HSC82

HSP90, Hsp90 family chaperone HSC82, L000000813, YMR186W
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

CAB2

phosphopantothenate--cysteine ligase CAB2, YIL083C
Subunit of the CoA-Synthesizing Protein Complex (CoA-SPC); subunits of this complex are: Cab2p, Cab3p, Cab4p, Cab5p, Sis2p and Vhs3p; probable phosphopantothenoylcysteine synthetase (PPCS), which catalyzes the second step of coenzyme A biosynthesis from pantothenate; null mutant lethality is complemented by E. coli coaBC (encoding a bifunctional enzyme with PPCS activity)

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

Heterozygous yeast deletion collection screens reveal essential targets of Hsp90.

Franzosa EA, Albanese V, Frydman J, Xia Y, McClellan AJ

Hsp90 is an essential eukaryotic chaperone with a role in folding specific "client" proteins such as kinases and hormone receptors. Previously performed homozygous diploid yeast deletion collection screens uncovered broad requirements for Hsp90 in cellular transport and cell cycle progression. These screens also revealed that the requisite cellular functions of Hsp90 change with growth temperature. We present here for the ... [more]

Ontology Terms

  • vegetative growth (APO:0000106)

Additional Notes

  • A genome-wide chemical-genetic screen was used to identify heterozygous deletion strains whose growth at the hypothermic stress temperature of 15oC was negatively affected when Hsp90 function was compromised using the HSP90-inhibiting drug, macbecin II.
