Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.145 | 3.19E-17 | YPL244C | HUT1 | hom | Protein with a role in UDP-galactose transport to the Golgi lumen, has similarity to human UDP-galactose transporter UGTrel1, exhibits a genetic interaction with S. cerevisiae ERO1 |
0.130 | 3.90E-14 | YPL210C | SRP72 | het | Core component of the signal recognition particle (SRP) ribonucleoprotein (RNP) complex that functions in targeting nascent secretory proteins to the endoplasmic reticulum (ER) membrane |
0.128 | 1.19E-13 | YDL045C | FAD1 | het | Flavin adenine dinucleotide (FAD) synthetase, performs the second step in synthesis of FAD from riboflavin |
0.120 | 3.21E-12 | YML130C | ERO1 | het | Thiol oxidase required for oxidative protein folding in the ER; essential for maintaining proper redox balance in ER; feedback regulation of Ero1p occurs via reduction and oxidation of Ero1p regulatory bonds; reduced Pdi1p activates Ero1p by direct reduction of Ero1p regulatory bonds; depletion of thiol substrates and accumulation of oxidized Pdi1p results in inactivation of Ero1p by both Pdi1p-mediated oxidation and autonomous oxidation of Ero1p regulatory bonds |
0.119 | 4.11E-12 | YHL020C | OPI1 | hom | Transcriptional regulator of a variety of genes; phosphorylation by protein kinase A stimulates Opi1p function in negative regulation of phospholipid biosynthetic genes; involved in telomere maintenance |
0.112 | 8.96E-11 | YOR282W_d | YOR282W_d | het | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps essential, verified gene PLP2/YOR281C |
0.096 | 2.26E-8 | YKL051W | SFK1 | hom | Plasma membrane protein that may act together with or upstream of Stt4p to generate normal levels of the essential phospholipid PI4P, at least partially mediates proper localization of Stt4p to the plasma membrane |
0.088 | 2.89E-7 | YER044C | ERG28 | hom | Endoplasmic reticulum membrane protein, may facilitate protein-protein interactions between the Erg26p dehydrogenase and the Erg27p 3-ketoreductase and/or tether these enzymes to the ER, also interacts with Erg6p |
0.088 | 3.22E-7 | YMR161W | HLJ1 | hom | Co-chaperone for Hsp40p, anchored in the ER membrane; with its homolog Ydj1p promotes ER-associated protein degradation (ERAD) of integral membrane substrates; similar to E. coli DnaJ |
0.087 | 4.52E-7 | YDR389W | SAC7 | hom | GTPase activating protein (GAP) for Rho1p, involved in signaling to the actin cytoskeleton, null mutations suppress tor2 mutations and temperature sensitive mutations in actin; potential Cdc28p substrate |
0.085 | 7.58E-7 | YHR127W | YHR127W | hom | Protein of unknown function; localizes to the nucleus; required for asymmetric localization of Kar9p during mitosis |
0.083 | 1.48E-6 | YCL052C | PBN1 | het | Essential component of glycosylphosphatidylinositol-mannosyltransferase I, required for the autocatalytic post-translational processing of the protease B precursor Prb1p, localizes to ER in lumenal orientation; homolog of mammalian PIG-X |
0.080 | 3.54E-6 | YFL031W | HAC1 | hom | Basic leucine zipper (bZIP) transcription factor (ATF/CREB1 homolog); regulates the unfolded protein response, via UPRE binding, and membrane biogenesis; ER stress-induced splicing pathway facilitates efficient Hac1p synthesis; protein abundance increases in response to DNA replication stress |
0.079 | 4.28E-6 | YPR023C | EAF3 | hom | Esa1p-associated factor, nonessential component of the NuA4 acetyltransferase complex, homologous to Drosophila dosage compensation protein MSL3; plays a role in regulating Ty1 transposition |
0.078 | 6.46E-6 | YDR491C_d | YDR491C_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
