Hsp70 proteins are central components of the cellular network of molecular chaperones and
folding catalysts. They assist a large variety of protein folding processes in the cell by …

An essential cellular machinery that has been identified and studied only relatively recently
is a collective of specialized proteins, molecular chaperones, that bind nonnative states of …

Heat shock 70 kDa proteins (HSP70s) are ubiquitous molecular chaperones that function in
a myriad of biological processes, modulating polypeptide folding, degradation and …

▪ Abstract Recent years have witnessed dramatic advances in our understanding of how
newly translated proteins fold in the cell and the contribution of molecular chaperones to this …

The folding of most newly synthesized proteins in the cell requires the interaction of a variety
of protein cofactors known as molecular chaperones. These molecules recognize and bind …

Biomolecules are in constant motion. To understand how they function, and why
malfunctions can cause disease, it is necessary to describe their three-dimensional …

Hsp70 chaperones are central hubs of the protein quality control network and collaborate
with co-chaperones having a J-domain (an∼ 70-residue–long helical hairpin with a flexible …

Efficient targeting of Hsp70 chaperones to substrate proteins depends on J-domain
cochaperones, which in synergism with substrates trigger ATP hydrolysis in Hsp70s and …

It is a general feature of molecular chaperones that they are highly conserved throughout
evolution. Prokaryotic and eukaryotic Hsp70 proteins, for example, are over 50% identical at …

SUMMARY α-Crystallins were originally recognized as proteins contributing to the
transparency of the mammalian eye lens. Subsequently, they have been found in many, but …
