Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.357 | 2.08E-101 | YLR027C | AAT2 | hom | Cytosolic aspartate aminotransferase, involved in nitrogen metabolism; localizes to peroxisomes in oleate-grown cells |
0.348 | 6.11E-96 | YOR001W | RRP6 | hom | Nuclear exosome exonuclease component; has 3'-5' exonuclease activity; involved in RNA processing, maturation, surveillance, degradation, tethering, and export; has similarity to E. coli RNase D and to human PM-Sc1 100 (EXOSC10); mutant displays reduced transcription elongation in the G-less-based run-on (GLRO) assay |
0.344 | 1.05E-93 | 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 |
0.280 | 1.30E-61 | YLR200W | YKE2 | hom | Subunit of the heterohexameric Gim/prefoldin protein complex involved in the folding of alpha-tubulin, beta-tubulin, and actin |
0.262 | 8.36E-54 | 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 |
0.246 | 1.23E-47 | YNL140C_p | YNL140C_p | hom | Protein of unknown function; expressed at both mRNA and protein levels; partially overlaps THO2/YNL139C |
0.195 | 3.35E-30 | 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 |
0.190 | 1.45E-28 | 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 |
0.181 | 3.44E-26 | 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 |
0.174 | 2.33E-24 | YAL047C | SPC72 | hom | Component of the cytoplasmic Tub4p (gamma-tubulin) complex, binds spindle pole bodies and links them to microtubules; has roles in astral microtubule formation and stabilization |
0.169 | 8.19E-23 | YKL007W | CAP1 | hom | Alpha subunit of the capping protein heterodimer (Cap1p and Cap2p); capping protein (CP) binds to the barbed ends of actin filaments preventing further polymerization; localized predominantly to cortical actin patches; protein increases in abundance and relocalizes from bud neck to plasma membrane upon DNA replication stress |
0.167 | 2.28E-22 | YPL017C | IRC15 | hom | Microtubule associated protein; regulates microtubule dynamics; required for accurate meiotic chromosome segregation; null mutant displays large budded cells due to delayed mitotic progression, increased levels of spontaneous Rad52 foci |
0.165 | 7.37E-22 | YML094C-A_d | YML094C-A_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the verified gene GIM5/YML094W; deletion confers sensitivity to GSAO |
0.153 | 4.87E-19 | 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 |
0.141 | 2.52E-16 | YCR064C_d | YCR064C_d | hom | Dubious open reading frame unlikely to encode a protein, based on experimental and comparative sequence data; partially overlaps the verified gene BUD31 |
