BAIT

DCR2

YLR361C
Phosphoesterase; involved in downregulation of the unfolded protein response (UPR), at least in part via dephosphorylation of Ire1p; dosage-dependent positive regulator of the G1/S phase transition through control of the timing of START
Saccharomyces cerevisiae (S288c)
PREY

TNA1

YGR260W
High affinity nicotinic acid plasma membrane permease; responsible for uptake of low levels of nicotinic acid; expression of the gene increases in the absence of extracellular nicotinic acid or para-aminobenzoate (PABA)

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.

Dcr2 targets Ire1 and downregulates the unfolded protein response in Saccharomyces cerevisiae.

Guo J, Polymenis M

Accumulation of unfolded proteins in the endoplasmic reticulum triggers the unfolded protein response (UPR). How the UPR is downregulated is not well understood. Inositol requirement 1 (Ire1) is an endoplasmic reticulum transmembrane UPR sensor in Saccharomyces cerevisiae. When the UPR is triggered, Ire1 is autophosphorylated, on Ser 840 and Ser 841, inducing the cytosolic endonuclease activity of Ire1, thereby initiating ... [more]
