|---|---|---|---|---|---|
| 0.573 | 3.51E-292 | YDR072C | IPT1 | hom | Inositolphosphotransferase, involved in synthesis of mannose-(inositol-P)2-ceramide (M(IP)2C), the most abundant sphingolipid; can mutate to resistance to the antifungals syringomycin E and DmAMP1 and to K. lactis zymocin |
| 0.500 | 5.38E-212 | YBR036C | CSG2 | hom | Endoplasmic reticulum membrane protein, required for mannosylation of inositolphosphorylceramide and for growth at high calcium concentrations; protein abundance increases in response to DNA replication stress |
| 0.398 | 5.08E-128 | YPL056C_p | LCL1_p | hom | Putative protein of unknown function; deletion mutant is fluconazole resistant and has long chronological lifespan |
| 0.391 | 9.07E-123 | YMR102C_p | YMR102C_p | hom | Protein of unknown function; transcription is activated by paralogous transcription factors Yrm1p and Yrr1p along with genes involved in multidrug resistance; mutant shows increased resistance to azoles; YMR102C is not an essential gene |
| 0.318 | 7.94E-80 | YDR326C | YSP2 | hom | Protein involved in programmed cell death; mutant shows resistance to cell death induced by amiodarone or intracellular acidification; YSP2 has a paralog, YHR080C, that arose from the whole genome duplication |
| 0.314 | 9.78E-78 | YLR055C | SPT8 | hom | Subunit of the SAGA transcriptional regulatory complex but not present in SAGA-like complex SLIK/SALSA, required for SAGA-mediated inhibition at some promoters |
| 0.297 | 3.95E-69 | YGR143W | SKN1 | hom | Protein involved in sphingolipid biosynthesis; type II membrane protein with similarity to Kre6p |
| 0.280 | 2.44E-61 | YNL257C | SIP3 | hom | Transcription cofactor; acts through interaction with DNA-bound Snf1p; C-terminal region has a putative leucine zipper motif; potential Cdc28p substrate; SIP3 has a paralog, YSP1, that arose from the whole genome duplication |
| 0.269 | 1.05E-56 | YJR059W | PTK2 | hom | Putative serine/threonine protein kinase involved in regulation of ion transport across plasma membrane; enhances spermine uptake |
| 0.259 | 2.11E-52 | 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 |
| 0.256 | 1.69E-51 | YOL050C_d | YOL050C_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; overlaps verified gene GAL11; deletion confers sensitivity to 4-(N-(S-glutathionylacetyl)amino) phenylarsenoxide (GSAO) |
| 0.248 | 4.74E-48 | YGL253W | HXK2 | hom | Hexokinase isoenzyme 2; catalyzes phosphorylation of glucose in the cytosol; predominant hexokinase during growth on glucose; functions in the nucleus to repress expression of HXK1 and GLK1 and to induce expression of its own gene; phosphorylation/dephosphorylation at serine-14 by protein kinase Snf1p and protein phosphatase Glc7p-Reg1p regulates nucleocytoplasmic shuttling of Hxk2p; HXK2 has a paralog, HXK1, that arose from the whole genome duplication |
| 0.246 | 1.87E-47 | YKL190W | CNB1 | hom | Calcineurin B; the regulatory subunit of calcineurin, a Ca++/calmodulin-regulated type 2B protein phosphatase which regulates Crz1p (a stress-response transcription factor), the other calcineurin subunit is encoded by CNA1 and/or CMP1; protein abundance increases in response to DNA replication stress |
| 0.239 | 5.77E-45 | YNL229C | URE2 | hom | Nitrogen catabolite repression transcriptional regulator that acts by inhibition of GLN3 transcription in good nitrogen source; has glutathione peroxidase activity and can mutate to acquire GST activity; altered form creates [URE3] prion |
| 0.228 | 6.40E-41 | YNL027W | CRZ1 | hom | Transcription factor, activates transcription of stress response genes; nuclear localization is positively regulated by calcineurin-mediated dephosphorylation; rapidly localizes to the nucleus under blue light stress |
