This entry represents the C-terminal domain of molecular chaperones, or heat shock proteins (Hsps) such as HSP90, which are ubiquitous proteins that act to maintain proper protein folding within the cell. They assist in the folding of nascent polypeptide chains, and are also involved in the refolding of denatured proteins following proteotoxic stress. Five major Hsp families have been determined, and are categorised according to their molecular size (Hsp100, Hsp90, Hsp70, Hsp60, and the small Hsps). Hsps are involved in a variety of cellular processes that are ATP-dependent. Hsp90 chaperones are unique in their ability to regulate a specific subset of cellular signalling proteins that have been implicated in disease processes, including intracellular protein kinases, steroid hormone receptors, and growth factor receptors [1-4].
