COMPLEX OF HSP90 AND P50
Overview
Recruitment of protein kinase clients to the Hsp90 chaperone involves the, cochaperone p50(cdc37) acting as a scaffold, binding protein kinases via, its N-terminal domain and Hsp90 via its C-terminal region. p50(cdc37) also, has a regulatory activity, arresting Hsp90's ATPase cycle during, client-protein loading. We have localized the binding site for p50(cdc37), to the N-terminal nucleotide binding domain of Hsp90 and determined the, crystal structure of the Hsp90-p50(cdc37) core complex. Dimeric p50(cdc37), binds to surfaces of the Hsp90 N-domain implicated in ATP-dependent, N-terminal dimerization and association with the middle segment of the, chaperone. This interaction fixes the lid segment in an open conformation, inserts an arginine side chain into the ATP binding pocket to disable, catalysis, and prevents trans-activating interaction of the N domains.
