Transcription Regulation of HYPK by Heat Shock Factor 1
HYPK (Huntingtin Yeast Partner K) was originally identified by yeast two-hybrid assay as an interactor of Huntingtin, the protein mutated in Huntington's disease. HYPK was characterized earlier as an intrinsically unstructured protein having chaperone-like activity in vitro and in vivo. HYPK has the ability of reducing rate of aggregate formation and subsequent toxicity caused by mutant Hunting...
متن کاملAntiproliferative prostaglandins activate heat shock transcription factor.
Treatment of human K562 erythroleukemia cells with the antiproliferative prostaglandin A1 results in the elevated transcription of two heat shock genes, HSP70 and HSP90. Parallel with increased heat shock gene transcription is the activation of heat shock transcription factor. Heat shock transcription factor levels are induced within 60 min after prostaglandin A1 addition to levels similar to t...
متن کاملHeat shock factor 1 ameliorates proteotoxicity in cooperation with the transcription factor NFAT.
Heat shock transcription factor 1 (HSF1) is an important regulator of protein homeostasis (proteostasis) by controlling the expression of major heat shock proteins (Hsps) that facilitate protein folding. However, it is unclear whether other proteostasis pathways are mediated by HSF1. Here, we identified novel targets of HSF1 in mammalian cells, which suppress the aggregation of polyglutamine (p...
متن کاملInteraction between Arabidopsis heat shock transcription factor 1 and 70 kDa heat shock proteins.
The activity of the Arabidopsis heat shock transcription factor (HSF) is repressed at normal conditions but activated by cellular stresses. Circumstantial evidence suggests that HSP70 may function as a negative feedback regulator of HSF activity. Here the interaction between HSF and HSP70 is reported using electrophoretic mobility shift and yeast two-hybrid assays. Subdomain mapping indicates a...
متن کاملBeating the heat: A translation factor and an RNA mobilize the heat shock transcription factor HSF1.
Cells respond to stress via orchestrated modifications in gene expression; in a recent publication in Nature, Shamovsky et al. (2006) report that an RNA and a translation factor regulate the activity of a transcriptional activator essential to the mammalian heat shock response.
