Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.101 | 4.64E-9 | YAL022C | FUN26 | hom | Vacuolar membrane transporter with broad nucleoside selectivity; may regulate balance of nicotinamide riboside (NmR) levels between cytosol and vacuole, contributing to salvage of NmR for use in cytosolic NAD+ synthesis |
0.092 | 9.73E-8 | YJR068W | RFC2 | het | Subunit of heteropentameric Replication factor C (RF-C), which is a DNA binding protein and ATPase that acts as a clamp loader of the proliferating cell nuclear antigen (PCNA) processivity factor for DNA polymerases delta and epsilon |
0.084 | 1.06E-6 | YIL079C | AIR1 | hom | Zinc knuckle protein; involved in nuclear RNA processing and degradation as a component of the TRAMP complex; stimulates the poly(A) polymerase activity of Pap2p in vitro; AIR1 has a paralog, AIR2, that arose from the whole genome duplication |
0.079 | 4.40E-6 | YBR074W_p | YBR074W_p | hom | Putative metalloprotease |
0.078 | 5.77E-6 | YKL096W | CWP1 | hom | Cell wall mannoprotein that localizes specifically to birth scars of daughter cells, linked to a beta-1,3- and beta-1,6-glucan heteropolymer through a phosphodiester bond; required for propionic acid resistance |
0.077 | 8.87E-6 | YGL009C | LEU1 | hom | Isopropylmalate isomerase, catalyzes the second step in the leucine biosynthesis pathway |
0.076 | 9.95E-6 | YBL069W | AST1 | hom | Lipid raft associated protein; interacts with the plasma membrane ATPase Pma1p and has a role in its targeting to the plasma membrane by influencing its incorporation into lipid rafts; sometimes classified in the medium-chain dehydrogenase/reductases (MDRs) superfamily; AST1 has a paralog, AST2, that arose from the whole genome duplication |
0.075 | 1.54E-5 | YBR252W | DUT1 | het | deoxyuridine triphosphate diphosphatase (dUTPase); catalyzes hydrolysis of dUTP to dUMP and PPi, thereby preventing incorporation of uracil into DNA during replication; critical for the maintenance of genetic stability; also has diphosphatase activity on deoxyinosine triphosphate |
0.074 | 1.85E-5 | YGR033C | TIM21 | hom | Nonessential subunit of the Translocase of the Inner Mitochondrial membrane (TIM23 complex); interacts with the Translocase of the Outer Mitochondrial membrane (TOM complex) and with respiratory enzymes; may regulate TIM23 complex activity |
0.074 | 1.97E-5 | YER129W | SAK1 | hom | Upstream serine/threonine kinase for the SNF1 complex; partially redundant with Elm1p and Tos3p; members of this family have functional orthology with LKB1, a mammalian kinase associated with Peutz-Jeghers cancer-susceptibility syndrome |
0.073 | 2.28E-5 | YLR409C | UTP21 | het | Subunit of U3-containing 90S preribosome and Small Subunit (SSU) processome complexes involved in production of 18S rRNA and assembly of small ribosomal subunit; synthetic defect with STI1 Hsp90 cochaperone; human homolog linked to glaucoma |
0.072 | 3.26E-5 | YDR434W | GPI17 | het | Transmembrane protein subunit of the glycosylphosphatidylinositol transamidase complex that adds GPIs to newly synthesized proteins; human PIG-S homolog |
0.070 | 5.26E-5 | YAL055W | PEX22 | hom | Putative peroxisomal membrane protein required for import of peroxisomal proteins, functionally complements a Pichia pastoris pex22 mutation |
0.069 | 5.67E-5 | YDL088C | ASM4 | hom | FG-nucleoporin component of central core of nuclear pore complex (NPC); contributes directly to nucleocytoplasmic transport; induces membrane tubulation, which may contribute to nuclear pore assembly; ASM4 has a paralog, NUP53, that arose from the whole genome duplication |
0.068 | 7.51E-5 | YGR153W_p | YGR153W_p | hom | Putative protein of unknown function |
