    Cytoplasmic protein misfolding titrates Hsp70 to activate nuclear Hsf1

    Anna E Masser et al.
    Hsp70 restricts DNA binding activity of Hsf1 to control the width and amplitude of the heat-shock regulon.

    Hsf1 and Hsp70 constitute a two-component feedback loop that regulates the yeast heat shock response

    Joanna Krakowiak et al.
    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.

    HSF-1 activates the ubiquitin proteasome system to promote non-apoptotic developmental cell death in C. elegans

    Maxime J Kinet et al.
    A pathway controlling non-apoptotic developmental cell death engages non-canonical death-promoting activities of the stress factor HSF-1, which, in turn, activates specific components of the ubiquitin-mediated degradation machinery.

    Usf1, a suppressor of the circadian Clock mutant, reveals the nature of the DNA-binding of the CLOCK:BMAL1 complex in mice

    Kazuhiro Shimomura et al.
    A gene that codes for a transcription factor that is involved in lipid and carbohydrate metabolism also has a role in the regulation of circadian rhythms.

    Dynamic control of Hsf1 during heat shock by a chaperone switch and phosphorylation

    Xu Zheng et al.
    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.

    Molecular mechanism of thermosensory function of human heat shock transcription factor Hsf1

    Nikolai Hentze et al.
    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.

    Proteotoxicity from aberrant ribosome biogenesis compromises cell fitness

    Blake W Tye et al.
    Rapidly proliferating cells are at risk of compromised cell fitness due to proteostasis collapse from perturbations that interfere with ribosome biogenesis.
