YG101, Hsp70 family ATPase SSB1, L000002073, L000002508, YDL229W
Cytoplasmic ATPase that is a ribosome-associated molecular chaperone; functions with J-protein partner Zuo1p; may be involved in folding of newly-made polypeptide chains; member of the HSP70 family; interacts with phosphatase subunit Reg1p; SSB1 has a paralog, SSB2, that arose from the whole genome duplication

Phenotypic Suppression

A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Publication

A nuclear export signal prevents Saccharomyces cerevisiae Hsp70 Ssb1p from stimulating nuclear localization signal-directed nuclear transport.

Shulga N, James P, Craig EA, Goldfarb DS

Hsp70 has been implicated in nuclear localization signal (NLS)-directed nuclear transport. Saccharomyces cerevisiae contains distinct SSA and SSB gene families of cytosolic Hsp70s. The nucleocytoplasmic localization of Ssa1p and Ssb1p was investigated using green fluorescent protein (GFP) fusions. Whereas GFP-Ssa1p localized both to the nucleus and cytoplasm, GFP-Ssb1p appeared only in the cytosol. The C-terminal domain of Ssb1p contains a ... [more]

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
