J Cell Sci (2022) 135 (8): jcs259622.
Published: 22 April 2022
...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...

Mutation or depletion of the PP1 regulatory subunits Sds22 and Ypi1, which are involved in nuclear targeting of Glc7, also...
