Heat shock induces relocalization of epigenetic modifiers to the nucleolus, which acts as a dedicated protein quality control center that is indispensable for recovery of epigenetic regulators and epigenetic modifications.
Dynamic regulation of the heat shock response depends on a negative feedback loop in which Hsf1 activates expression of Hsp70 and Hsp70 specifically and directly represses Hsf1 transactivation.
Quantitative dissection of the roles of chaperone binding and phosphorylation in regulating heat shock factor 1 leads to a predictive model of the dynamics of the yeast heat shock response.
Heat-induced local unfolding allows Hsf1 to form trimers and bind to DNA, which depends on Hsf1 concentration and is promoted, not inhibited, by Hsp90.
Multiple iso-energetic-specific interactions involving the intrinsically-disordered region of sHSP HSPB1 define a quasi-ordered state, providing insights into inherited disease-associated mutations within the region that are thought to be disordered.
Eukaryotic translation elongation factor 1A1 controls the process of heat shock response, from transcriptional activation of the HSP70 gene, to HSP70 mRNA stabilization, nuclear export, and translation.
Ribosome assembly is monitored to promote proteostatis through a system whereby unassembled ribosomal proteins lead to activation of heat shock factor 1 and inactivation of the RP gene activator Ifh1.
Small decreases in pH associated with cellular stress conditions unleash a cryptic mode of client binding in a ubiquitously expressed human small heat shock protein that is more effective at delaying client aggregation.
