CRYSTAL STRUCTURE OF HUMAN CHK2 IN COMPLEX WITH ADP
Overview
The protein kinase Chk2 (checkpoint kinase 2) is a major effector of the, replication checkpoint. Chk2 activation is initiated by phosphorylation of, Thr68, in the serine-glutamine/threonine-glutamine cluster domain (SCD), by ATM. The phosphorylated SCD-segment binds to the FHA domain of a second, Chk2 molecule, promoting dimerisation of the protein and triggering, phosphorylation of the activation segment/T-loop in the kinase domain. We, have now determined the structure of the kinase domain of human Chk2 in, complexes with ADP and a small-molecule inhibitor debromohymenialdisine., The structure reveals a remarkable dimeric arrangement in which T-loops, are exchanged between protomers, to form an active kinase conformation in, trans. Biochemical data suggest that this dimer is the ... [(full description)]
