Super excited to share our latest work on the Hsp70 chaperone code "Mechanosensor-mediated Hsp70 phosphorylation orchestrates the landscape of the heat shock response" out now in Nature Communications: www.nature.com/articles/s41...
Mechanosensor-mediated Hsp70 phosphorylation orchestrates the landscape of the heat shock response - Nature Communications
Cells must sense heat quickly to protect their proteins and membranes. Here, the authors show that membrane stretch detected by the membrane sensor Mid2 promotes rapid phosphorylation of the Hsp70 cha...

Role of Hsp70 chaperone in client-protein folding elucidated by Markov state modeling and NMR restraint-assisted molecular dynamics simulations
Heat shock protein 70 (Hsp70) is a molecular chaperone that plays a key role in cellular processes by assisting protein folding and preventing aggregation. During client-protein folding, Hsp70…

Do you want a pic of the protein or just a deeply conserved alignment? I use this pic from Barton et al text book of HSP70 as eg of deeply conserved protein.

Given all the extra followers. I just wanted to re-introduce our research. All proteins need to be folded into their correct shape and this often needs the help of chaperone proteins such as Hsp70
