- Description: publisher version , The heat shock protein 40 (Hsp40/DNAJ) family of co-chaperones modulates the activity of the major molecular chaperone heat shock protein 70 (Hsp70) protein group. Hsp40 stimulates the basal ATPase activity of Hsp70 and hence regulates the affinity of Hsp70 for substrate proteins. The number of Hsp40 genes in most organisms is substantially greater than the number of Hsp70 genes. Therefore, different Hsp40 family members may regulate different activities of the same Hsp70. This fact, along with increasing knowledge of the function of Hsp40 in diseases, has led to certain Hsp40 isoforms being considered promising drug targets. Here we review the role of Hsp40 in human disease and recent developments towards the creation of Hsp40-specific inhibitors.

- Description: The Hsp70/Hsp90 organising protein (Hop), also known as stress-inducible protein 1 (STI1), has received considerable attention for diverse cellular functions in both healthy and diseased states. There is extensive evidence that intracellular Hop is a co-chaperone of the major chaperones Hsp70 and Hsp90, playing an important role in the productive folding of Hsp90 client proteins. Consequently, Hop is implicated in a number of key signalling pathways, including aberrant pathways leading to cancer. However, Hop is also secreted and it is now well established that Hop also serves as a receptor for the prion protein, PrPC.
