Webb4 okt. 2005 · Small heat-shock proteins (sHsps) are a widespread and diverse class of molecular chaperones. Recent evidence suggests that they maintain protein homeostasis by binding proteins in non-native... WebbHere we show that heat stroke triggers pervasive necrotic cell death and neurodegeneration in Caenorhabditis elegans. Preconditioning of animals at a mildly elevated temperature strongly protects from heat-induced necrosis. The heat-shock transcription factor HSF-1 and the small heat-shock protein HSP-16.1 mediate …

Webb16 maj 2003 · The ubiquitous small heat shock proteins (sHsps) are efficient molecular chaperones that interact with nonnative proteins, prevent their aggregation, and support subsequent refolding. No obvious substrate specificity has been detected so far. A striking feature of sHsps is that they form large complexes with nonnative proteins. Webb30 juli 1998 · The sHSPs can form large multimeric structures and have a wide range of cellular functions, including endowing cells with thermotolerance in vivo and being able …
Webb14 mars 2024 · Cells employ a well-preserved physiological stress response mechanism, termed the heat shock response, to activate a certain type of molecular chaperone called heat shock proteins (HSPs). HSPs are activated by transcriptional activators of heat shock genes known as heat shock factors (HSFs).
Webb6 apr. 2024 · The human genome encodes ten small heat shock proteins (sHSPs), called HSPB1 through HSPB10, some of which are ubiquitously expressed, while others show tissue specificity.
