DNA damage signaling downstream of ATM

Research output: Chapter in Book/Report/Conference proceedingChapter


ATM is the apical signaling molecule that triggers diverse cellular responses to double-strand DNA breaks. Directly and indirectly, ATM initiates a two-tiered cascade of protein kinase activation, composed of upstream phosphatidylinositol 3-kinase-like kinases, mediator proteins, and checkpoint kinases. Together, these proteins signal a broad network of downstream effectors that modulate virtually every aspect of cell growth and death. This review will focus on the signaling molecules required for the diverse ATM-dependent responses to DNA damage, with an emphasis on the extensively characterized pathways that suppress proliferation and promote DNA repair.
