  • Studies also suggest that HSF1 has intrinsic stress-sensing capacity, as both Drosophila and mammalian HSF1 can be converted from a monomer to a homotrimer in vitro in response to thermal or oxidative stress Previous reports demonstrate that the conversion of HSF1 to the high-affinity DNA binding homotrimer is not robust in neuronal cells

  • As such, protein chaperones are often referred to as heat shock proteins, or Hsps. Although the mechanisms for HSF1 activation are incompletely understood, a multistep process occurs in response to stress that involves the interconversion of an inactive cytoplasmic monomer to a homotrimer, nuclear accumulation, DNA binding to HSEs, hyperphosphorylation, and target gene.
