Using highly purified proteins, we have identified intermediate reactions that lead to the assembly of molecular chaperone complexes with wild-type or mutant p53R175H protein. Hsp90 possesses higher affinity for wild-type p53 than for the conformational mutant p53R175H. The presence of Hsp90 in a complex with wild-type p53 inhibits the binding of Hsp40 and(More)
