In molecular biology, molecular chaperones are proteins that assist the conformational folding or unfolding of large proteins or macromolecular protein complexes. There are a number of classes of molecular … See more

In human cell lines, chaperone proteins were found to compose ~10% of the gross proteome mass, and are ubiquitously and highly expressed … See more

The genes of bacteriophage (phage) T4 that encode proteins with a role in determining phage T4 structure were identified using conditional lethal mutants. Most of these … See more

There are many disorders associated with mutations in genes encoding chaperones (i.e. multisystem proteinopathy) that can affect muscle, bone … See more

Many chaperones are heat shock proteins, that is, proteins expressed in response to elevated temperatures or other cellular stresses. Heat shock … See more

There are many different families of chaperones; each family acts to aid protein folding in a different way. In bacteria like E. coli, many of these proteins are highly expressed under conditions of high stress, for example, when the bacterium is placed in high … See more

The investigation of chaperones has a long history. The term "molecular chaperone" appeared first in the literature in 1978, and was invented by Ron Laskey to describe the ability … See more
