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].

This domain corresponds to the Hsp90 chaperone (Heat shocked protein 90) binding domain of Cdc37 [2]. It is found between the N terminal Cdc37 domain Pfam:PF03234, which is predominantly involved in kinase binding, and the C terminal domain of Cdc37 Pfam:PF08564 whose function is unclear.

This domain corresponds to the N terminal domain which binds predominantly to protein kinases [2] and is found N terminal to the Hsp (Heat shocked protein) 90-binding domain Pfam:PF08565. Expression of a construct consisting of only the N-terminal domain of Saccharomyces pombe Cdc37 results in cellular viability. This indicates that interactions with the cochaperone Hsp90 may not be essential for Cdc37 function [2].
