| biological process |
|---|
| | GO:0000729 | | DNA double-strand break processing | | The 5' to 3' exonucleolytic resection of the DNA at the site of the break to form a 3' single-strand DNA overhang. |
| | 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:0006260 | | DNA replication | | The cellular metabolic process in which a cell duplicates one or more molecules of DNA. DNA replication begins when specific sequences, known as origins of replication, are recognized and bound by initiation proteins, and ends when the original DNA molecule has been completely duplicated and the copies topologically separated. The unit of replication usually corresponds to the genome of the cell, an organelle, or a virus. The template for replication can either be an existing DNA molecule or RNA. |
| | GO:0000731 | | DNA synthesis involved in DNA repair | | Synthesis of DNA that proceeds from the broken 3' single-strand DNA end and uses the homologous intact duplex as the template. |
| | GO:0007050 | | cell cycle arrest | | A regulatory process that halts progression through the cell cycle during one of the normal phases (G1, S, G2, M). |
| | 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:0006303 | | double-strand break repair via nonhomologous end joining | | The repair of a double-strand break in DNA in which the two broken ends are rejoined with little or no sequence complementarity. Information at the DNA ends may be lost due to the modification of broken DNA ends. This term covers instances of separate pathways, called classical (or canonical) and alternative nonhomologous end joining (C-NHEJ and A-NHEJ). These in turn may further branch into sub-pathways, but evidence is still unclear. |
| | 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:0031441 | | negative regulation of mRNA 3'-end processing | | Any process that stops, prevents, or reduces the frequency, rate or extent of mRNA 3'-end processing. |
| | GO:0046826 | | negative regulation of protein export from nucleus | | Any process that stops, prevents, or reduces the frequency, rate or extent of the directed movement of proteins from the nucleus into the cytoplasm. |
| | GO:0043065 | | positive regulation of apoptotic process | | Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process. |
| | GO:0045732 | | positive regulation of protein catabolic process | | Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the breakdown of a protein by the destruction of the native, active configuration, with or without the hydrolysis of peptide bonds. |
| | GO:0085020 | | protein K6-linked ubiquitination | | A protein ubiquitination process in which a polymer of ubiquitin, formed by linkages between lysine residues at position 6 of the ubiquitin monomers, is added to a protein. K6-linked ubiquitination is involved in DNA repair. |
| | GO:0016567 | | protein ubiquitination | | The process in which one or more ubiquitin groups are added to a protein. |
| | GO:0042325 | | regulation of phosphorylation | | Any process that modulates the frequency, rate or extent of addition of phosphate groups into a molecule. |
| | GO:1901796 | | regulation of signal transduction by p53 class mediator | | Any process that modulates the frequency, rate or extent of signal transduction by p53 class mediator. |
| | GO:0000732 | | strand displacement | | The rejection of the broken 3' single-strand DNA molecule that formed heteroduplex DNA with its complement in an intact duplex DNA. The Watson-Crick base pairing in the original duplex is restored. The rejected 3' single-strand DNA molecule reanneals with its original complement to reform two intact duplex molecules. |
| | GO:0001894 | | tissue homeostasis | | A homeostatic process involved in the maintenance of an internal steady state within a defined tissue of an organism, including control of cellular proliferation and death and control of metabolic function. |
| cellular component |

| | GO:0070531 | | BRCA1-A complex | | A protein complex that contains the BRCA1-BARD1 heterodimer, RAP80/UIMC1, BRCC3/BRCC36, BRE/BRCC45, FAM175A/CCDC98/Abraxas and MERIT40/NBA1, and specifically recognizes and binds K63-linked polyubiquitin chains present on histone H2A and H2AX at DNA damage sites. |
| | GO:0031436 | | BRCA1-BARD1 complex | | A heterodimeric complex comprising BRCA1 and BARD1, which possesses ubiquitin ligase activity and is involved in genome maintenance, possibly by functioning in surveillance for DNA damage. |
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0043231 | | intracellular membrane-bounded organelle | | Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. |
| | 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. |
| | GO:0000151 | | ubiquitin ligase complex | | A protein complex that includes a ubiquitin-protein ligase and enables ubiquitin protein ligase activity. The complex also contains other proteins that may confer substrate specificity on the complex. |
