Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.299 | 2.80E-70 | YOR067C | ALG8 | hom | Glucosyl transferase, involved in N-linked glycosylation; adds glucose to the dolichol-linked oligosaccharide precursor prior to transfer to protein during lipid-linked oligosaccharide biosynthesis; similar to Alg6p |
0.290 | 7.43E-66 | YDL096C_d | OPI6_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps verified gene PMT1/YDL095W; YDL096C is not essential |
0.262 | 8.54E-54 | YOR085W | OST3 | hom | Gamma subunit of the oligosaccharyltransferase complex of the ER lumen, which catalyzes asparagine-linked glycosylation of newly synthesized proteins; Ost3p is important for N-glycosylation of a subset of proteins |
0.224 | 2.02E-39 | YKL096C-B_p | YKL096C-B_p | hom | Putative protein of unknown function; identified by gene-trapping, microarray-based expression analysis, and genome-wide homology searching |
0.223 | 6.25E-39 | YBL082C | ALG3 | hom | Dolichol-P-Man dependent alpha(1-3) mannosyltransferase, involved in the synthesis of dolichol-linked oligosaccharide donor for N-linked glycosylation of proteins |
0.208 | 4.32E-34 | YGR166W | TRS65 | hom | Subunit of TRAPPII, a multimeric guanine nucleotide-exchange factor for Ypt1p; involved in intra-Golgi traffic and the retrograde pathway from the endosome to Golgi; role in cell wall beta-glucan biosynthesis and the stress response |
0.206 | 1.61E-33 | YML115C | VAN1 | hom | Component of the mannan polymerase I, which contains Van1p and Mnn9p and is involved in the first steps of mannan synthesis; mutants are vanadate-resistant |
0.201 | 4.67E-32 | YNL322C | KRE1 | hom | Cell wall glycoprotein involved in beta-glucan assembly; serves as a K1 killer toxin membrane receptor |
0.201 | 5.28E-32 | YNL219C | ALG9 | hom | Mannosyltransferase, involved in N-linked glycosylation; catalyzes both the transfer of seventh mannose residue on B-arm and ninth mannose residue on the C-arm from Dol-P-Man to lipid-linked oligosaccharides; mutation of the human ortholog causes type 1 congenital disorders of glycosylation |
0.201 | 9.05E-32 | YAL058W | CNE1 | hom | Calnexin; integral membrane ER chaperone involved in folding and quality control of glycoproteins; chaperone activity is inhibited by Mpd1p, with which Cne1p interacts; 24% identical to mammalian calnexin; Ca+ binding not yet shown in yeast |
0.194 | 7.77E-30 | YJR075W | HOC1 | hom | Alpha-1,6-mannosyltransferase involved in cell wall mannan biosynthesis; subunit of a Golgi-localized complex that also contains Anp1p, Mnn9p, Mnn11p, and Mnn10p; identified as a suppressor of a cell lysis sensitive pkc1-371 allele |
0.174 | 2.75E-24 | YBR229C | ROT2 | hom | Glucosidase II catalytic subunit required for normal cell wall synthesis; mutations in rot2 suppress tor2 mutations, and are synthetically lethal with rot1 mutations |
0.171 | 1.59E-23 | YBL083C_d | YBL083C_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; overlaps verified ORF ALG3 |
0.171 | 2.43E-23 | YAL053W | FLC2 | hom | Putative FAD transporter; required for uptake of FAD into endoplasmic reticulum; involved in cell wall maintenance; FLC2 has a paralog, YOR365C, that arose from the whole genome duplication |
0.167 | 1.85E-22 | YDL095W | PMT1 | hom | Protein O-mannosyltransferase of the ER membrane; transfers mannose from dolichyl phosphate-D-mannose to protein serine and threonine residues; 1 of 7 related proteins involved in O-glycosylation which is essential for cell wall rigidity; involved in ER quality control; amino terminus faces cytoplasm, carboxyl terminus faces ER lumen |
