Diphthamide synthetase; catalyzes the last amidation step of diphthamide biosynthesis using ammonium and ATP; evolutionarily conserved in eukaryotes; dph6 mutants exhibit diphthine accumulation and resistance to sordarin, which is indicative of defects in diphthamide formation on EF2; green fluorescent protein (GFP)-tagged protein localizes to the cytoplasm; DPH6/YLR143W is not an essential gene

Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.192 | 4.20E-29 | YPR029C | APL4 | hom | Gamma-adaptin, large subunit of the clathrin-associated protein (AP-1) complex; binds clathrin; involved in vesicle mediated transport |
0.170 | 4.18E-23 | YKL191W | DPH2 | hom | Protein required, along with Dph1p, Kti11p, Jjj3p, and Dph5p, for synthesis of diphthamide, which is a modified histidine residue of translation elongation factor 2 (Eft1p or Eft2p); may act in a complex with Dph1p and Kti11p |
0.160 | 1.18E-20 | YLR169W_d | YLR169W_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.142 | 1.66E-16 | YBR246W | RRT2 | hom | Protein required for last step of diphthamide biosynthesis; deletion leads to resistance to sordarin and accumulation of diphthine; WD40 domain-containing protein involved in endosomal recycling; forms a complex with Rtt10p that functions in the retromer-mediated pathway for recycling internalized cell-surface proteins; non-essential gene identified in a screen for mutants with increased levels of rDNA transcription |
0.138 | 1.13E-15 | YER120W | SCS2 | hom | Integral ER membrane protein, regulates phospholipid metabolism; one of 6 proteins (Ist2p, Scs2p, Scs22p, Tcb1p, Tcb2p, Tcb3p) that connect ER to the plasma membrane (PM) and regulate PI4P levels by controlling access of Sac1p phosphatase to its substrate PI4P in the PM; interacts with FFAT motif of Opi1p; involved in telomeric silencing; null shows inositol auxotrophy above 34 deg C; VAP homolog; SCS2 has a paralog, SCS22, that arose from the whole genome duplication |
0.138 | 1.21E-15 | YMR126C_p | DLT1_p | hom | Protein of unknown function, mutant sensitive to 6-azauracil (6AU) and mycophenolic acid (MPA) |
0.130 | 4.33E-14 | YBR245C | ISW1 | hom | ATPase subunit of imitation-switch (ISWI) class chromatin remodelers; ATPase; forms a complex with Ioc3p (Isw1a), and a complex with Ioc2p and Ioc4p (Isw1b); Isw1a and Isw1b have partially overlapping and distinct roles, Isw1a involved in repression of transcription initiation and Isw1b involved in regulation of transcription elongation; Isw1b recruited to open reading frames by H3K36 methylation and acts with Chd1p to prevent trans-histone exchange over coding regions |
0.128 | 1.04E-13 | YNL267W | PIK1 | het | Phosphatidylinositol 4-kinase; catalyzes first step in the biosynthesis of phosphatidylinositol-4,5-biphosphate; may control cytokinesis through the actin cytoskeleton |

0.127 | 1.55E-13 | YGR202C | PCT1 | hom | Cholinephosphate cytidylyltransferase; a rate-determining enzyme of the CDP-choline pathway for phosphatidylcholine synthesis, inhibited by Sec14p, activated upon lipid-binding; contains an element within the regulatory domain involved in both silencing and activation of enzymatic activity |
0.118 | 8.63E-12 | YDR159W | SAC3 | hom | Nuclear pore-associated protein; required for biogenesis of the small ribosomal subunit; component of TREX-2 complex (Sac3p-Thp1p-Sus1p-Cdc31p) involved in transcription elongation and mRNA export from the nucleus; involved in post-transcriptional tethering of active genes to the nuclear periphery and to non-nascent mRNP; similar to the human germinal center-associated nuclear protein (GANP) |
0.114 | 3.41E-11 | YOL001W | PHO80 | hom | Cyclin, interacts with cyclin-dependent kinase Pho85p; regulates the response to nutrient levels and environmental conditions, including the response to phosphate limitation and stress-dependent calcium signaling |
