Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.142 | 1.18E-16 | YJL136C | RPS21B | hom | Protein component of the small (40S) ribosomal subunit; homologous to mammalian ribosomal protein S21, no bacterial homolog; RPS21B has a paralog, RPS21A, that arose from the whole genome duplication |
0.138 | 9.39E-16 | YOR078W | BUD21 | hom | Component of small ribosomal subunit (SSU) processosome that contains U3 snoRNA; originally isolated as bud-site selection mutant that displays a random budding pattern |
0.134 | 6.62E-15 | YOL121C | RPS19A | hom | Protein component of the small (40S) ribosomal subunit; required for assembly and maturation of pre-40 S particles; homologous to mammalian ribosomal protein S19, no bacterial homolog; mutations in human RPS19 are associated with Diamond Blackfan anemia; RPS19A has a paralog, RPS19B, that arose from the whole genome duplication |
0.130 | 4.33E-14 | YLR048W | RPS0B | hom | Protein component of the small (40S) ribosomal subunit; RPS0B has a paralog, RPS0A, that arose from the whole genome duplication; required for maturation of 18S rRNA along with Rps0Ap; deletion of either RPS0 gene reduces growth rate, deletion of both genes is lethal; homologous to human ribosomal protein SA and bacterial S2 |
0.125 | 3.42E-13 | YJL069C | UTP18 | het | Possible U3 snoRNP protein involved in maturation of pre-18S rRNA, based on computational analysis of large-scale protein-protein interaction data |
0.124 | 6.06E-13 | YLR129W | DIP2 | het | Nucleolar protein, specifically associated with the U3 snoRNA, part of the large ribonucleoprotein complex known as the small subunit (SSU) processome, required for 18S rRNA biogenesis, part of the active pre-rRNA processing complex |
0.123 | 1.02E-12 | YKL153W_d | YKL153W_d | het | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; transcription of both YLK153W and the overlapping essential gene GPM1 is reduced in the gcr1 null mutant |
0.121 | 2.38E-12 | YIR021W-A_p | YIR021W-A_p | hom | Putative protein of unknown function; identified by expression profiling and mass spectrometry |
0.111 | 1.01E-10 | YHR164C | DNA2 | het | Tripartite DNA replication factor; has single-stranded DNA-dependent ATPase, ATP-dependent nuclease, and helicase activities; required for Okazaki fragment processing; involved in DNA repair; cell-cycle dependent localization; forms nuclear foci upon DNA replication stress |
0.110 | 1.88E-10 | YOR085W | OST3 | hom | Gamma subunit of the oligosaccharyltransferase complex of the ER lumen, which catalyzes asparagine-linked glycosylation of newly synthesized proteins; Ost3p is important for N-glycosylation of a subset of proteins |
0.108 | 3.88E-10 | YBR236C | ABD1 | het | Methyltransferase, catalyzes the transfer of a methyl group from S-adenosylmethionine to the GpppN terminus of capped mRNA |
0.107 | 4.84E-10 | YDR023W | SES1 | het | Cytosolic seryl-tRNA synthetase, class II aminoacyl-tRNA synthetase that aminoacylates tRNA(Ser), displays tRNA-dependent amino acid recognition which enhances discrimination of the serine substrate, interacts with peroxin Pex21p |
0.106 | 7.35E-10 | YLR403W | SFP1 | hom | Regulates transcription of ribosomal protein and biogenesis genes; regulates response to nutrients and stress, G2/M transitions during mitotic cell cycle and DNA-damage response, and modulates cell size; regulated by TORC1 and Mrs6p; sequence of zinc finger, ChIP localization data, and protein-binding microarray (PBM) data, and computational analyses suggest it binds DNA directly at highly active RP genes and indirectly through Rap1p at others; can form the [ISP+] prion |
0.105 | 1.03E-9 | YOR159C | SME1 | het | Core Sm protein Sm E; part of heteroheptameric complex (with Smb1p, Smd1p, Smd2p, Smd3p, Smx3p, and Smx2p) that is part of the spliceosomal U1, U2, U4, and U5 snRNPs; homolog of human Sm E |
0.103 | 2.50E-9 | YEL019C | MMS21 | het | SUMO ligase and component of the SMC5-SMC6 complex; this complex plays a key role in the removal of X-shaped DNA structures that arise between sister chromatids during DNA replication and repair; mutants are sensitive to methyl methanesulfonate and show increased spontaneous mutation and mitotic recombination |
