|---|---|---|---|---|---|
| 0.319 | 8.89E-80 | YDL020C | RPN4 | hom | Transcription factor that stimulates expression of proteasome genes; Rpn4p levels are in turn regulated by the 26S proteasome in a negative feedback control mechanism; RPN4 is transcriptionally regulated by various stress responses; relative distribution to the nucleus increases upon DNA replication stress |
| 0.289 | 1.85E-65 | YBR058C-A | TSC3 | hom | Protein that stimulates the activity of serine palmitoyltransferase (Lcb1p, Lcb2p) several-fold; involved in sphingolipid biosynthesis |
| 0.273 | 4.29E-58 | YOR349W | CIN1 | hom | Tubulin folding factor D involved in beta-tubulin (Tub2p) folding; isolated as mutant with increased chromosome loss and sensitivity to benomyl |
| 0.262 | 1.65E-53 | YPL241C | CIN2 | hom | GTPase-activating protein (GAP) for Cin4p; tubulin folding factor C involved in beta-tubulin (Tub2p) folding; mutants display increased chromosome loss and benomyl sensitivity; deletion complemented by human GAP, retinitis pigmentosa 2 |
| 0.244 | 1.07E-46 | YML124C | TUB3 | hom | Alpha-tubulin; associates with beta-tubulin (Tub2p) to form tubulin dimer, which polymerizes to form microtubules; expressed at lower level than Tub1p; TUB3 has a paralog, TUB1, that arose from the whole genome duplication |
| 0.223 | 4.80E-39 | YMR110C | HFD1 | hom | Hexadecenal dehydrogenase; involved in the conversion of sphingosine 1-phosphate breakdown product hexadecenal to hexadecenoic acid; located in the mitochondrial outer membrane and also in lipid particles; has similarity to ALDH3A2, a human fatty aldehyde dehydrogenase (FALDH) mutated in Sjogren-Larsson syndrome, a neurocutaneous disorder |
| 0.222 | 1.38E-38 | YAL024C | LTE1 | hom | Protein similar to GDP/GTP exchange factors but without detectable GEF activity; required for asymmetric localization of Bfa1p at daughter-directed spindle pole bodies and for mitotic exit at low temperatures |
| 0.218 | 1.75E-37 | YDR527W | RBA50 | het | Protein involved in transcription; interacts with RNA polymerase II subunits Rpb2p, Rpb3, and Rpb11p; has similarity to human RPAP1 |
| 0.218 | 1.92E-37 | YER007W | PAC2 | hom | Microtubule effector required for tubulin heterodimer formation, binds alpha-tubulin, required for normal microtubule function, null mutant exhibits cold-sensitive microtubules and sensitivity to benomyl |
| 0.207 | 1.12E-33 | YOR207C | RET1 | het | Second-largest subunit of RNA polymerase III, which is responsible for the transcription of tRNA and 5S RNA genes, and other low molecular weight RNAs |
| 0.203 | 1.60E-32 | YJL168C | SET2 | hom | Histone methyltransferase with a role in transcriptional elongation; methylates H3 lysine 36, which suppresses incorporation of acetylated histones and signals for the deacetylation of these histones within transcribed genes; associates with the C-terminal domain of Rpo21p; histone methylation activity is regulated by phosphorylation status of Rpo21p |
| 0.202 | 3.72E-32 | YPR146C_d | YPR146C_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
| 0.193 | 1.59E-29 | YMR185W | RTP1 | het | Protein required for the nuclear import and biogenesis of RNA pol II; conflicting evidence on whether null mutant is viable with elongated buds, or inviable; interacts with Rpb2, Rpb3, Nup116p, Nup100p and components of the R2TP complex (Rvb1p, Rvb2p, Pih1p); similar to human TMCO7 gene |
| 0.193 | 2.61E-29 | YLR243W | GPN3 | het | Putative GTPase with a role in biogenesis of RNA pol II and polIII; may be involved in assembly of RNA polymerases II and III and in their transport into the nucleus; contains a Gly-Pro-Asn motif in the G domain; similar to Npa3p and Gpn2p |
| 0.192 | 3.54E-29 | YDR485C | VPS72 | hom | Htz1p-binding component of the SWR1 complex, which exchanges histone variant H2AZ (Htz1p) for chromatin-bound histone H2A; required for vacuolar protein sorting |
