Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.289 | 2.24E-65 | YBR091C | TIM12 | het | Essential protein of the inner mitochondrial membrane, peripherally localized; component of the TIM22 complex, which is a twin-pore translocase that mediates insertion of numerous multispanning inner membrane proteins |
0.265 | 5.85E-55 | YER165W | PAB1 | het | Poly(A) binding protein, part of the 3'-end RNA-processing complex, mediates interactions between the 5' cap structure and the 3' mRNA poly(A) tail, involved in control of poly(A) tail length, interacts with translation factor eIF-4G |
0.248 | 2.97E-48 | YNR016C | ACC1 | het | Acetyl-CoA carboxylase, biotin containing enzyme; catalyzes the carboxylation of cytosolic acetyl-CoA to form malonyl-CoA and regulates histone acetylation by regulating the availablity of acetyl-CoA; required for de novo biosynthesis of long-chain fatty acids; |
0.245 | 3.14E-47 | YDL140C | RPO21 | het | RNA polymerase II largest subunit B220, part of central core; phosphorylation of C-terminal heptapeptide repeat domain regulates association with transcription and splicing factors; similar to bacterial beta-prime |
0.244 | 1.63E-46 | YJL081C | ARP4 | het | Nuclear actin-related protein involved in chromatin remodeling, component of chromatin-remodeling enzyme complexes |
0.234 | 5.86E-43 | YPR104C | FHL1 | het | Regulator of ribosomal protein (RP) transcription; has forkhead associated domain that binds phosphorylated proteins; recruits coactivator Ifh1p or corepressor Crf1p to RP gene promoters; also has forkhead DNA-binding domain though in vitro DNA binding assays give inconsistent results; computational analyses suggest it binds DNA directly at highly active RP genes and indirectly through Rap1p motifs at others; suppresses RNA pol III and splicing factor prp4 mutants |
0.233 | 9.87E-43 | YBL026W | LSM2 | het | Lsm (Like Sm) protein; part of heteroheptameric complexes (Lsm2p-7p and either Lsm1p or 8p): cytoplasmic Lsm1p complex involved in mRNA decay; nuclear Lsm8p complex part of U6 snRNP and possibly involved in processing tRNA, snoRNA, and rRNA; relocalizes from nucleus to cytoplasmic foci upon DNA replication stress |
0.225 | 1.21E-39 | YOR236W | DFR1 | het | Dihydrofolate reductase involved in tetrahydrofolate biosynthesis; required for respiratory metabolism |
0.221 | 2.43E-38 | YDR172W | SUP35 | het | Translation termination factor eRF3, has a role in mRNA deadenylation and decay; altered protein conformation creates the [PSI(+)] prion that alters translational fidelity and results in a nonsense suppressor phenotype |
0.219 | 9.95E-38 | YLL043W | FPS1 | hom | Plasma membrane channel, member of major intrinsic protein (MIP) family; involved in efflux of glycerol and in uptake of acetic acid and the trivalent metalloids arsenite and antimonite; phosphorylated by Hog1p MAPK under acetate stress |
0.210 | 6.50E-35 | YLR321C | SFH1 | het | Component of the RSC chromatin remodeling complex; essential gene required for cell cycle progression and maintenance of proper ploidy; phosphorylated in the G1 phase of the cell cycle; Snf5p paralog |
0.207 | 1.09E-33 | YLR033W | RSC58 | het | Component of the RSC chromatin remodeling complex; RSC functions in transcriptional regulation and elongation, chromosome stability, and establishing sister chromatid cohesion; involved in telomere maintenance |
0.200 | 1.45E-31 | YLR424W | SPP382 | het | Essential protein that forms a dimer with Ntr2p; also forms a trimer, with Ntr2p and Prp43p, that is involved in spliceosome disassembly; found also in a multisubunit complex with the splicing factor Clf1p; suppressor of prp38-1 mutation |
0.200 | 1.65E-31 | YGL093W | SPC105 | het | Subunit of a kinetochore-microtubule binding complex with Kre28p that bridges centromeric heterochromatin and kinetochore MAPs and motors; required for sister chromatid bi-orientation and kinetochore binding of SAC components |
0.195 | 5.24E-30 | YNL271C | BNI1 | hom | Formin, nucleates the formation of linear actin filaments, involved in cell processes such as budding and mitotic spindle orientation which require the formation of polarized actin cables, functionally redundant with BNR1 |
