|---|---|---|---|---|---|
| 0.172 | 9.49E-24 | YPR035W | GLN1 | het | Glutamine synthetase (GS); synthesizes glutamine from glutamate and ammonia; with Glt1p, forms the secondary pathway for glutamate biosynthesis from ammonia; expression regulated by nitrogen source and by amino acid limitation; relocalizes from nucleus to cytoplasmic foci upon DNA replication stress |
| 0.140 | 3.52E-16 | YDL012C | YDL012C | hom | Tail-anchored plasma membrane protein with a conserved CYSTM module; possibly involved in response to stress; may contribute to non-homologous end-joining (NHEJ) based on ydl012c htz1 double null phenotype; YDL012C has a paralog, YBR016W, that arose from the whole genome duplication |
| 0.127 | 1.51E-13 | YIL020C | HIS6 | hom | Phosphoribosyl-5-amino-1-phosphoribosyl-4-imidazolecarboxiamide isomerase, catalyzes the fourth step in histidine biosynthesis; mutations cause histidine auxotrophy and sensitivity to Cu, Co, and Ni salts |
| 0.111 | 1.18E-10 | YNL244C | SUI1 | het | Translation initiation factor eIF1; component of a complex involved in recognition of the initiator codon; modulates translation accuracy at the initiation phase |
| 0.107 | 4.43E-10 | YBR274W | CHK1 | hom | Serine/threonine kinase and DNA damage checkpoint effector, mediates cell cycle arrest via phosphorylation of Pds1p; phosphorylated by checkpoint signal transducer Mec1p; homolog of S. pombe and mammalian Chk1 checkpoint kinase |
| 0.103 | 2.62E-9 | YKL187C | FAT3 | hom | Protein required for fatty acid uptake; Fat3p abundance increases in cortical patches in response to oleate exposure; the authentic, non-tagged protein is detected in a phosphorylated state in highly purified mitochondria in high-throughput studies |
| 0.102 | 2.69E-9 | YLL026W | HSP104 | hom | Disaggregase; heat shock protein that cooperates with Ydj1p (Hsp40) and Ssa1p (Hsp70) to refold and reactivate previously denatured, aggregated proteins; responsive to stresses including: heat, ethanol, and sodium arsenite; involved in [PSI+] propagation; protein becomes more abundant and forms cytoplasmic foci in response to DNA replication stress |
| 0.098 | 1.23E-8 | YGR098C | ESP1 | het | Separase, a caspase-like cysteine protease; promotes sister chromatid separation by mediating dissociation of the cohesin Scc1p from chromatin; inhibits protein phosphatase 2A-Cdc55p to promote mitotic exit; inhibited by Pds1p; relative distribution to the nucleus increases upon DNA replication stress |
| 0.093 | 5.84E-8 | YKL179C | COY1 | hom | Golgi membrane protein with similarity to mammalian CASP; genetic interactions with GOS1 (encoding a Golgi snare protein) suggest a role in Golgi function |
| 0.092 | 9.19E-8 | YOR052C | YOR052C | hom | Nuclear protein of unknown function; expression induced by nitrogen limitation in a GLN3, GAT1-independent manner and by weak acid; transcriptionally regulated by Rpn4p along with proteasome subunit genes; putative ortholog of human AIRAP, which stimulates proteasome activity in response to arsenic; protein abundance increases in response to DNA replication stress |
| 0.091 | 1.38E-7 | YGR077C | PEX8 | hom | Intraperoxisomal organizer of the peroxisomal import machinery; organizes the formation of the importomer complex, bridging the docking complex with the RING finger complex; tightly associated with the lumenal face of the peroxisomal membrane; essential for peroxisome biogenesis; binds PTS1-signal receptor Pex5p, and PTS2-signal receptor Pex7p |
| 0.091 | 1.43E-7 | YJL019W | MPS3 | het | Nuclear envelope protein required for SPB insertion; initiation of SPB duplication and nuclear fusion; acetylation of Mps3p by Eco1p regulates its role in nuclear organization; localizes to the SPB half bridge and at telomeres during meiosis; required with Ndj1p and Csm4p for meiotic bouquet formation and telomere-led rapid prophase movement; N-terminal acetylated by Eco1p |
| 0.090 | 1.96E-7 | YEL019C | MMS21 | het | SUMO ligase and component of the SMC5-SMC6 complex; this complex plays a key role in the removal of X-shaped DNA structures that arise between sister chromatids during DNA replication and repair; mutants are sensitive to methyl methanesulfonate and show increased spontaneous mutation and mitotic recombination |
| 0.088 | 3.46E-7 | YDR010C_d | YDR010C_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data |
| 0.088 | 3.36E-7 | YPL122C | TFB2 | het | Subunit of TFIIH and nucleotide excision repair factor 3 complexes, involved in transcription initiation, required for nucleotide excision repair, similar to 52 kDa subunit of human TFIIH |
