Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.170 | 4.81E-23 | YGL233W | SEC15 | het | Essential 113 kDa subunit of the exocyst complex; the exocyst mediates polarized targeting and tethering of post-Golgi secretory vesicles to active sites of exocytosis prior to SNARE-mediated fusion; interacts with and functions as a downstream effector of active, GTP-bound Sec4p, a Rab family GTPase |
0.166 | 2.96E-22 | YBR102C | EXO84 | het | Exocyst subunit with dual roles in exocytosis and spliceosome assembly; subunit of the the exocyst complex which mediates polarized targeting and tethering of post-Golgi secretory vesicles to active sites of exocytosis at the plasma membrane (PM) prior to SNARE-mediated fusion; required for exocyst assembly and targeting the complex to specific sites on the bud tip PM; associates the U1 snRNP; role in pre-mRNA splicing and prespliceosome formation; possible Cdc28 substrate |
0.154 | 2.20E-19 | YLR350W | ORM2 | hom | Evolutionarily conserved protein, similar to Orm1p; required for resistance to agents that induce unfolded protein response; Orm1p and Orm2p together control membrane biogenesis by coordinating lipid homeostasis with protein quality control; protein abundance increases in response to DNA replication stress |
0.150 | 2.98E-18 | YPR055W | SEC8 | het | Essential 121 kDa subunit of the exocyst complex; the exocyst mediates polarized targeting and tethering of post-Golgi secretory vesicles to active sites of exocytosis at the plasma membrane prior to SNARE-mediated fusion; involved in ER and Golgi inheritance in small buds; relocalizes away from bud neck upon DNA replication stress |
0.145 | 4.13E-17 | YJL207C | LAA1 | hom | AP-1 accessory protein; colocalizes with clathrin to the late-Golgi apparatus; involved in TGN-endosome transport; physically interacts with AP-1; similar to the mammalian p200; may interact with ribosomes; YJL207C is a non-essential gene |
0.138 | 9.90E-16 | YFL034W_p | YFL034W_p | hom | Putative integral membrane protein that interacts with Rpp0p, which is a component of the ribosomal stalk |
0.131 | 2.89E-14 | YMR218C | TRS130 | het | One of 10 subunits of the transport protein particle (TRAPP) complex of the cis-Golgi which mediates vesicle docking and fusion; involved in ER to Golgi membrane traffic; mutation activates transcription of OCH1; mutants are defective in cytoplasm-to-vacuole targeting (Cvt) pathway and starvation-induced autophagy |
0.130 | 4.66E-14 | 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 |
0.128 | 1.16E-13 | YIL068C | SEC6 | het | Essential 88kDa subunit of the exocyst complex; the exocyst mediates polarized targeting and tethering of post-Golgi secretory vesicles to active sites of exocytosis at the plasma membrane prior to SNARE-mediated fusion; anchors the assembled complex to sites of secretion; interacts with SM-like protein and SNARE regulator Sec1p and may recruit it to sites of secretion; interacts with Sec9p and inhibits formation of the t-SNARE complex between Sec9p and Sso1p |
0.127 | 1.56E-13 | YMR071C | TVP18 | hom | Integral membrane protein localized to late Golgi vesicles along with the v-SNARE Tlg2p; may interact with ribosomes, based on co-purification experiments |
0.124 | 5.55E-13 | YLR057W | MNL2 | hom | Putative mannosidase involved in ER-associated protein degradation; localizes to the endoplasmic reticulum; sequence similarity with seven-hairpin glycosidase (GH47) family members, such as Mns1p and Mnl1p, that hydrolyze 1,2-linked alpha-D-mannose residues; non-essential gene |
0.124 | 6.34E-13 | YJL144W | YJL144W | hom | Cytoplasmic hydrophilin essential in dessication-rehydration process; expression induced by osmotic stress, starvation and during stationary phase; protein abundance increases in response to DNA replication stress |
