CRYSTAL STRUCTURE AND ASSEMBLY OF TSP36, A METAZOAN SMALL HEAT SHOCK PROTEIN
|
OverviewOverview
Small heat shock proteins (sHsps) are oligomers that perform a protective, function by binding denatured proteins. Although ubiquitous, they are of, variable sequence except for a C-terminal approximately 90-residue, "alpha-crystallin domain". Unlike larger stress response chaperones, sHsps, are ATP-independent and generally form polydisperse assemblies. One, proposed mechanism of action involves these assemblies breaking into, smaller subunits in response to stress, before binding unfolding substrate, and reforming into larger complexes. Two previously solved non-metazoan, sHsp multimers are built from dimers formed by domain swapping between the, alpha-crystallin domains, adding to evidence that the smaller subunits are, dimers. Here, the 2.5A resolution structure of an sHsp from the ... [(full description)]
