Proteolytic mapping of heat shock transcription factor domains [PDF]

Protein Science, 1996
AbstractHeat shock transcription factors (HSFs) of higher eukaryotes respond to physical and cellular stress signals by tri‐merizing, binding to a specific site on DNA, and transactivating genes encoding the heat shock proteins. In this work, limited proteolysis was used as a biochemical probe of the domain organization of Drosophila HSF.

Phosphorylation of Drosophila heat shock transcription factor

Cell Stress & Chaperones, 1999
The role that phosphorylation plays in regulating heat shock factor (HSF) function and activity has been the subject of several studies. Here, we demonstrate that Drosophila melanogaster HSF (DmHSF) is a phosphoprotein that is multiply phosphorylated at some sites and is dephosphorylated at others upon heat shock.

Heat Shock Factor Is Involved in Regulating the Transcriptional Expression of Two Potential Hsps (AhHsp70 and AhsHsp21) and Its Role in Heat Shock Response of Agasicles hygrophila

Frontiers in Physiology, 2020
Heat shock proteins are molecular chaperones that are involved in numerous normal cellular processes and stress responses, and heat shock factors are transcriptional activators of heat shock proteins.

Heat shock transcription factors (Hsfs) in Taraxacum kok-saghyz Rodin: Identification, classification, phylogeny and expression analysis

Current Plant Biology, 2023
The Heat Shock Transcription Factor (Hsf) serves as a critical transcription factor in plants, exerting its function by binding to specific promoter regions in response to heat stress.

Complex Regulation of the Yeast Heat Shock Transcription Factor [PDF]

Molecular Biology of the Cell, 2000
The yeast heat shock transcription factor (HSF) is regulated by posttranslational modification. Heat and superoxide can induce the conformational change associated with the heat shock response. Interaction between HSF and the chaperone hsp70 is also thought to play a role in HSF regulation.

Genome-wide transcriptional profiles during temperature and oxidative stress reveal coordinated expression patterns and overlapping regulons in rice. [PDF]

PLoS ONE, 2012
Genome wide transcriptional changes by cold stress, heat stress and oxidative stress in rice seedlings were analyzed. Heat stress resulted in predominant changes in transcripts of heat shock protein and heat shock transcription factor genes, as well as ...

Transcriptome analysis of Clematis lanuginosa: Novel features of the molecular events occurring under heat-shock stress

Ornamental Plant Research, 2022
The weak heat tolerance of Clematis ornamental varieties negatively affects their ornamental qualities in the summer. To elucidate heat resistance mechanisms, Clematis lanuginosa, which is an important original parent of the Clematis large-flowered group

Modulation of tolerance by mutant heat shock transcription factors [PDF]

Cell Stress & Chaperones, 1999
It ought to be possible to recruit normal cellular defenses to mitigate ischemia/reperfusion damage and to reduce toxicity of chemotherapeutic drugs. Stress-preconditioned cells acquire a tolerant state characterized by increased resistance to such insults. This state is widely believed to be mediated, partially, by heat shock proteins (Hsps). Indirect

Heat shock stimulation of a tilapia heat shock protein 70 promoter is mediated by a distal element [PDF]

, 2001
peer reviewedWe reported previously that a tilapia (Oreochromis mossambicus) heat shock protein 70 (HSP70) promoter is able to confer heat shock response on a reporter gene after transient expression both in cell culture and in microinjected zebrafish ...
