ATMSignalingPathway

The ataxia telangiectasia-mutated gene (ATM) encodes a protein kinase that acts as a tumor suppressor. ATM activation by ionizing radiation damage to DNA stimulates DNA repair and blocks progression through the cell cycle. Mutation of the ATM gene causes the disease ataxia telangiectasia which which involves an inherited predisposition to some cancers. To play this role ATM interacts with a broad network of proteins,......阅读全文
