DNA damage activates the DNA-PK/ATM/ATR kinases, initiating two parallel cascades that inactivate Cdc2-cyclin B. The first cascade rapidly inhibits progression into mitosis: the CHK kinases phosphorylate and inactivate Cdc25, which can no longer activate Cdc2.

ATM is mutated in patients with AT, a condition with many similar traits to Fanconi anemia.
(Cancer Susceptibility Pathway, NCI Thesaurus/BIOCARTA)
In addition to regulating DNA repair and the cell cycle, ATM can also trigger apoptosis in radiation treated cells.
(ATM Signaling Pathway, NCI Thesaurus/BIOCARTA)
