WebCytosolic HSP90 requires multiple cochaperones in folding client proteins. However, the function of gp96 (HSP90b1, grp94), an HSP90 paralogue in the endoplasmic reticulum (ER), is believed to be independent of cochaperones. Here, we demonstrate that gp96 chaperones multiple Toll-like receptors (TLRs), but not TLR3, in a manner that is …

WebNov 15, 2010 · The cytosolic heat-shock response, which maintains protein-folding homeostasis in the cytosol, is mediated predominantly by the heat-shock factor (HSF) family of transcription factors ( Fig. 1 ). Similarly to the bacterial response described above, Hsp70 binds to the transactivating domain of HSF1, thus repressing its transcriptional activity. WebNTD is the domain where the binding site for ATP is located and is therefore critical for the ATPase function of the protein. In this domain, there are also binding sites to some co-chaperones including GCUNC-45, p23, P50/Cdc37 and Sgt1 [[30], [31], [32], [33]].It is a α+β sandwich consisting of a folded antiparallel β-sheet at one end and a α-helix group at … dictwriter write header
