Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.385 | 6.65E-119 | YNL257C | SIP3 | hom | Transcription cofactor; acts through interaction with DNA-bound Snf1p; C-terminal region has a putative leucine zipper motif; potential Cdc28p substrate; SIP3 has a paralog, YSP1, that arose from the whole genome duplication |
0.346 | 3.63E-95 | YJL005W | CYR1 | het | Adenylate cyclase, required for cAMP production and cAMP-dependent protein kinase signaling; the cAMP pathway controls a variety of cellular processes, including metabolism, cell cycle, stress response, stationary phase, and sporulation |
0.270 | 4.95E-57 | YIR012W | SQT1 | het | Protein involved in 60S ribosomal subunit assembly or modification; contains multiple WD repeats; interacts with Qsr1p in a two-hybrid assay; protein abundance increases in response to DNA replication stress |
0.236 | 1.12E-43 | YIL046W | MET30 | het | F-box protein containing five copies of the WD40 motif, controls cell cycle function, sulfur metabolism, and methionine biosynthesis as part of the ubiquitin ligase complex; interacts with and regulates Met4p, localizes within the nucleus |
0.233 | 1.63E-42 | YIL129C | TAO3 | het | Component of the RAM signaling network that is involved in regulation of Ace2p activity and cellular morphogenesis, interacts with protein kinase Cbk1p and also with Kic1p |
0.231 | 4.78E-42 | YDR414C | ERD1 | hom | Predicted membrane protein required for the retention of lumenal endoplasmic reticulum proteins; mutants secrete the endogenous ER protein, BiP (Kar2p) |
0.231 | 6.98E-42 | YDL002C | NHP10 | hom | Protein related to mammalian high mobility group proteins; preferentially binds DNA ends, protecting them from exonucleatic cleavage; likely component of the chromatin-remodeling complex INO80 complex; proposed to be involved in DNA repair |
0.217 | 3.49E-37 | YIR008C | PRI1 | het | Subunit of DNA primase, which is required for DNA synthesis and double-strand break repair |
0.213 | 1.31E-35 | YEL042W | GDA1 | hom | Guanosine diphosphatase located in the Golgi, involved in the transport of GDP-mannose into the Golgi lumen by converting GDP to GMP after mannose is transferred its substrate |
0.203 | 1.23E-32 | YMR102C_p | YMR102C_p | hom | Protein of unknown function; transcription is activated by paralogous transcription factors Yrm1p and Yrr1p along with genes involved in multidrug resistance; mutant shows increased resistance to azoles; YMR102C is not an essential gene |
0.200 | 1.02E-31 | YDR326C | YSP2 | hom | Protein involved in programmed cell death; mutant shows resistance to cell death induced by amiodarone or intracellular acidification; YSP2 has a paralog, YHR080C, that arose from the whole genome duplication |
0.196 | 1.56E-30 | YJR013W | GPI14 | het | Glycosylphosphatidylinositol-alpha 1,4 mannosyltransferase I, involved in GPI anchor biosynthesis, requires Pbn1p for function; homolog of mammalian PIG-M |
0.193 | 2.11E-29 | YDR435C | PPM1 | hom | Carboxyl methyltransferase, methylates the C terminus of the protein phosphatase 2A catalytic subunit (Pph21p or Pph22p), which is important for complex formation with regulatory subunits |
0.192 | 3.77E-29 | YNL027W | CRZ1 | hom | Transcription factor, activates transcription of stress response genes; nuclear localization is positively regulated by calcineurin-mediated dephosphorylation; rapidly localizes to the nucleus under blue light stress |
0.190 | 1.07E-28 | YDL210W | UGA4 | hom | Permease that serves as a gamma-aminobutyrate (GABA) transport protein involved in the utilization of GABA as a nitrogen source; catalyzes the transport of putrescine and delta-aminolevulinic acid (ALA); localized to the vacuolar membrane |
