BAIT
OPT2
YPR194C
Oligopeptide transporter; localized to peroxisomes and affects glutathione redox homeostasis; also localizes to the plasma membrane (PM) and to the late Golgi, and has a role in maintenance of lipid asymmetry between the inner and outer leaflets of the PM; member of the OPT family, with potential orthologs in S. pombe and C. albicans; also plays a role in formation of mature vacuoles and in polarized cell growth

SWI6
PSL8, SDS11, transcriptional regulator SWI6, L000002254, YLR182W
Transcription cofactor; forms complexes with Swi4p and Mbp1p to regulate transcription at the G1/S transition; involved in meiotic gene expression; also binds Stb1p to regulate transcription at START; cell wall stress induces phosphorylation by Mpk1p, which regulates Swi6p localization; required for the unfolded protein response, independently of its known transcriptional coactivators

Synthetic Lethality
A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.
Publication
The yeast oligopeptide transporter Opt2 is localized to peroxisomes and affects glutathione redox homeostasis.
Glutathione, the most abundant small-molecule thiol in eukaryotic cells, is synthesized de novo solely in the cytosol and must subsequently be transported to other cellular compartments. The mechanisms of glutathione transport into and out of organelles remain largely unclear. We show that budding yeast Opt2, a close homolog of the plasma membrane glutathione transporter Opt1, localizes to peroxisomes. We demonstrate ... [more]
