WebThese observations raise the possibility that RSS directly act on the HSF1-HSP90 complex, and execute their dissociation. Of note, recent reports have demonstrated that the chemical modifications of Cys 412, 521, and 564 in HSP90 allow the conformational changes of HSP90 protein (41. Shibata T. Kimura Y. Mukai A. Mori H. Web21 okt. 2024 · Notably, this was accompanied by elevated expression of Hsp70 and Hsp90 (Figure 1A). Both of these chaperones are classical markers of the heat shock response, and the corresponding genes are transcriptional targets of HSF1 [32,33]. Accordingly, the transcriptional activity of HSF1 was increased by the removal of PTEN (Figure 1B).
