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. RAD9A possesses 3'->5' double stranded DNA exonuclease activity. Its phosphorylation by PRKCD may be required for the formation of the 9-1-1 complex. {ECO:0000269|PubMed:10713044, ECO:0000269|PubMed:21659603}. |Rad9| |exodeoxyribonuclease III activity| |checkpoint clamp complex| |positive regulation of intrinsic apoptotic signaling pathway in response to DNA damage| |intra-S DNA damage checkpoint| |DNA replication checkpoint| |3-5 exonuclease activity| |regulation of intrinsic apoptotic signaling pathway in response to DNA damage| |positive regulation of intrinsic apoptotic signaling pathway| |cellular response to ionizing radiation| |mitotic DNA damage checkpoint| |positive regulation of response to DNA damage stimulus| |mitotic DNA integrity checkpoint| |histone deacetylase binding| |SH3 domain binding| |DNA damage checkpoint| |DNA integrity checkpoint| |response to ionizing radiation| |mitotic cell cycle checkpoint| |regulation of intrinsic apoptotic signaling pathway| |positive regulation of apoptotic signaling pathway| |cellular response to radiation| |regulation of signal transduction by p53 class mediator| |cell cycle checkpoint| |DNA replication| |regulation of response to DNA damage stimulus| |nucleic acid phosphodiester bond hydrolysis| |negative regulation of mitotic cell cycle| |cellular response to environmental stimulus| |cellular response to abiotic stimulus| |enzyme binding| |regulation of apoptotic signaling pathway| |response to radiation| |protein kinase binding| |DNA repair| |negative regulation of cell cycle| |mitotic cell cycle process| |regulation of mitotic cell cycle| |positive regulation of apoptotic process| |positive regulation of programmed cell death| |mitotic cell cycle| |positive regulation of cell death| |regulation of cellular response to stress| |DNA metabolic process| |cellular response to DNA damage stimulus| |cell cycle process| |positive regulation of intracellular signal transduction| |response to abiotic stimulus| |regulation of cell cycle| |cell cycle| |regulation of response to stress| |regulation of apoptotic process| |regulation of programmed cell death| |positive regulation of signal transduction| |regulation of cell death| |cellular response to stress| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| |positive regulation of cell communication| |positive regulation of signaling| |regulation of intracellular signal transduction| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp457|Bisphenol F 50μM R08 exp457]]|-2.09| |[[:results:exp501|Methotrexate 0.01μM R08 exp501]]|-1.86| |[[:results:exp446|4-Nitroquinoline-1-oxide 0.5μM R08 exp446]]|-1.85| |[[:results:exp529|Thimerosal 0.85μM R08 exp529]]|-1.8| |[[:results:exp334|All-trans-Retinoic-Acid 40μM R07 exp334]]|-1.79| |[[:results:exp329|Hydroxyurea 100μM R07 exp329]]|-1.71| |[[:results:exp419|Tunicamycin 0.04 to 0.075μM on day4 R07 exp419]]|-1.7| |[[:results:exp142|OICR-9429 10μM R03 exp142]]|2.04| No correlation found to any other genes in chemogenomics.
