Charged linker sequence modulates eukaryotic heat shock protein 90 (Hsp90) chaperone activityShinji Tsutsumi
Urologic Oncology Branch, National Cancer Institute, Bethesda, MD 20892, USA
Proc Natl Acad Sci U S A 109:2937-42. 2012..We propose that the charged linker, in addition to providing the flexibility necessary for Hsp90 domain rearrangements--likely its original purpose--has evolved in eukaryotes to serve as a rheostat for the Hsp90 chaperone machine...
