一般描述

ATM (Ataxia Telangiectasia Mutated kinase) and ATR (Ataxia Telangiectasia and Rad3-related kinase) are related kinases that regulate cell cycle checkpoints and DNA repair. ATM is activated in response to DNA damage and serves to arrest further cell division before the damage can be repaired. Mutation in the ATM gene results in the autosomal recessive disease ataxia telangiectasia (AT). The identified substrates for ATM include p53, p95/NBS1, MDM2, Chk2, BRCA1, CtIP, 4E-BP1 and Chk1. ATM activates p53, increasing p21/Cip1/Waf1 levels, thus blocking activation of Cdk2. That results in Rb hypophosphorylation and blockage of the G1/S transition. Separately, ATM also phosphorylates and activates Chk1, which phosphorylates Cdc25C. This inactivates Cdc25C and prevents it from dephosphorylating the inhibitory phosphotyrosine residue on cdc2/Cdk1, thus preventing the G2/M transition. The complex phenotype of cells derived from patients with AT suggests that ATM has additional cellular substrates. In unirradiated cells, ATM is present as an inactive homodimer or multimer. Double-stranded breaks in DNA caused by ionizing radiation cause rapid ATM kinase activation through dissociation of this complex and ATM autophosphorylation at Ser1981.
