Abstract
The Small Heat-Shock Proteins (sHSPs) are a widespread family of molecular chaperones that tend to populate ensembles of inter-converting conformational and oligomeric states at equilibrium. How this dynamic structure is linked to the sHSPs’ ability to rapidly bind and sequester target proteins, intercepting them en route to aggregation and deposition during disease and cellular stress, is a controversial topic. Partly this is because the dynamics of the sHSPs pose challenges to all biophysical and structural biology techniques, rendering them difficult to study. Here we give a personal view on recent insights that have been obtained on the dynamic motions these proteins undergo, their regulation in the cell, and hypothesise on how they may directly underpin sHSP activity.
