EOG8NW20H GO:0000077 25/87 DNA damage checkpoint biological_process "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." [GOC:mtg_cell_cycle] EOG8NW20H GO:0006281 25/87 DNA repair biological_process "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." [PMID:11563486] EOG8NW20H GO:0030896 25/87 checkpoint clamp complex cellular_component "Conserved heterotrimeric complex of PCNA-like proteins that is loaded onto DNA at sites of DNA damage." [PMID:12531008] EOG8NW20H GO:0008853 2/87 exodeoxyribonuclease III activity molecular_function "Catalysis of the degradation of double-stranded DNA. It acts progressively in a 3' to 5' direction, releasing 5'-phosphomononucleotides." [EC:3.1.11.2] EOG8NW20H GO:0005515 1/87 protein binding molecular_function "Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules)." [GOC:go_curators] EOG8NW20H GO:0005634 1/87 nucleus cellular_component "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." [GOC:go_curators] EOG8NW20H GO:0031965 1/87 nuclear membrane cellular_component "Either of the lipid bilayers that surround the nucleus and form the nuclear envelope; excludes the intermembrane space."
