Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.623 | 0 | YDR080W | VPS41 | hom | Vacuolar membrane protein that is a subunit of the homotypic vacuole fusion and vacuole protein sorting (HOPS) complex; essential for membrane docking and fusion at the Golgi-to-endosome and endosome-to-vacuole stages of protein transport |
0.611 | 0 | YGL212W | VAM7 | hom | Vacuolar SNARE protein; functions with Vam3p in vacuolar protein trafficking; has an N-terminal PX domain (phosphoinositide-binding module) that binds PtdIns-3-P and mediates membrane binding; SNAP-25 homolog; protein abundance increases in response to DNA replication stress |
0.426 | 3.17E-148 | YML001W | YPT7 | hom | Rab family GTPase; GTP-binding protein of the rab family; required for homotypic fusion event in vacuole inheritance, for endosome-endosome fusion; interacts with the cargo selection/retromer complex for retrograde sorting; similar to mammalian Rab7 |
0.419 | 3.34E-143 | YGR261C | APL6 | hom | Beta3-like subunit of the yeast AP-3 complex; functions in transport of alkaline phosphatase to the vacuole via the alternate pathway; exists in both cytosolic and peripherally associated membrane-bound pools |
0.374 | 7.35E-112 | 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 |
0.351 | 6.39E-98 | 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 |
0.331 | 1.14E-86 | YBR288C | APM3 | hom | Mu3-like subunit of the clathrin associated protein complex (AP-3); functions in transport of alkaline phosphatase to the vacuole via the alternate pathway |
0.324 | 9.12E-83 | YJL024C | APS3 | hom | Small subunit of the clathrin-associated adaptor complex AP-3; involved in vacuolar protein sorting; related to the sigma subunit of the mammalian clathrin AP-3 complex; suppressor of loss of casein kinase 1 function; protein abundance increases in response to DNA replication stress |
0.313 | 3.87E-77 | 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 |
0.311 | 3.07E-76 | YPL195W | APL5 | hom | Delta adaptin-like subunit of the clathrin associated protein complex (AP-3); functions in transport of alkaline phosphatase to the vacuole via the alternate pathway, suppressor of loss of casein kinase 1 function |
0.289 | 1.40E-65 | YDL192W | ARF1 | hom | ADP-ribosylation factor; GTPase of the Ras superfamily involved in regulation of coated vesicle formation in intracellular trafficking within the Golgi; ARF1 has a paralog, ARF2, that arose from the whole genome duplication |
0.274 | 1.17E-58 | 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 |
0.269 | 1.57E-56 | 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 |
0.253 | 3.24E-50 | YJR033C | RAV1 | hom | Subunit of the RAVE complex (Rav1p, Rav2p, Skp1p), which promotes assembly of the V-ATPase holoenzyme; required for transport between the early and late endosome/PVC and for localization of TGN membrane proteins; potential Cdc28p substrate |
0.253 | 4.81E-50 | YGL012W | ERG4 | hom | C-24(28) sterol reductase, catalyzes the final step in ergosterol biosynthesis; mutants are viable, but lack ergosterol |
