The 70-kDa heat shock proteins (Hsp70s) function as molecular chaperones through the allosteric coupling of their nucleotide- and substrate-binding domains, the structures of which are highly conserved. In contrast, the roles of the poorly structured, variable length C-terminal regions present on Hsp70s remain unclear. In many eukaryotic Hsp70s, the extreme(More)
The versatile functions of the heat shock protein 70 (Hsp70) family of molecular chaperones rely on allosteric interactions between their nucleotide-binding and substrate-binding domains, NBD and SBD. Understanding the mechanism of interdomain allostery is essential to rational design of Hsp70 modulators. Yet, despite significant progress in recent years,(More)
Proteins are dynamic entities that populate conformational ensembles, and most functions of proteins depend on their dynamic character. Allostery, in particular, relies on ligand-modulated shifts in these conformational ensembles. Hsp70s are allosteric molecular chaperones with conformational landscapes that involve large rearrangements of their two domains(More)
