a linear nuclear 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. |
