Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.270 | 4.46E-57 | YLR330W | CHS5 | hom | Component of the exomer complex, which also contains Csh6p, Bch1p, Bch2p, and Bud7p and is involved in export of selected proteins, such as chitin synthase Chs3p, from the Golgi to the plasma membrane |
0.254 | 2.00E-50 | YBL061C | SKT5 | hom | Activator of Chs3p (chitin synthase III) during vegetative growth; recruits Chs3p to the bud neck via interaction with Bni4p; SKT5 has a paralog, SHC1, that arose from the whole genome duplication |
0.237 | 3.16E-44 | YDR348C | PAL1 | hom | Protein of unknown function thought to be involved in endocytosis; Pal1p physically interacts with Ede1p and is found at endocytic sites at the cell periphery during the early stages of endocytosis; green fluorescent protein (GFP)-fusion protein also localizes to the bud neck; potential Cdc28p substrate; similar to the S. pombe Pal1 protein; relocalizes from bud neck to cytoplasm upon DNA replication stress |
0.236 | 1.39E-43 | YDR162C | NBP2 | hom | Protein involved in the HOG (high osmolarity glycerol) pathway; negatively regulates Hog1p by recruitment of phosphatase Ptc1p the Pbs2p-Hog1p complex; interacts with Bck1p and down regulates the cell wall integrity pathway; found in the nucleus and cytoplasm, contains an SH3 domain and a Ptc1p binding domain (PBM) |
0.234 | 5.44E-43 | YNL267W | PIK1 | het | Phosphatidylinositol 4-kinase; catalyzes first step in the biosynthesis of phosphatidylinositol-4,5-biphosphate; may control cytokinesis through the actin cytoskeleton |
0.223 | 5.69E-39 | 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 |
0.216 | 1.04E-36 | YNL079C | TPM1 | hom | Major isoform of tropomyosin; binds to and stabilizes actin cables and filaments, which direct polarized cell growth and the distribution of several organelles; acetylated by the NatB complex and acetylated form binds actin most efficiently; TPM1 has a paralog, TPM2, that arose from the whole genome duplication |
0.216 | 1.19E-36 | YOL003C | PFA4 | hom | Palmitoyltransferase with autoacylation activity, required for palmitoylation of amino acid permeases containing a C-terminal Phe-Trp-Cys site; required for modification of Chs3p; member of the DHHC family of putative palmitoyltransferases |
0.210 | 7.10E-35 | YKL145W | RPT1 | het | One of six ATPases of the 19S regulatory particle of the 26S proteasome involved in the degradation of ubiquitinated substrates; required for optimal CDC20 transcription; interacts with Rpn12p and Ubr1p; mutant has aneuploidy tolerance |
0.208 | 2.73E-34 | YLL043W | FPS1 | hom | Plasma membrane channel, member of major intrinsic protein (MIP) family; involved in efflux of glycerol and in uptake of acetic acid and the trivalent metalloids arsenite and antimonite; phosphorylated by Hog1p MAPK under acetate stress |
0.207 | 6.94E-34 | YJL099W | CHS6 | hom | Member of the ChAPs (Chs5p-Arf1p-binding proteins) family; part of the exomer complex that mediates export of specific cargo proteins, including Chs3p, from the Golgi to the plasma membrane; CHS6 has a paralog, BCH2, that arose from the whole genome duplication |
0.200 | 1.39E-31 | YDR351W | SBE2 | hom | Protein involved in the transport of cell wall components from the Golgi to the cell surface; required for bud growth |
0.198 | 4.92E-31 | YJR102C | VPS25 | hom | Component of the ESCRT-II complex, which is involved in ubiquitin-dependent sorting of proteins into the endosome |
0.198 | 6.11E-31 | YJL081C | ARP4 | het | Nuclear actin-related protein involved in chromatin remodeling, component of chromatin-remodeling enzyme complexes |
0.198 | 7.14E-31 | YGL035C | MIG1 | hom | Transcription factor involved in glucose repression; sequence specific DNA binding protein containing two Cys2His2 zinc finger motifs; regulated by the SNF1 kinase and the GLC7 phosphatase; regulates filamentous growth along with Mig2p in response to glucose depletion |
