Dynamics of heat shock protein responses to thermal stress …

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. 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.
