Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.583 | 3.73E-305 | 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 |
0.496 | 1.10E-207 | YDR323C | PEP7 | hom | Multivalent adaptor protein that facilitates vesicle-mediated vacuolar protein sorting by ensuring high-fidelity vesicle docking and fusion, which are essential for targeting of vesicles to the endosome; required for vacuole inheritance |
0.492 | 7.18E-204 | YLR020C | YEH2 | hom | Steryl ester hydrolase, catalyzes steryl ester hydrolysis at the plasma membrane; involved in sterol metabolism |
0.465 | 1.19E-179 | YOR089C | VPS21 | hom | Rab family GTPase; required for endocytic transport and for sorting of vacuolar hydrolases; localized in endocytic intermediates; detected in mitochondria; geranylgeranylation required for membrane association; mammalian Rab5 homolog; protein abundance increases in response to DNA replication stress; VPS21 has a paralog, YPT53, that arose from the whole genome duplication |
0.461 | 5.29E-176 | 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 |
0.432 | 1.00E-152 | YOR036W | PEP12 | hom | Target membrane receptor (t-SNARE) for vesicular intermediates traveling between the Golgi apparatus and the vacuole; controls entry of biosynthetic, endocytic, and retrograde traffic into the prevacuolar compartment; syntaxin |
0.415 | 8.44E-140 | 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 |
0.412 | 7.46E-138 | YDR495C | VPS3 | hom | Component of CORVET tethering complex; cytoplasmic protein required for the sorting and processing of soluble vacuolar proteins, acidification of the vacuolar lumen, and assembly of the vacuolar H+-ATPase |
0.401 | 5.97E-130 | YDR491C_d | YDR491C_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.393 | 4.11E-124 | 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 |
0.376 | 6.40E-113 | YAL002W | VPS8 | hom | Membrane-binding component of the CORVET complex; involved in endosomal vesicle tethering and fusion in the endosome to vacuole protein targeting pathway; interacts with Vps21p; contains RING finger motif |
0.375 | 4.12E-112 | YNL267W | PIK1 | het | Phosphatidylinositol 4-kinase; catalyzes first step in the biosynthesis of phosphatidylinositol-4,5-biphosphate; may control cytokinesis through the actin cytoskeleton |
0.370 | 3.24E-109 | YPR092W_d | YPR092W_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.354 | 7.16E-100 | 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 |
0.344 | 5.59E-94 | YAR042W | SWH1 | hom | Protein similar to mammalian oxysterol-binding protein; contains ankyrin repeats; localizes to the Golgi and the nucleus-vacuole junction |
