ATM Activation and DNA Damage Response

Abstract excerpt

Well before the gene (ATM) mutated in the human genetic disorder ataxia-telangiectasia (A-T) was described it was evident from the clinical, molecular and cellular phenotype of A-T that this gene would play a central role in the DNA damage response. Mutation of ATM causes defective cell cycle checkpoint activation,a reduced capacity for repair of DNA double strand breaks and abnormal apoptosis, all of which...
