| molecular function |
|---|
| | GO:0005524 | | ATP binding | | Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| | GO:0003677 | | DNA binding | | Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). |
| | GO:0008094 | | DNA-dependent ATPase activity | | Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction requires the presence of single- or double-stranded DNA, and it drives another reaction. |
| | GO:0003690 | | double-stranded DNA binding | | Interacting selectively and non-covalently with double-stranded DNA. |
| | GO:0004520 | | endodeoxyribonuclease activity | | Catalysis of the hydrolysis of ester linkages within deoxyribonucleic acid by creating internal breaks. |
| | GO:0000400 | | four-way junction DNA binding | | Interacting selectively and non-covalently with DNA containing four-way junctions, also known as Holliday junctions, a structure where two DNA double strands are held together by reciprocal exchange of two of the four strands, one strand each from the two original helices. |
| | GO:0042802 | | identical protein binding | | Interacting selectively and non-covalently with an identical protein or proteins. |
| | GO:0000166 | | nucleotide binding | | Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose. |
| | GO:0000150 | | recombinase activity | | Catalysis of the identification and base-pairing of homologous sequences between single-stranded DNA and double-stranded DNA. |
| | GO:0003697 | | single-stranded DNA binding | | Interacting selectively and non-covalently with single-stranded DNA. |
| biological process |
|---|
| | GO:0006259 | | DNA metabolic process | | Any cellular metabolic process involving deoxyribonucleic acid. This is one of the two main types of nucleic acid, consisting of a long, unbranched macromolecule formed from one, or more commonly, two, strands of linked deoxyribonucleotides. |
| | GO:0000730 | | DNA recombinase assembly | | The aggregation, arrangement and bonding together of strand exchange proteins (recombinases) into higher order oligomers on single-stranded DNA. |
| | GO:0006310 | | DNA recombination | | Any process in which a new genotype is formed by reassortment of genes resulting in gene combinations different from those that were present in the parents. In eukaryotes genetic recombination can occur by chromosome assortment, intrachromosomal recombination, or nonreciprocal interchromosomal recombination. Intrachromosomal recombination occurs by crossing over. In bacteria it may occur by genetic transformation, conjugation, transduction, or F-duction. |
| | 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:0070192 | | chromosome organization involved in meiotic cell cycle | | A process of chromosome organization that is involved in a meiotic cell cycle. |
| | 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:0045002 | | double-strand break repair via single-strand annealing | | Repair of a DSB made between two repeated sequences oriented in the same direction occurs primarily by the single strand annealing pathway. The ends of the break are processed by a 5' to 3' exonuclease, exposing complementary single-strand regions of the direct repeats that can anneal, resulting in a deletion of the unique DNA between the direct repeats. |
| | GO:0030491 | | heteroduplex formation | | The formation of a stable duplex DNA that contains one strand from each of the two recombining DNA molecules. |
| | GO:0000709 | | meiotic joint molecule formation | | The conversion of the paired broken DNA and homologous duplex DNA into a four-stranded branched intermediate, known as a joint molecule, formed during meiotic recombination. These joint molecules contain Holliday junctions on either side of heteroduplex DNA. |
| | GO:1990426 | | mitotic recombination-dependent replication fork processing | | Replication fork processing that includes recombination between DNA near the arrested fork and homologous sequences. Proteins involved in homologous recombination are required for replication restart. |
| | GO:0007131 | | reciprocal meiotic recombination | | The cell cycle process in which double strand breaks are formed and repaired through a double Holliday junction intermediate. This results in the equal exchange of genetic material between non-sister chromatids in a pair of homologous chromosomes. These reciprocal recombinant products ensure the proper segregation of homologous chromosomes during meiosis I and create genetic diversity. |
| | 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. |
| | GO:0042148 | | strand invasion | | The process in which the nucleoprotein complex (composed of the broken single-strand DNA and the recombinase) searches and identifies a region of homology in intact duplex DNA. The broken single-strand DNA displaces the like strand and forms Watson-Crick base pairs with its complement, forming a duplex in which each strand is from one of the two recombining DNA molecules. |
| | GO:0000722 | | telomere maintenance via recombination | | Any recombinational process that contributes to the maintenance of proper telomeric length. |
| cellular component |
|---|
| | GO:0005694 | | chromosome | | A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information. |
| | GO:0000794 | | condensed nuclear chromosome | | A highly compacted molecule of DNA and associated proteins resulting in a cytologically distinct nuclear chromosome. |
| | GO:0000228 | | nuclear chromosome | | A chromosome that encodes the nuclear genome and is found in the nucleus of a eukaryotic cell during the cell cycle phases when the nucleus is intact. |
| | GO:0005654 | | nucleoplasm | | That part of the nuclear content other than the chromosomes or the nucleolus. |
| | 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. |
