... as a GET body scaffold. Systematic compositional analyses of GET bodies reveal their chaperone-rich nature and the presence of numerous proteins involved in metabolic processes. Temporal analyses of GET body assembly demonstrate the sequential recruitment of different chaperones, and we discover...

... is promoted by the Hsp90–Cdc37 chaperone complex. Our results show that atp2 Δ cdc28td double-mutant cells, but not single mutants, are sensitive to chemical inhibition of the Hsp90–Cdc37 complex, and exhibit reduced levels of additional Hsp90–Cdc37 client kinases, suggesting an inhibition of this complex...

...Helena M. Schnell; Richard M. Walsh, Jr.; Shaun Rawson; John Hanna ABSTRACT Much of cellular activity is mediated by large multisubunit complexes. However, many of these complexes are too complicated to assemble spontaneously. Instead, their biogenesis is facilitated by dedicated chaperone proteins...

...Sophie Dittmer; Tatjana Kleine; Serena Schwenkert ABSTRACT Molecular chaperones play an important role during the response to different stresses. Since plants are sessile organisms, they need to be able to adapt quickly to different conditions. To do so, plants possess a complex chaperone machinery...

... by structurally related α- and β-subunits. CP biogenesis typically begins with the assembly of the α-ring, which then provides a template for β-subunit integration. In eukaryotes, α-ring assembly is partially mediated by two hetero-dimeric chaperones, termed Pba1–Pba2 (Add66) and Pba3–Pba4 (also known as Irc25...

...Ganapathi Kandasamy; Claes Andréasson ABSTRACT During protein quality control, proteotoxic misfolded proteins are recognized by molecular chaperones, ubiquitylated by dedicated quality control ligases and delivered to the 26S proteasome for degradation. Proteins belonging to the Hsp70 chaperone...

... are present, newly formed aggregates make a relatively small contribution to total aggregate load, and thus the impact of HspB7 is lost. Although HspB7 affected a pre-aggregated structure, surprisingly, the chaperone did not prevent aggregate growth. This implies that HspB7 either affects newly formed...
