Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.176 | 9.73E-25 | YDL220C | CDC13 | het | Single stranded DNA-binding protein found at TG1-3 telomere G-tails; regulates telomere replication through recruitment of specific sub-complexes, but the essential function is telomere capping; autophagy and proteasome are involved in Cdc13p degradation |
0.133 | 9.50E-15 | YLR262C-A | TMA7 | hom | Protein of unknown that associates with ribosomes; null mutant exhibits translation defects, altered polyribosome profiles, and resistance to the translation inhibitor anisomcyin; protein abundance increases in response to DNA replication stress |
0.117 | 8.98E-12 | YMR031C | EIS1 | hom | Component of the eisosome required for proper eisosome assembly; similarity to Ykl050cp and Uso1p; the authentic, non-tagged protein is detected in a phosphorylated state in highly purified mitochondria in high-throughput studies; protein increases in abundance and relocalizes from plasma membrane to cytoplasm upon DNA replication stress |
0.115 | 2.64E-11 | YDR021W | FAL1 | het | Nucleolar protein required for maturation of 18S rRNA, member of the eIF4A subfamily of DEAD-box ATP-dependent RNA helicases |
0.113 | 5.71E-11 | YOR335C | ALA1 | het | Cytoplasmic and mitochondrial alanyl-tRNA synthetase, required for protein synthesis; point mutation (cdc64-1 allele) causes cell cycle arrest at G1; lethality of null mutation is functionally complemented by human homolog |
0.112 | 7.44E-11 | YML054C | CYB2 | hom | Cytochrome b2 (L-lactate cytochrome-c oxidoreductase), component of the mitochondrial intermembrane space, required for lactate utilization; expression is repressed by glucose and anaerobic conditions |
0.111 | 1.53E-10 | YMR119W-A_d | YMR119W-A_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.104 | 1.58E-9 | YBR057C | MUM2 | hom | Cytoplasmic protein essential for meiotic DNA replication and sporulation; interacts with Orc2p, which is a component of the origin recognition complex |
0.103 | 2.29E-9 | YLR071C | RGR1 | het | Subunit of the RNA polymerase II mediator complex; associates with core polymerase subunits to form the RNA polymerase II holoenzyme; required for glucose repression, HO repression, RME1 repression and sporulation |
0.102 | 3.04E-9 | YDR236C | FMN1 | het | Riboflavin kinase, produces riboflavin monophosphate (FMN); FMN is a necessary cofactor for many enzymes; predominantly localizes to the microsomal fraction and also found in the mitochondrial inner membrane |
0.100 | 5.55E-9 | YDR206W | EBS1 | hom | Protein involved in inhibition of translation and nonsense-mediated decay; interacts with cap binding protein Cdc33p and with Nam7p; localizes to P-bodies upon glucose starvation; mRNA abundance regulated by mRNA decay factors |
0.099 | 1.08E-8 | 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 |
0.098 | 1.15E-8 | YDR117C | TMA64 | hom | Protein of unknown function that associates with ribosomes; has a putative RNA binding domain; in mammals the corresponding protein, eIF2D, has been shown to possess translation initiation factor activity |
0.097 | 1.98E-8 | YPR177C_d | YPR177C_d | het | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the 5' end of the essential PRP4 gene encoding a component of the U4/U6-U5 snRNP complex |
0.095 | 4.04E-8 | YDR143C | SAN1 | hom | Ubiquitin-protein ligase; involved in the proteasome-dependent degradation of aberrant nuclear proteins; targets substrates with regions of exposed hydrophobicity containing 5 or more contiguous hydrophobic residues; contains intrinsically disordered regions that contribute to substrate recognition |
