HSP82

HSP90, Hsp90 family chaperone HSP82, L000000822, YPL240C
Hsp90 chaperone; redundant in function with Hsc82p; required for pheromone signaling, negative regulation of Hsf1p; docks with Tom70p for mitochondrial preprotein delivery; promotes telomerase DNA binding, nucleotide addition; protein abundance increases in response to DNA replication stress; contains two acid-rich unstructured regions that promote solubility of chaperone-substrate complexes; HSP82 has a paralog, HSC82, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)
PREY

PMT2

FUN25, dolichyl-phosphate-mannose-protein mannosyltransferase PMT2, L000000642, L000001459, YAL023C
Protein O-mannosyltransferase of the ER membrane; transfers mannose residues from dolichyl phosphate-D-mannose to protein serine/threonine residues; involved in ER quality control; acts in a complex with Pmt1p, can instead interact with Pmt5p; antifungal drug target; PMT2 has a paralog, PMT3, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)

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]

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.
