This gene encodes a DNA repair factor essential for the nonhomologous end-joining pathway, which preferentially mediates repair of double-stranded breaks. Mutations in this gene cause different kinds of severe combined immunodeficiency disorders. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: DNA repair protein involved in DNA nonhomologous end joining (NHEJ) required for double-strand break (DSB) repair and V(D)J recombination. May serve as a bridge between XRCC4 and the other NHEJ factors located at DNA ends, or may participate in reconfiguration of the end bound NHEJ factors to allow XRCC4 access to the DNA termini. It may act in concert with XRCC6/XRCC5 (Ku) to stimulate XRCC4-mediated joining of blunt ends and several types of mismatched ends that are noncomplementary or partially complementary (PubMed:16439204, PubMed:16439205, PubMed:17470781). Binds DNA in a length-dependent manner (PubMed:17317666). {ECO:0000269|PubMed:16439204, ECO:0000269|PubMed:16439205, ECO:0000269|PubMed:17317666, ECO:0000269|PubMed:17470781}. |XLF| |DNA end binding| |DNA ligase IV complex| |positive regulation of ligase activity| |nonhomologous end joining complex| |regulation of ligase activity| |double-strand break repair via nonhomologous end joining| |non-recombinational repair| |B cell differentiation| |fibrillar center| |T cell differentiation| |response to ionizing radiation| |B cell activation| |double-strand break repair| |T cell activation| |lymphocyte differentiation| |leukocyte differentiation| |lymphocyte activation| |response to radiation| |DNA repair| |hemopoiesis| |hematopoietic or lymphoid organ development| |immune system development| |DNA metabolic process| |cellular response to DNA damage stimulus| |leukocyte activation| |central nervous system development| |cell activation| |response to abiotic stimulus| |positive regulation of catalytic activity| |cellular response to stress| |positive regulation of molecular function| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp198|Etoposide 0.1μM R05 exp198]]|-3.75| |[[:results:exp240|Pyridostatin 4μM R05 exp240]]|-3.03| |[[:results:exp360|Genistein 15μM R07 exp360]]|-2.81| |[[:results:exp478|Doxorubicin 0.02μM R08 exp478]]|-2.64| |[[:results:exp318|ABT-702 5μM R07 exp318]]|-1.79| |[[:results:exp504|MK2206 4μM R08 exp504]]|1.79| No correlation found to any other genes in chemogenomics.
