Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.359 | 1.78E-102 | YLR027C | AAT2 | hom | Cytosolic aspartate aminotransferase, involved in nitrogen metabolism; localizes to peroxisomes in oleate-grown cells |
0.348 | 6.11E-96 | YDR457W | TOM1 | hom | E3 ubiquitin ligase of the hect-domain class; has a role in mRNA export from the nucleus and may regulate transcriptional coactivators; involved in degradation of excess histones; interacts with Dia2p and is required for Dia2p degradation; required to target Cdc6p for ubiquitin-mediated destruction during G1 phase |
0.330 | 4.70E-86 | YDR260C | SWM1 | hom | Subunit of the anaphase-promoting complex, which is an E3 ubiquitin ligase that regulates the metaphase-anaphase transition and exit from mitosis; required for activation of the daughter-specific gene expression and spore wall maturation |
0.284 | 2.09E-63 | YCR063W | BUD31 | hom | Component of the SF3b subcomplex of the U2 snRNP; diploid mutants display a random budding pattern instead of the wild-type bipolar pattern; facilitates passage through G1/S Start, but is not required for G2/M transition or exit from mitosis |
0.279 | 9.36E-61 | YNL140C_p | YNL140C_p | hom | Protein of unknown function; expressed at both mRNA and protein levels; partially overlaps THO2/YNL139C |
0.219 | 1.21E-37 | YLR200W | YKE2 | hom | Subunit of the heterohexameric Gim/prefoldin protein complex involved in the folding of alpha-tubulin, beta-tubulin, and actin |
0.200 | 2.01E-31 | YDR433W_d | YDR433W_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.192 | 3.18E-29 | YDR069C | DOA4 | hom | Ubiquitin isopeptidase, required for recycling ubiquitin from proteasome-bound ubiquitinated intermediates, acts at the late endosome/prevacuolar compartment to recover ubiquitin from ubiquitinated membrane proteins en route to the vacuole |
0.172 | 8.79E-24 | YNL098C | RAS2 | hom | GTP-binding protein that regulates the nitrogen starvation response, sporulation, and filamentous growth; farnesylation and palmitoylation required for activity and localization to plasma membrane; homolog of mammalian Ras proto-oncogenes |
0.169 | 8.57E-23 | YHR041C | SRB2 | hom | Subunit of the RNA polymerase II mediator complex; associates with core polymerase subunits to form the RNA polymerase II holoenzyme; general transcription factor involved in telomere maintenance |
0.165 | 7.18E-22 | YHR209W | CRG1 | hom | S-AdoMet-dependent methyltransferase involved in lipid homeostasis; mediates resistance to a drug cantharidin |
0.163 | 2.68E-21 | YCR077C | PAT1 | hom | Deadenylation-dependent mRNA-decapping factor; also required for faithful chromosome transmission, maintenance of rDNA locus stability, and protection of mRNA 3'-UTRs from trimming; associated with topoisomerase II; functionally linked to Pab1p; forms cytoplasmic foci upon DNA replication stress |
0.152 | 8.77E-19 | YKR024C | DBP7 | hom | Putative ATP-dependent RNA helicase of the DEAD-box family involved in ribosomal biogenesis; essential for growth under anaerobic conditions |
0.149 | 4.11E-18 | YDR392W | SPT3 | hom | Subunit of the SAGA and SAGA-like transcriptional regulatory complexes, interacts with Spt15p to activate transcription of some RNA polymerase II-dependent genes, also functions to inhibit transcription at some promoters |
0.145 | 2.56E-17 | YLL045C | RPL8B | hom | Ribosomal 60S subunit protein L8B; mutation results in decreased amounts of free 60S subunits; homologous to mammalian ribosomal protein L7A, no bacterial homolog; RPL8B has a paralog, RPL8A, that arose from the whole genome duplication |
