Choline kinase; catalyzes the first step in phosphatidylcholine synthesis via the CDP-choline (Kennedy pathway); exhibits some ethanolamine kinase activity contributing to phosphatidylethanolamine synthesis via the CDP-ethanolamine pathway; CKI1 has a paralog, EKI1, that arose from the whole genome duplication

Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.303 | 3.09E-72 | YGL118C_d | YGL118C_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.303 | 4.67E-72 | YMR168C | CEP3 | het | Essential kinetochore protein, component of the CBF3 complex that binds the CDEIII region of the centromere; contains an N-terminal Zn2Cys6 type zinc finger domain, a C-terminal acidic domain, and a putative coiled coil dimerization domain |
0.300 | 1.00E-70 | YMR289W | ABZ2 | hom | Aminodeoxychorismate lyase (4-amino-4-deoxychorismate lyase), catalyzes the third step in para-aminobenzoic acid biosynthesis; involved in folic acid biosynthesis |
0.294 | 9.48E-68 | YMR166C_p | YMR166C_p | hom | Predicted transporter of the mitochondrial inner membrane; has similarity to human mitochondrial ATP-Mg/Pi carriers; YMR166C is not an essential gene |
0.287 | 1.13E-64 | YDL223C | HBT1 | hom | Substrate of the Hub1p ubiquitin-like protein that localizes to the shmoo tip (mating projection); mutants are defective for mating projection formation, thereby implicating Hbt1p in polarized cell morphogenesis |
0.267 | 9.24E-56 | YOR133W | EFT1 | hom | Elongation factor 2 (EF-2), also encoded by EFT2; catalyzes ribosomal translocation during protein synthesis; contains diphthamide, the unique posttranslationally modified histidine residue specifically ADP-ribosylated by diphtheria toxin; EFT1 has a paralog, EFT2, that arose from the whole genome duplication |
0.266 | 2.38E-55 | YHL039W | EFM1 | hom | Lysine methyltransferase involved in the monomethylation of eEF1A (Tef1p/Tef2p); SET-domain family member; predicted involvement in ribosome biogenesis; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm |
0.254 | 2.20E-50 | YEL032W | MCM3 | het | Protein involved in DNA replication; component of the Mcm2-7 hexameric complex that binds chromatin as a part of the pre-replicative complex |
0.248 | 2.96E-48 | YJL025W | RRN7 | het | Component of the core factor (CF) rDNA transcription factor complex; CF is required for transcription of 35S rRNA genes by RNA polymerase I and is composed of Rrn6p, Rrn7p, and Rrn11p |
0.211 | 3.22E-35 | YGR065C | VHT1 | het | High-affinity plasma membrane H+-biotin (vitamin H) symporter; mutation results in fatty acid auxotrophy; 12 transmembrane domain containing major facilitator subfamily member; mRNA levels negatively regulated by iron deprivation and biotin |
0.206 | 1.31E-33 | 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 |
0.206 | 1.91E-33 | YMR262W_p | YMR262W_p | hom | Protein of unknown function; interacts weakly with Knr4p; YMR262W is not an essential gene |
0.201 | 9.78E-32 | YGL041C_d | YGL041C_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.200 | 9.39E-32 | YNL124W | NAF1 | het | RNA-binding protein required for the assembly of box H/ACA snoRNPs and thus for pre-rRNA processing, forms a complex with Shq1p and interacts with H/ACA snoRNP components Nhp2p and Cbf5p; similar to Gar1p |
0.198 | 7.19E-31 | YGL077C | HNM1 | hom | Choline/ethanolamine transporter; involved in the uptake of nitrogen mustard and the uptake of glycine betaine during hypersaline stress; co-regulated with phospholipid biosynthetic genes and negatively regulated by choline and myo-inositol |
