WebDec 21, 2001 · While phosphorylation of H2AX in response to HU or UV treatment proofed to be cell cycle-dependent, exposure to IR induced H2AX phosphorylation and foci formation both in S phase and G 1 phase cells (Fig. 2). Together these results suggest that H2AX is phosphorylated at the replication fork in response to replication block. WebMar 16, 2005 · In this study, using Arabidopsisas a model system, we investigated the ATR and ATM dependency of the formation of γ-H2AX foci in M-phase cells exposed to ionizing radiation (IR). We find that although the majority of these foci are ATM-dependent, ∼10% of IR-induced γ-H2AX foci require, instead, functional ATR.
