Sakurai H and Ota A (2011) Regulation of chaperone gene expression by heat shock transcription factor in Saccharomyces cerevisiae: importance in normal cell growth, stress resistance, and longevity. FEBS Lett 585(17):2744-8
Abstract: Heat shock transcription factor (HSF), a key regulator in the expression of heat shock protein (HSP) chaperones, is involved in the maintenance of protein homeostasis. However, the impact of HSF-mediated transcription of each HSP gene on this process is not fully understood. We show that Saccharomyces cerevisiae cells containing mutations in the HSF-binding sequences of chromosomal HSP90 promoters exhibit various phenotypes, including slow growth, proteotoxic stress sensitivity, and reduced chronological lifespan. Similar phenotypes were observed when HSF-binding sequences in five mitochondrial HSP promoters were mutated. Therefore, HSF-regulated changes in expression of these chaperone genes are necessary to maintain cell viability under various growth conditions.
