WebFeb 19, 2024 · Heat shock proteins are a class of molecular chaperone proteins that are produced by the cell in response to stress. 'Stress' could include infection, environmental toxins, cellular damage, oxidative stress (2) or tumours. They recognize incorrectly folded proteins, and work to repair them by unfolding/folding the protein to form its original ... WebHeat shock results in an altered configuration of proteins. This activates the heat-shock transcription factor (HSF), which then activates genes coding for heat-shock proteins (HSPs). HSPs have the general task of correcting the abnormal situation caused by HS-damaged proteins (see Lindquist and Craig, 1988 ). HSF has been localized by Westwood ...
