WebIR is a prototypical DNA-damaging agent and IR-induced DNA double-strand breaks (DSBs) are recognized by the DNA damage response (DDR) network of cellular pathways that sense, signal, and repair DNA lesions. WebAug 13, 2004 · The IR-induced intra-S-phase checkpoint reduces RDS. Compared with control cells, Mcph1-inhibited cells showed higher, but variable, RDS when exposed to 5- or 10-Gy irradiation (data not shown), and significantly higher RDS when irradiated with 20 Gy ( Fig. 4A ). This result indicates a role of Mcph1 in the intra-S-phase checkpoint. WebDec 17, 2013 · Finally, we identified six IR-induced phosphorylation sites in BAP1 and showed that mutation of these residues inhibits BAP1 recruitment to DSB sites. We also found that both BAP1 catalytic activity and its phosphorylation are critical for promoting DNA repair and cellular recovery from DNA damage. flaming stsr movie reviews/trailers
