Interaction between the Arabidopsis thaliana heat shock transcription factor HSF1 and the TATA binding protein TBP
Copyright policy )Interaction between the Arabidopsis thaliana heat shock transcription factor HSF1 and the TATA binding protein TBP
The heat shock factor (HSF1) is the central regulator of the heat stress (hs) response and is required for stimulating the transcription of the hs genes and consequently the expression of heat shock proteins. To promote the polymerase II‐dependent transcription of the hs genes, HSF has to communicate with the basal transcription machinery. Here, we report that the Arabidopsis thaliana HSF1 interacts directly with TBP, the general TATA box binding transcription factor, as shown by affinity chromatography and electrophoretic mobility shift analyses in vitro. An in vivo interaction between AtHSF1 and AtTBP1 was suggested by results employing the yeast two‐hybrid system.
