摘要

热休克因子(HSF)转录因子家族可驱动基因表达程序,从而维持细胞膜蛋白质的平衡(蛋白稳态),以应对各种生理和外源压力。HSF 功能的重要性已在许多生理和病理环境中得到证实。过去二十年积累的证据表明,HSF 家族驱动的调控程序会因激活的环境不同而发生巨大变化。为了在这些情况下广泛维持蛋白稳态,HSF 必须在正确的时间与正确的靶基因结合并进行适当的调控。在这里,我们将讨论 "热休克因子密码"--我们目前对人类细胞如何利用 HSF 准同源物的多样化和相互作用、局部浓度、翻译后修饰(PTM)以及与其他蛋白质的相互作用来实现细胞在多种环境中的恢复能力所需的功能可塑性的理解。

The heat shock factor code: Specifying a diversity of transcriptional regulatory programs broadly promoting stress resilience
The heat shock factor (HSF) family of transcription factors drives gene expression programs that maintain cytosolic protein homeostasis (proteostasis) in response to a vast array of physiological and exogenous stressors. The importance of HSF function has been demonstrated in numerous physiological and pathological contexts. Evidence accumulating over the last two decades has revealed that the regulatory programs driven by the HSF family can vary dramatically depending on the context in which it is activated. To broadly maintain proteostasis across these contexts, HSFs must bind and appropriately regulate the correct target genes at the correct time. Here, we discuss “the heat shock factor code”—our current understanding of how human cells use HSF paralog diversification and interplay, local concentration, post-translational modifications, and interactions with other proteins to enable the functional plasticity required for cellular resilience across a multitude of environments.

期刊介绍: Cell Stress and Chaperones is an integrative journal that bridges the gap between laboratory model systems and natural populations. The journal captures the eclectic spirit of the cellular stress response field in a single, concentrated source of current information. Major emphasis is placed on the effects of climate change on individual species in the natural environment and their capacity to adapt. This emphasis expands our focus on stress biology and medicine by linking climate change effects to research on cellular stress responses of animals, micro-organisms and plants.
