Thr90 phosphorylation of Hsp90α by protein kinase A regulates its chaperone machinery.

Abstract excerpt

Hsp90 (heat-shock protein 90) is one of the most important molecular chaperones in eukaryotes. Hsp90 facilitates the maturation, activation or degradation of its client proteins. It is now well accepted that both ATP binding and co-chaperone association are involved in regulating the Hsp90 chaperone machinery. However, other factors such as post-translational modifications are becoming increasingly recognized as...
