Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.124 | 6.76E-13 | YDR530C | APA2 | hom | Diadenosine 5',5'''-P1,P4-tetraphosphate phosphorylase II; AP4A phosphorylase involved in catabolism of bis(5'-nucleosidyl) tetraphosphates; APA2 has a paralog, APA1, that arose from the whole genome duplication |
0.114 | 3.10E-11 | YIL084C | SDS3 | hom | Component of the Rpd3p/Sin3p deacetylase complex required for its structural integrity and catalytic activity, involved in transcriptional silencing and required for sporulation; cells defective in SDS3 display pleiotropic phenotypes |
0.101 | 4.44E-9 | 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 |
0.100 | 6.27E-9 | YML068W | ITT1 | hom | Protein that modulates the efficiency of translation termination, interacts with translation release factors eRF1 (Sup45p) and eRF3 (Sup35p) in vitro, contains a zinc finger domain characteristic of the TRIAD class of proteins |
0.094 | 4.43E-8 | YER034W | YER034W | hom | Protein of unknown function; non-essential gene; expression induced upon calcium shortage; protein abundance increases in response to DNA replication stress |
0.092 | 8.81E-8 | YLR136C | TIS11 | hom | mRNA-binding protein expressed during iron starvation; binds to a sequence element in the 3'-untranslated regions of specific mRNAs to mediate their degradation; involved in iron homeostasis; protein increases in abundance and relative distribution to the nucleus increases upon DNA replication stress |
0.088 | 2.99E-7 | 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 |
0.086 | 5.41E-7 | YOR140W | SFL1 | hom | Transcriptional repressor and activator; involved in repression of flocculation-related genes, and activation of stress responsive genes; negatively regulated by cAMP-dependent protein kinase A subunit Tpk2p |
0.081 | 2.94E-6 | 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 |
0.078 | 6.67E-6 | YLR050C_p | YLR050C_p | hom | Putative protein of unknown function; green fluorescent protein (GFP)-fusion protein localizes to the endoplasmic reticulum; YLR050C is not an essential gene |
0.077 | 8.01E-6 | YLL037W_d | YLL037W_d | het | Dubious open reading frame unlikely to encode a functional protein; overlaps 3' end of essential PRP19 gene encoding an RNA splicing factor |
0.076 | 9.41E-6 | YOR223W | YOR223W | hom | Subunit of the DSC ubiquitin ligase complex; protein of unknown function that localizes to the ER and vacuole lumen; overexpression affects endocytic protein trafficking; ortholog of fission yeast dsc3 |
0.075 | 1.47E-5 | YDR314C | RAD34 | hom | Protein involved in nucleotide excision repair (NER); homologous to RAD4 |
0.074 | 1.84E-5 | YJL141C | YAK1 | hom | Serine-threonine protein kinase; component of a glucose-sensing system that inhibits growth in response to glucose availability; upon nutrient deprivation Yak1p phosphorylates Pop2p to regulate mRNA deadenylation, the co-repressor Crf1p to inhibit transcription of ribosomal genes, and the stress-responsive transcription factors Hsf1p and Msn2p; nuclear localization negatively regulated by the Ras/PKA signaling pathway in the presence of glucose |
0.074 | 2.00E-5 | 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 |
