Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.481 | 4.06E-194 | YPR091C | NVJ2 | hom | Lipid-binding ER protein, enriched at nucleus-vacuolar junctions (NVJ); may be involved in sterol metabolism or signaling at the NVJ; contains a synaptotagmin-like-mitochondrial- lipid binding protein (SMP) domain; binds phosphatidylinositols and other lipids in a large-scale study; may interact with ribosomes, based on co-purification experiments |
0.377 | 4.54E-114 | YHR108W | GGA2 | hom | Protein that interacts with and regulates Arf1p and Arf2p in a GTP-dependent manner to facilitate traffic through the late Golgi; binds phosphatidylinositol 4-phosphate, which plays a role in TGN localization; has homology to gamma-adaptin |
0.376 | 7.69E-113 | YNL267W | PIK1 | het | Phosphatidylinositol 4-kinase; catalyzes first step in the biosynthesis of phosphatidylinositol-4,5-biphosphate; may control cytokinesis through the actin cytoskeleton |
0.366 | 6.31E-107 | YLR020C | YEH2 | hom | Steryl ester hydrolase, catalyzes steryl ester hydrolysis at the plasma membrane; involved in sterol metabolism |
0.359 | 2.05E-102 | YNL183C | NPR1 | hom | Protein kinase that stabilizes several plasma membrane amino acid transporters by antagonizing their ubiquitin-mediated degradation; phosphorylates Aly2p; negatively regulates Ldb19p-mediated endocytosis through phosphorylation of Ldb19p, which prevents its association with the plasma membrane; Npr1p activity is negatively regulated via phosphorylation by the TOR complex |
0.350 | 4.21E-97 | YOR357C | SNX3 | hom | Sorting nexin required to maintain late-Golgi resident enzymes in their proper location by recycling molecules from the prevacuolar compartment; contains a PX domain and sequence similarity to human Snx3p |
0.344 | 5.59E-94 | YML097C | VPS9 | hom | A guanine nucleotide exchange factor involved in vesicle-mediated vacuolar protein transport; specifically stimulates the intrinsic guanine nucleotide exchange activity of Vps21p/Rab5: similar to mammalian ras inhibitors; binds ubiquitin |
0.341 | 3.13E-92 | YJL052W | TDH1 | hom | Glyceraldehyde-3-phosphate dehydrogenase, isozyme 1; involved in glycolysis and gluconeogenesis; tetramer that catalyzes the reaction of glyceraldehyde-3-phosphate to 1,3 bis-phosphoglycerate; detected in the cytoplasm and cell wall; protein abundance increases in response to DNA replication stress |
0.340 | 1.50E-91 | YDR084C | TVP23 | hom | Integral membrane protein localized to late Golgi vesicles along with the v-SNARE Tlg2p; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm in a punctate pattern |
0.337 | 7.45E-90 | YDR492W | IZH1 | hom | Membrane protein involved in zinc ion homeostasis, member of the four-protein IZH family; transcription is regulated directly by Zap1p, expression induced by zinc deficiency and fatty acids; deletion increases sensitivity to elevated zinc |
0.336 | 6.04E-89 | YPR092W_d | YPR092W_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.333 | 6.28E-88 | YJL154C | VPS35 | hom | Endosomal subunit of membrane-associated retromer complex required for retrograde transport; receptor that recognizes retrieval signals on cargo proteins, forms subcomplex with Vps26p and Vps29p that selects cargo proteins for retrieval; interacts with Ypt7p |
0.332 | 5.19E-87 | YML037C_p | YML037C_p | hom | Putative protein of unknown function with some characteristics of a transcriptional activator; may be a target of Dbf2p-Mob1p kinase; GFP-fusion protein co-localizes with clathrin-coated vesicles; YML037C is not an essential gene |
0.326 | 6.51E-84 | YER120W | SCS2 | hom | Integral ER membrane protein, regulates phospholipid metabolism; one of 6 proteins (Ist2p, Scs2p, Scs22p, Tcb1p, Tcb2p, Tcb3p) that connect ER to the plasma membrane (PM) and regulate PI4P levels by controlling access of Sac1p phosphatase to its substrate PI4P in the PM; interacts with FFAT motif of Opi1p; involved in telomeric silencing; null shows inositol auxotrophy above 34 deg C; VAP homolog; SCS2 has a paralog, SCS22, that arose from the whole genome duplication |
0.320 | 8.31E-81 | YBR246W | RRT2 | hom | Protein required for last step of diphthamide biosynthesis; deletion leads to resistance to sordarin and accumulation of diphthine; WD40 domain-containing protein involved in endosomal recycling; forms a complex with Rtt10p that functions in the retromer-mediated pathway for recycling internalized cell-surface proteins; non-essential gene identified in a screen for mutants with increased levels of rDNA transcription |
