Exposure of cells to various stresses often leads to the induction of a group of proteins called heat shock proteins (HSPs, molecular chaperones). Hsp70 is one of the most highly inducible molecular chaperones, but its expression must be maintained at low levels under physiological conditions to permit constitutive cellular activities to proceed. Heat shock transcription factor 1 (HSF1) is the transcriptional regulator of HSP gene expression, but it remains poorly understood how newly… CONTINUE READING
