Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.152 | 6.97E-19 | YGR201C_p | YGR201C_p | hom | Putative protein of unknown function |
0.151 | 1.61E-18 | YNL104C | LEU4 | hom | Alpha-isopropylmalate synthase (2-isopropylmalate synthase); the main isozyme responsible for the first step in the leucine biosynthesis pathway; LEU4 has a paralog, LEU9, that arose from the whole genome duplication |
0.144 | 5.08E-17 | YDR042C_p | YDR042C_p | hom | Putative protein of unknown function; expression is increased in ssu72-ts69 mutant |
0.132 | 1.85E-14 | YML108W | YML108W | hom | Protein of unknown function; structure defines a new subfamily of the split beta-alpha-beta sandwiches; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm and nucleus; YML108W is not an essential gene; relative distribution to the nucleus increases upon DNA replication stress |
0.131 | 2.13E-14 | YKL030W_d | YKL030W_d | hom | Dubious open reading frame, unlikely to encode a protein; not conserved in closely related Saccharomyces species; partially overlaps the verified gene MAE1 |
0.126 | 2.44E-13 | YDR306C_p | YDR306C_p | hom | F-box protein of unknown function; interacts with Sgt1p via a Leucine-Rich Repeat (LRR) domain |
0.120 | 3.13E-12 | YDR277C | MTH1 | hom | Negative regulator of the glucose-sensing signal transduction pathway, required for repression of transcription by Rgt1p; interacts with Rgt1p and the Snf3p and Rgt2p glucose sensors; phosphorylated by Yck1p, triggering Mth1p degradation |
0.117 | 1.04E-11 | YMR140W | SIP5 | hom | Protein of unknown function; interacts with both the Reg1p/Glc7p phosphatase and the Snf1p kinase; forms cytoplasmic foci upon DNA replication stress |
0.116 | 1.44E-11 | YBR205W | KTR3 | hom | Putative alpha-1,2-mannosyltransferase; involved in O- and N-linked protein glycosylation; member of the KRE2/MNT1 mannosyltransferase family; Svp26p mediates uptake of Ktr3p into COPII vesicles; relocalizes from nucleus to vacuole upon DNA replication stress |
0.113 | 4.99E-11 | YDR420W | HKR1 | hom | Mucin family member that functions as an osmosensor in the Sho1p-mediated HOG pathway with Msb2p; proposed to be a negative regulator of filamentous growth; mutant displays defects in beta-1,3 glucan synthesis and bud site selection |
0.113 | 5.16E-11 | YGR096W | TPC1 | hom | Mitochondrial membrane transporter that mediates uptake of the essential cofactor thiamine pyrophosphate (ThPP) into mitochondria; expression appears to be regulated by carbon source; member of the mitochondrial carrier family |
0.108 | 3.95E-10 | YLR154C | RNH203 | hom | Ribonuclease H2 subunit, required for RNase H2 activity; related to human AGS3 that causes Aicardi-Goutieres syndrome |
0.106 | 6.55E-10 | YLR394W | CST9 | hom | SUMO E3 ligase; required for synaptonemal complex formation; localizes to synapsis initiation sites on meiotic chromosomes; potential Cdc28p substrate |
0.105 | 1.21E-9 | YLR237W | THI7 | hom | Plasma membrane transporter responsible for the uptake of thiamine, member of the major facilitator superfamily of transporters; mutation of human ortholog causes thiamine-responsive megaloblastic anemia |
0.101 | 3.96E-9 | YLR287C_p | YLR287C_p | hom | Putative protein of unknown function; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm; YLR287C is not an essential gene |
