The 9-1-1 complex is recruited to DNA lesion upon damage by the RAD17-replication factor C (RFC) clamp loader complex. Acts then as a sliding clamp platform on DNA for several proteins involved in long-patch base excision repair (LP-BER). The 9-1-1 complex stimulates DNA polymerase beta (POLB) activity by increasing its affinity for the 3'-OH end of the primer-template and stabilizes POLB to those sites where LP-BER proceeds; endonuclease FEN1 cleavage activity on substrates with double, nick, or gap flaps of distinct sequences and lengths; and DNA ligase I (LIG1) on long-patch base excision repair substrates. The 9-1-1 complex is necessary for the recruitment of RHNO1 to sites of double-stranded breaks (DSB) occurring during the S phase. {ECO:0000269|PubMed:21659603}. |Hus1| |meiotic DNA integrity checkpoint| |checkpoint clamp complex| |meiotic cell cycle checkpoint| |mitotic DNA replication checkpoint| |intra-S DNA damage checkpoint| |DNA replication checkpoint| |mitotic G2/M transition checkpoint| |negative regulation of DNA replication| |site of double-strand break| |cellular response to ionizing radiation| |negative regulation of G2/M transition of mitotic cell cycle| |mitotic DNA damage checkpoint| |double-strand break repair via homologous recombination| |telomere maintenance| |recombinational repair| |negative regulation of cell cycle G2/M phase transition| |telomere organization| |mitotic DNA integrity checkpoint| |regulation of DNA replication| |nucleotide-excision repair| |DNA damage checkpoint| |response to UV| |DNA integrity checkpoint| |response to ionizing radiation| |mitotic cell cycle checkpoint| |meiotic cell cycle process| |cellular response to radiation| |double-strand break repair| |regulation of signal transduction by p53 class mediator| |cell cycle checkpoint| |regulation of G2/M transition of mitotic cell cycle| |regulation of cell cycle G2/M phase transition| |negative regulation of mitotic cell cycle phase transition| |DNA replication| |DNA recombination| |meiotic cell cycle| |negative regulation of cell cycle phase transition| |response to light stimulus| |negative regulation of mitotic cell cycle| |cellular response to environmental stimulus| |cellular response to abiotic stimulus| |negative regulation of cell cycle process| |anatomical structure homeostasis| |regulation of mitotic cell cycle phase transition| |response to radiation| |regulation of cell cycle phase transition| |DNA repair| |negative regulation of cell cycle| |mitotic cell cycle process| |regulation of mitotic cell cycle| |embryo development ending in birth or egg hatching| |mitotic cell cycle| |DNA metabolic process| |regulation of cell cycle process| |cellular response to DNA damage stimulus| |nucleolus| |protein phosphorylation| |embryo development| |cell cycle process| |chromosome organization| |response to abiotic stimulus| |regulation of cell cycle| |phosphorylation| |cell cycle| |negative regulation of cellular macromolecule biosynthetic process| |reproductive process| |reproduction| |regulation of protein phosphorylation| |negative regulation of macromolecule biosynthetic process| |negative regulation of cellular biosynthetic process| |negative regulation of biosynthetic process| |regulation of phosphorylation| |homeostatic process| |cellular response to stress| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| |regulation of phosphate metabolic process| |regulation of phosphorus metabolic process| |regulation of intracellular signal transduction| |regulation of protein modification process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp391|Pomalidomide 20μM R07 exp391]]|-1.96| |[[:results:exp334|All-trans-Retinoic-Acid 40μM R07 exp334]]|-1.95| |[[:results:exp78|Pterostilbene 16μM R02 exp78]]|-1.9| |[[:results:exp512|Olaparib 4μM R08 exp512]]|-1.89| |[[:results:exp354|Diepoxybutane 3μM R07 exp354]]|-1.87| |[[:results:exp345|Cidofovir 10μM R07 exp345]]|-1.86| |[[:results:exp282|Fluvastatin 2.2μM R06 exp282]]|-1.79| |[[:results:exp335|Aminopterin 0.005μM R07 exp335]]|-1.73| |[[:results:exp329|Hydroxyurea 100μM R07 exp329]]|-1.72| |[[:results:exp431|Rotenone 0.07μM R08 exp431]]|-1.7| No correlation found to any other genes in chemogenomics.
