Disrupting progression of the yeast Hsp90 folding pathway at different transition points results in client-specific maturation defects.
Title: Disrupting progression of the yeast Hsp90 folding pathway at different transition points results in client-specific maturation defects.
Mutation or inhibition of Hsp90 resulted in decreased accumulation of Ura2, indicating it is an Hsp90 client. Cpr6 interacted with Ura2 in the absence of stable Cpr6-Hsp90 interaction, suggesting a direct interaction.
Title: Interaction of heat shock protein 90 and the co-chaperone Cpr6 with Ura2, a bifunctional enzyme required for pyrimidine biosynthesis.
Hsc82 is more critical than Hsp82 for growth at 37 degrees C in the absence of mitochondrial DNA.
Title: Hsp90 and mitochondrial proteases Yme1 and Yta10/12 participate in ATP synthase assembly in Saccharomyces cerevisiae.
show that amino-terminal ATP-binding site residue is a conserved, strong regulator of Hsp90 functions, including ATP hydrolysis and chaperone activity.
Title: Hsp90 is regulated by a switch point in the C-terminal domain.
Structural-thermodynamic relationships of interactions in the N-terminal ATP-binding domain of Hsp90.
Title: Structural-thermodynamic relationships of interactions in the N-terminal ATP-binding domain of Hsp90.
Hsp90 prevented the death of calcineurin- and Cmk2-deficient cells.
Title: Nonapoptotic death of Saccharomyces cerevisiae cells that is stimulated by Hsp90 and inhibited by calcineurin and Cmk2 in response to endoplasmic reticulum stresses.
These data support a conserved three-state chaperone cycle where the conformational equilibrium varies between species, implicating evolutionary tuning to meet the particular client protein and metabolic environment of an organism.
Title: Species-dependent ensembles of conserved conformational states define the Hsp90 chaperone ATPase cycle.

Preferred Names: Hsp90 family chaperone HSC82

NP_013911.1

Cytoplasmic chaperone of the Hsp90 family; plays a role in determining prion variants; redundant in function and nearly identical with Hsp82p, and together they are essential; expressed constitutively at 10-fold higher basal levels than HSP82 and induced 2-3 fold by heat shock; contains two acid-rich unstructured regions that promote the solubility of chaperone-substrate complexes; HSC82 has a paralog, HSP82, that arose from the whole genome duplication
