They were first identified in relation to heat shock, but are now known to also be expressed during other types of stress such as exposure to cold, UV light, and during wound healing or tissue remodeling. Many members of this group perform chaperone function by Show more…

Figure 37.5 Heat shock proteins (HSP) are so named because they help refold misfolded proteins. In response to increased temperature (a theat shock"), heat shock proteins are activated by release from the NR/HSP complex. At the same time, transcription of HSP genes is activated. Why do you think the cell responds to a heat shock by increasing the activity of proteins that help refold misfolded proteins?
Not all heat shock proteins are chaperones; some are proteins that facilitate the degradation rather than the refolding of other proteins. Explain why the rate of protein degradation might be expected to increase during heat shock. Explain what chaperone proteins do in the cell, and why they are necessary. (What would happen if they weren’t around?)
Adi S.
Protein denaturation can be triggered by a variety of environmental insults, including high temperature, covalent modification, and oxidation. Explain why researchers have observed a correlation between the level of heat shock proteins and the ratio of oxidized to reduced glutathione (see Section 4-3B) in cells subjected to oxidative stress.
