WebNov 11, 2013 · We could also observe the recruitment of RNF168 to IR-induced foci (IRIF) in the same cells 10 min after irradiation ( Fig. 4 d ). We should note that GFP-RNF168 formed very distinct foci in H2A.X +/+ cells, whereas some background GFP-RNF168 nucleoplasmic staining was noticeable in H2A.X −/− cells, whose foci were somewhat smaller. Webrestored the formation of ionizing radiation-induced foci. Consistent with the biochemical results, the 2.3 A˚ crystal structure of mre11-3 from Pyrococcus furiosus revealed an active site structure with a wild-type-like metal-binding environment.
