    The translation elongation factor eEF1A1 couples transcription to translation during heat shock response

    Maria Vera, Bibhusita Pani ... Evgeny Nudler
    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.

    Diversification of the Caenorhabditis heat shock response by Helitron transposable elements

    Jacob M Garrigues, Brian V Tsu ... Amy E Pasquinelli
    Helitron transposable elements, by providing high density transcription factor binding sites upstream of host genes, have diversified the heat shock response within and among Caenorhabditis species.

    Heat Shock Factor 1 forms nuclear condensates and restructures the yeast genome before activating target genes

    Linda S Rubio, Suman Mohajan, David S Gross
    In response to ethanol stress, the yeast transcription factor Hsf1 forms nuclear condensates and drives the coalescence of target genes prior to their transcriptional activation while in response to thermal stress these three phenomena are tightly coordinated.

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

    Xu Zheng, Joanna Krakowiak ... David Pincus
    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.

    Host proteostasis modulates influenza evolution

    Angela M Phillips, Luna O Gonzalez ... Matthew D Shoulders
    Host protein homeostasis is a critical force shaping influenza evolution, impacting both the nature of selection on the influenza genome and the accessibility of specific mutational trajectories.

    Transient intracellular acidification regulates the core transcriptional heat shock response

    Catherine G Triandafillou, Christopher D Katanski ... D Allan Drummond
    When translation stops, cells require intracellular acidification to turn on the conserved heat shock response during stress, and stress-triggered acidification (common in eukaryotes) is adaptive, promoting cell and population fitness.

    A ribosome assembly stress response regulates transcription to maintain proteome homeostasis

    Benjamin Albert, Isabelle C Kos-Braun ... David Shore
    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.

    Cytoplasmic protein misfolding titrates Hsp70 to activate nuclear Hsf1

    Anna E Masser, Wenjing Kang ... Claes Andréasson
    Hsp70 restricts DNA binding activity of Hsf1 to control the width and amplitude of the heat-shock regulon.

    Spatial sequestration and detoxification of Huntingtin by the ribosome quality control complex

    Junsheng Yang, Xinxin Hao ... Thomas Nyström
    A genome-wide screen in yeast reveals that key proteins in ribosome quality control also regulate mutant Huntingtin aggregation and toxicity.
