Recruited to sites of DNA damage through interaction with poly(ADP-ribose), a polymeric post-translational modification synthesized transiently at sites of chromosomal damage to accelerate DNA strand break repair reactions. Displays apurinic- apyrimidinic (AP) endonuclease and 3'-5' exonuclease activities in vitro. Also able to introduce nicks at hydroxyuracil and other types of pyrimidine base damage. {ECO:0000269|PubMed:17353262, ECO:0000269|PubMed:17396150}. |zf-CCHH| |positive regulation of DNA ligation| |regulation of DNA ligation| |single strand break repair| |endodeoxyribonuclease activity| |class I DNA-(apurinic or apyrimidinic site) endonuclease activity| |DNA-(apurinic or apyrimidinic site) endonuclease activity| |3-5 exonuclease activity| |regulation of isotype switching| |regulation of immunoglobulin mediated immune response| |regulation of B cell mediated immunity| |site of double-strand break| |nucleotide binding| |regulation of immunoglobulin production| |regulation of DNA recombination| |regulation of production of molecular mediator of immune response| |regulation of adaptive immune response based on somatic recombination of immune receptors built from immunoglobulin superfamily domains| |regulation of lymphocyte mediated immunity| |regulation of adaptive immune response| |double-strand break repair| |positive regulation of DNA metabolic process| |regulation of leukocyte mediated immunity| |regulation of B cell activation| |nucleic acid phosphodiester bond hydrolysis| |regulation of DNA metabolic process| |regulation of immune effector process| |DNA repair| |regulation of lymphocyte activation| |regulation of leukocyte activation| |regulation of cell activation| |DNA metabolic process| |cellular response to DNA damage stimulus| |regulation of immune response| |regulation of immune system process| |cellular response to stress| |positive regulation of nucleobase-containing compound metabolic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp389|PF-06409577 20μM R07 exp389]]|2.07| |[[:results:exp423|Zebularine 20μM R07 exp423]]|2.09| |[[:results:exp316|Geldanamycin 0.015 to 0.025μM on day4 R07 exp316]]|2.2| No correlation found to any other genes in chemogenomics.
