Protein

Hsp70/Hsp90 co-chaperone CNS1

Gene

CNS1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Co-chaperone that binds to the molecular chaperones Hsp90 (HSC82 and HSP82) and Hsp70 (SSA1). Stimulates SSA1 ATPase activity, but not Hsp90 ATPase activity. Involved in only a subset of Hsp90 functions.2 Publications
