|---|---|---|---|---|---|
| 0.355 | 2.82E-100 | YLR021W | IRC25 | hom | Component of a heterodimeric Poc4p-Irc25p chaperone involved in assembly of alpha subunits into the 20S proteasome; may regulate formation of proteasome isoforms with alternative subunits under different conditions |
| 0.318 | 1.09E-79 | YER041W | YEN1 | hom | Holliday junction resolvase; localization is cell-cycle dependent and regulated by Cdc28p phosphorylation; homolog of human GEN1 and has similarity to S. cerevisiae endonuclease Rth1p |
| 0.313 | 5.24E-77 | YPR146C_d | YPR146C_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
| 0.309 | 3.63E-75 | YFR007W | YFH7 | hom | Putative kinase with similarity to the phosphoribulokinase/uridine kinase/bacterial pantothenate kinase (PRK/URK/PANK) subfamily of P-loop kinases |
| 0.303 | 3.73E-72 | YMR022W | UBC7 | hom | Ubiquitin conjugating enzyme, involved in the ER-associated protein degradation pathway; requires Cue1p for recruitment to the ER membrane; proposed to be involved in chromatin assembly |
| 0.296 | 8.79E-69 | YJL155C | FBP26 | hom | Fructose-2,6-bisphosphatase, required for glucose metabolism; protein abundance increases in response to DNA replication stress |
| 0.292 | 6.96E-67 | YBL041W | PRE7 | het | Beta 6 subunit of the 20S proteasome |
| 0.289 | 2.15E-65 | YJL193W_p | YJL193W_p | hom | Putative protein of unknown function, predicted to encode a triose phosphate transporter subfamily member based on phylogenetic analysis; similar to YOR307C/SLY41; deletion mutant has a respiratory growth defect |
| 0.285 | 8.79E-64 | YFR050C | PRE4 | het | Beta 7 subunit of the 20S proteasome |
| 0.280 | 1.36E-61 | YER094C | PUP3 | het | Beta 3 subunit of the 20S proteasome involved in ubiquitin-dependent catabolism; human homolog is subunit C10 |
| 0.280 | 2.59E-61 | YDL183C | YDL183C | hom | Mitochondrial inner-membrane protein thought to be involved in the formation of an active mitochondrial K+/H+ exchanger (KHE) system; non-essential gene |
| 0.279 | 6.02E-61 | YML014W | TRM9 | hom | tRNA methyltransferase; catalyzes modification of wobble bases in tRNA anticodons to 2, 5-methoxycarbonylmethyluridine and 5-methoxycarbonylmethyl-2-thiouridine; may act as part of a complex with Trm112p; deletion mutation increases translational infidelity, including amino acid misincorporation and -1 frameshifting, and also confers resistance to zymocin; null mutant displays activation of stress responses |
| 0.277 | 2.81E-60 | YDR537C_d | YDR537C_d | hom | Dubious open reading frame unlikely to encode a protein, almost completely overlaps verified ORF PAD1/YDR538W |
| 0.273 | 1.90E-58 | YMR314W | PRE5 | het | Alpha 6 subunit of the 20S proteasome; protein abundance increases in response to DNA replication stress |
| 0.268 | 3.72E-56 | YOL038W | PRE6 | het | Alpha 4 subunit of the 20S proteasome; may replace alpha 3 subunit (Pre9p) under stress conditions to create a more active proteasomal isoform; GFP-fusion protein relocates from cytosol to the mitochondrial surface upon oxidative stress |
