WebThe heat shock response is a cellular activity that increases the number of molecular chaperones to deal with the negative effects on proteins due to increased temperatures, oxidative stress, and heavy metals. In a normal cell, protein homeostasis is maintained because proteins are vital functional units of the cell. WebThe regulation of heat shock gene expression in eukaryotes is mediated by the conserved heat shock transcription factor (HSF). HSF is present in a latent state under normal conditions; it is activated upon heat stress by induction of trimerization and high-affinity binding to DNA and by exposure of domains for transcriptional activity. dfw to heathrowWebHSPs, heat shock factors, stress response, resistance proteins, PCD.
