Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.105 | 1.01E-9 | YEL055C | POL5 | het | DNA Polymerase phi; has sequence similarity to the human MybBP1A and weak sequence similarity to B-type DNA polymerases, not required for chromosomal DNA replication; required for the synthesis of rRNA |
0.091 | 1.42E-7 | YJL144W | YJL144W | hom | Cytoplasmic hydrophilin essential in dessication-rehydration process; expression induced by osmotic stress, starvation and during stationary phase; protein abundance increases in response to DNA replication stress |
0.090 | 1.54E-7 | YMR137C | PSO2 | hom | Nuclease required for DNA single- and double-strand break repair; acts at a post-incision step in repair of breaks that result from interstrand cross-links produced by a variety of mono- and bi-functional psoralen derivatives; induced by UV-irradiation; forms nuclear foci upon DNA replication stress |
0.089 | 2.12E-7 | YPL266W | DIM1 | het | Essential 18S rRNA dimethylase (dimethyladenosine transferase), responsible for conserved m6(2)Am6(2)A dimethylation in 3'-terminal loop of 18S rRNA, part of 90S and 40S pre-particles in nucleolus, involved in pre-ribosomal RNA processing |
0.085 | 7.08E-7 | YNL272C | SEC2 | het | Guanyl-nucleotide exchange factor for the small G-protein Sec4p; essential for post-Golgi vesicle transport and for autophagy; associates with the exocyst, via exocyst subunit Sec15p, on secretory vesicles |
0.085 | 9.08E-7 | YLR059C | REX2 | hom | 3'-5' RNA exonuclease; involved in 3'-end processing of U4 and U5 snRNAs, 5S and 5.8S rRNAs, and RNase P and RNase MRP RNA; localized to mitochondria and null suppresses escape of mtDNA to nucleus in yme1 yme2 mutants; RNase D exonuclease |
0.084 | 9.68E-7 | YML115C | VAN1 | hom | Component of the mannan polymerase I, which contains Van1p and Mnn9p and is involved in the first steps of mannan synthesis; mutants are vanadate-resistant |
0.083 | 1.63E-6 | YLR434C_d | YLR434C_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the verified ORF TSR2/YLR435W |
0.082 | 2.03E-6 | YDL117W | CYK3 | hom | SH3-domain protein located in the bud neck and cytokinetic actin ring; relocalizes from bud neck to nucleus upon DNA replication stress; activates the chitin synthase activity of Chs2p during cytokinesis; suppressor of growth and cytokinesis defects of chs2 phospho-mutants |
0.081 | 2.43E-6 | YLR088W | GAA1 | het | Subunit of the GPI (glycosylphosphatidylinositol):protein transamidase complex, removes the GPI-anchoring signal and attaches GPI to proteins in the ER |
0.081 | 2.56E-6 | YMR113W | FOL3 | het | Dihydrofolate synthetase, involved in folic acid biosynthesis; catalyzes the conversion of dihydropteroate to dihydrofolate in folate coenzyme biosynthesis |
0.081 | 2.81E-6 | YHR060W | VMA22 | hom | Peripheral membrane protein that is required for vacuolar H+-ATPase (V-ATPase) function, although not an actual component of the V-ATPase complex; functions in the assembly of the V-ATPase; localized to the yeast endoplasmic reticulum (ER) |
0.081 | 2.86E-6 | YNL251C | NRD1 | het | RNA-binding protein, subunit of Nrd1 complex (Nrd1p-Nab3p-Sen1p); complex interacts with the exosome to mediate 3′ end formation of some mRNAs, snRNAs, snoRNAs, and CUTs; interacts with the C-terminal domain of the RNA polymerase II large subunit (Rpo21p), preferentially at phosphorylated Ser5, to direct transcription termination of non-polyadenylated transcripts; H3K4 trimethylation of transcribed regions by Set1p enhances recruitment of Nrd1p to those sites |
0.078 | 5.80E-6 | YNR062C_p | YNR062C_p | hom | Putative membrane protein of unknown function |
0.075 | 1.58E-5 | YGR232W | NAS6 | hom | Proteasome-interacting protein involved in the assembly of the base subcomplex of the 19S proteasomal regulatory particle (RP); ortholog of human oncoprotein gankyrin, which interacts with the Rb tumor suppressor and CDK4/6 |
