Swiss Prot P38532
Scientific Background Heat Shock Factor 1 (HSF1) is a key transcriptional regulator that orchestrates the cellular response to proteotoxic stress by activating genes involved in protein folding, degradation, and quality control. As the primary mediator of the heat shock response, HSF1 binds to heat shock elements (HSEs) in the promoters of heat shock protein (HSP) genes, driving the expression of molecular chaperones essential for maintaining proteostasis.

Structurally, HSF1 contains a conserved N-terminal DNA-binding domain and adjacent hydrophobic repeats critical for trimerization and activation. A second hydrophobic region near the C-terminus suppresses trimer formation under non-stress conditions. In unstressed cells, HSF1 is diffusely localized in the cytoplasm and nucleus. Upon exposure to stressors—such as oxidative damage, heat, or protein misfolding—HSF1 rapidly translocates to nuclear stress granules, initiating a transcriptional program that restores protein homeostasis.

In the context of neurodegenerative diseases, HSF1 plays a pivotal role in mitigating the toxic accumulation of misfolded proteins, a hallmark of disorders such as Alzheimer’s, Parkinson’s, and Huntington’s disease. By enhancing the expression of protective HSPs, HSF1 supports neuronal survival and function under chronic stress conditions. Its dynamic regulation and neuroprotective potential make HSF1 a compelling therapeutic target in neuroscience and neurodegeneration research.
