|---|---|---|---|---|---|
| 0.171 | 2.35E-23 | YAL034C-B_d | YAL034C-B_d | het | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data |
| 0.171 | 2.69E-23 | YAL003W | EFB1 | het | Translation elongation factor 1 beta; stimulates nucleotide exchange to regenerate EF-1 alpha-GTP for the next elongation cycle; part of the EF-1 complex, which facilitates binding of aminoacyl-tRNA to the ribosomal A site |
| 0.148 | 6.17E-18 | YGL207W | SPT16 | het | Subunit of the heterodimeric FACT complex (Spt16p-Pob3p), which associates with chromatin via interaction with Nhp6Ap and Nhp6Bp, and reorganizes nucleosomes to facilitate access to DNA by RNA and DNA polymerases; some mutations cause reduced nucleosome occupancy over highly transcribed regions of the yeast genome |
| 0.144 | 4.65E-17 | YNR046W | TRM112 | het | Protein involved in methylation of tRNA, rRNA, and translation factors; subunit of tRNA methyltransferase (MTase) complexes in combination with Trm9p and Trm11p; interacts with and stabilizes 18S rRNA methyltransferase Bud23p; subunit of complex with Mtq2p that methylates Sup45p (eRF1) in the ternary complex eRF1-eRF3-GTP; deletion confers resistance to zymocin; relative distribution to the nucleus increases upon DNA replication stress |
| 0.133 | 1.12E-14 | YBR155W | CNS1 | het | TPR-containing co-chaperone; binds both Hsp82p (Hsp90) and Ssa1p (Hsp70) and stimulates the ATPase activity of SSA1, ts mutants reduce Hsp82p function while over expression suppresses the phenotypes of an HSP82 ts allele and a cpr7 deletion |
| 0.131 | 2.68E-14 | YBR029C | CDS1 | het | Phosphatidate cytidylyltransferase (CDP-diglyceride synthetase); an enzyme that catalyzes that conversion of CTP + phosphate into diphosphate + CDP-diaclglyerol, a critical step in the synthesis of all major yeast phospholipids |
| 0.109 | 2.23E-10 | YBR078W | ECM33 | hom | GPI-anchored protein of unknown function, has a possible role in apical bud growth; GPI-anchoring on the plasma membrane crucial to function; phosphorylated in mitochondria; similar to Sps2p and Pst1p |
| 0.108 | 4.08E-10 | YAR019C | CDC15 | het | Protein kinase of the Mitotic Exit Network; localized to the spindle pole bodies at late anaphase; promotes mitotic exit by directly switching on the kinase activity of Dbf2p; required for spindle disassembly after meiosis II; relocalizes to the cytoplasm upon DNA replication stress |
| 0.095 | 3.18E-8 | YBR038W | CHS2 | het | Chitin synthase II; catalyzes transfer of N-acetylglucosamine (GlcNAc) to chitin upon activation of zymogenic form; required for chitin synthesis in the primary septum during cytokinesis; localization regulated by Cdk1p during mitosis; phosphorylation by Dbf2p kinase regulates its dynamics and chitin synthesis during cytokinesis |
| 0.090 | 1.86E-7 | YJL025W | RRN7 | het | Component of the core factor (CF) rDNA transcription factor complex; CF is required for transcription of 35S rRNA genes by RNA polymerase I and is composed of Rrn6p, Rrn7p, and Rrn11p |

| 0.084 | 9.89E-7 | YER014C-A | BUD25 | hom | Protein involved in bud-site selection; diploid mutants display a random budding pattern instead of the wild-type bipolar pattern |
| 0.083 | 1.69E-6 | YIL003W | CFD1 | het | Highly conserved, iron-sulfur cluster binding protein localized in the cytoplasm; forms a complex with Nbp35p that is involved in iron-sulfur protein assembly in the cytosol |
