Cochaperone protein; regulates activity of adenylyl cyclase Cyr1p; involved in kinetochore complex assembly; associates with the SCF (Skp1p/Cdc53p/F box protein) ubiquitin ligase complex; acts as a linker between Skp1p and HSP90 complexes; protein abundance increases in response to DNA replication stress

Dosage Growth Defect

A genetic interaction is inferred when over expression or increased dosage of one gene causes a growth defect in a strain that is mutated or deleted for another gene.

Mutation of essential Hsp90 co-chaperones SGT1 or CNS1 renders yeast hypersensitive to overexpression of other co-chaperones.

Johnson JL, Zuehlke AD, Tenge VR, Langworthy JC

The essential molecular chaperone Hsp90 functions with over ten co-chaperones in Saccharomyces cerevisiae, but the in vivo roles of many of these co-chaperones are poorly understood. Two of these co-chaperones, Cdc37 and Sgt1, target specific types of clients to Hsp90 for folding. Other co-chaperones have general roles in supporting Hsp90 function, but the degree of overlapping or competing functions is ... [more]
