Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.121 | 1.97E-12 | YJL159W | HSP150 | hom | O-mannosylated heat shock protein; secreted and covalently attached to the cell wall via beta-1,3-glucan and disulfide bridges; required for cell wall stability; induced by heat shock, oxidative stress, and nitrogen limitation; HSP150 has a paralog, PIR3, that arose from the whole genome duplication |
0.114 | 3.55E-11 | YJL027C_p | YJL027C_p | hom | Putative protein of unknown function |
0.108 | 3.33E-10 | YPL190C | NAB3 | 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; required for termination of non-poly(A) transcripts and efficient splicing |
0.088 | 3.11E-7 | YPL002C | SNF8 | hom | Component of the ESCRT-II complex, which is involved in ubiquitin-dependent sorting of proteins into the endosome; appears to be functionally related to SNF7; involved in glucose derepression |
0.088 | 3.60E-7 | YKL052C | ASK1 | het | Essential subunit of the Dam1 complex (aka DASH complex); couples kinetochores to the force produced by MT depolymerization thereby aiding in chromosome segregation; phosphorylated during the cell cycle by cyclin-dependent kinases; protein abundance increases in response to DNA replication stress |
0.086 | 6.82E-7 | YJR046W | TAH11 | het | DNA replication licensing factor, required for pre-replication complex assembly |
0.084 | 9.84E-7 | YBR143C | SUP45 | het | Polypeptide release factor (eRF1) in translation termination; mutant form acts as a recessive omnipotent suppressor; methylated by Mtq2p-Trm112p in ternary complex eRF1-eRF3-GTP; mutation of methylation site confers resistance to zymocin; has a role in cytokinesis through interaction with Mlc1p |
0.084 | 1.13E-6 | YIL083C | CAB2 | het | Probable phosphopantothenoylcysteine synthetase (PPCS), which catalyzes the second step of coenzyme A biosynthesis from pantothenate; null mutant lethality is complemented by E. coli coaBC (encoding a bifunctional enzyme with PPCS activity) |
0.083 | 1.54E-6 | YKL145W | RPT1 | het | One of six ATPases of the 19S regulatory particle of the 26S proteasome involved in the degradation of ubiquitinated substrates; required for optimal CDC20 transcription; interacts with Rpn12p and Ubr1p; mutant has aneuploidy tolerance |
0.082 | 1.80E-6 | YDR207C | UME6 | hom | Key transcriptional regulator of early meiotic genes, binds URS1 upstream regulatory sequence, couples metabolic responses to nutritional cues with initiation and progression of meiosis, forms complex with Ime1p, and also with Sin3p-Rpd3p |
0.081 | 2.50E-6 | YNL118C | DCP2 | het | Catalytic subunit of the Dcp1p-Dcp2p decapping enzyme complex; removes the 5' cap structure from mRNAs prior to their degradation; nudix hydrolase family member; forms cytoplasmic foci upon DNA replication stress |
0.081 | 2.69E-6 | YKL016C | ATP7 | hom | Subunit d of the stator stalk of mitochondrial F1F0 ATP synthase, which is a large, evolutionarily conserved enzyme complex required for ATP synthesis |
0.079 | 4.45E-6 | YNL085W | MKT1 | hom | Protein that forms a complex with Pbp1p; complex may mediate posttranscriptional regulation of HO; involved in propagation of M2 dsRNA satellite of L-A virus; allelic variation affects mitochondrial genome stability, drug resistance, and more; forms cytoplasmic foci upon DNA replication stress |
0.078 | 6.03E-6 | YNL236W | SIN4 | hom | Subunit of the RNA polymerase II mediator complex; associates with core polymerase subunits to form the RNA polymerase II holoenzyme; contributes to both postive and negative transcriptional regulation; dispensible for basal transcription |
