Ir-induced foci
Web(IR)-induced foci (IRIF).12 ATM and ATR phosphorylate many of the same substrates, thereby initiating overlapping damage responses although recent evidence suggests that there is specificity as well as overlap in substrate phosphorylation. Of significance, ATM appears to preferentially target the transducer kinase, Chk2, whereas ATR WebFeb 4, 2010 · Discrete nuclear foci that form as a result of H2AX phosphorylation are now widely used as a quantitative marker of individual DSBs. 8 These foci are termed IR …

Web( A, B) Overexpression of USP51, but not its catalytically inactive mutant, suppresses IR-induced 53BP1, BRCA1, and ubiquitin FK2 foci. U2OS cells were transiently transfected with Flag-USP51 or USP51/CI mutants and exposed to 10 Gy of IR. Immunofluorescence using antibodies against the Flag epitope, 53BP1, BRCA1, and FK2 antibody was performed. WebApr 27, 2024 · To determine the impact of SMARCAD1 on repairosome kinetics, we examined IR-induced γ-H2AX, 53BP1, BRCA1, RPA, and RAD51 foci formation by immunofluorescent staining of cells with and without SMARCAD1 depletion (Figure 2).Depletion of SMARCAD1 increased the frequency of irradiated cells with residual γ …
