ATM-dependent phosphorylation of ATF2 is required for the DNA damage response.Anindita Bhoumik, Shoichi Takahashi, Wolfgang Breitweiser, Y. Shiloh, Nic Jones, Ze'ev A RonaiMolecular cell2005Activating transcription factor 2 (ATF2) is regulated by JNK/p38 in response to stress. Here, we demonstrate that the protein kinase ATM phosphorylates ATF2 on serines 490 and 498 following ionizing… (More)
