|---|---|---|---|---|---|
| 0.378 | 2.47E-114 | YNL218W | MGS1 | hom | Protein with DNA-dependent ATPase and ssDNA annealing activities; involved in maintenance of genome; interacts functionally with DNA polymerase delta; homolog of human Werner helicase interacting protein (WHIP); forms nuclear foci upon DNA replication stress |
| 0.323 | 1.70E-82 | YJL171C | YJL171C | hom | GPI-anchored cell wall protein of unknown function; induced in response to cell wall damaging agents and by mutations in genes involved in cell wall biogenesis; sequence similarity to YBR162C/TOS1, a covalently bound cell wall protein; protein abundance increases in response to DNA replication stress |
| 0.317 | 7.41E-79 | YPR180W | AOS1 | het | Subunit of a heterodimeric nuclear SUMO activating enzyme (E1) with Uba2p; activates Smt3p (SUMO) before its conjugation to proteins (sumoylation), which may play a role in protein targeting; essential for viability |
| 0.306 | 1.86E-73 | YNL166C | BNI5 | hom | Protein involved in organization of septins at the mother-bud neck, may interact directly with the Cdc11p septin, localizes to bud neck in a septin-dependent manner |
| 0.292 | 6.65E-67 | YDR521W_d | YDR521W_d | hom | Dubious ORF that overlaps YDR520C; mutant increases expression of PIS1 and RPL3 in glycerol |
| 0.289 | 1.66E-65 | YLL054C_p | YLL054C_p | hom | Putative protein of unknown function with similarity to Pip2p, an oleate-specific transcriptional activator of peroxisome proliferation; YLL054C is not an essential gene |
| 0.275 | 2.85E-59 | 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 |
| 0.273 | 1.67E-58 | 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 |
| 0.273 | 3.21E-58 | YOR152C_p | YOR152C_p | hom | Putative protein of unknown function; YOR152C is not an essential gene |
| 0.271 | 1.82E-57 | YDL157C_p | YDL157C_p | hom | Putative protein of unknown function; the authentic, non-tagged protein is detected in highly purified mitochondria in high-throughput studies |
| 0.255 | 7.81E-51 | YGR022C_d | YGR022C_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; overlaps almost completely with the verified ORF MTL1/YGR023W |
| 0.254 | 3.02E-50 | YDR312W | SSF2 | hom | Protein required for ribosomal large subunit maturation; functionally redundant with Ssf1p; member of the Brix family; SSF2 has a paralog, SSF1, that arose from the whole genome duplication |
| 0.252 | 9.34E-50 | YDL176W | YDL176W | hom | Protein of unknown function, predicted by computational methods to be involved in fructose-1,6-bisphosphatase (Fbp1p) degradation; interacts with components of the GID complex; YDL176W is not an essential gene |
| 0.246 | 1.50E-47 | YFL014W | HSP12 | hom | Plasma membrane protein involved in maintaining membrane organization in stress conditions; induced by heat shock, oxidative stress, osmostress, stationary phase, glucose depletion, oleate and alcohol; protein abundance increased in response to DNA replication stress and dietary restriction; regulated by the HOG and Ras-Pka pathways; required for dietary restriction-induced lifespan extension |
| 0.246 | 1.56E-47 | YDR169C | STB3 | hom | Ribosomal RNA processing element (RRPE)-binding protein; involved in the glucose-induced transition from quiescence to growth; restricted to nucleus in quiescent cells, released into cytoplasm after glucose repletion; binds Sin3p; relative distribution to the nucleus increases upon DNA replication stress |
