Beta (RNA 5'-triphosphatase) subunit of the mRNA capping enzyme, a heterodimer (the other subunit is CEG1, a guanylyltransferase) involved in adding the 5' cap to mRNA; the mammalian enzyme is a single bifunctional polypeptide

Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.170 | 3.63E-23 | YDR206W | EBS1 | hom | Protein involved in inhibition of translation and nonsense-mediated decay; interacts with cap binding protein Cdc33p and with Nam7p; localizes to P-bodies upon glucose starvation; mRNA abundance regulated by mRNA decay factors |
0.130 | 4.91E-14 | YEL023C_p | YEL023C_p | hom | Putative protein of unknown function; expression is increased greatly during sporulation; YEL023C is not an essential gene |
0.125 | 3.13E-13 | YOR176W | HEM15 | het | Ferrochelatase, a mitochondrial inner membrane protein, catalyzes the insertion of ferrous iron into protoporphyrin IX, the eighth and final step in the heme biosynthetic pathway |
0.118 | 8.28E-12 | YMR119W-A_d | YMR119W-A_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.110 | 1.88E-10 | YDL220C | CDC13 | het | Single stranded DNA-binding protein found at TG1-3 telomere G-tails; regulates telomere replication through recruitment of specific sub-complexes, but the essential function is telomere capping; autophagy and proteasome are involved in Cdc13p degradation |
0.108 | 3.82E-10 | YOR180C | DCI1 | hom | Peroxisomal protein; identification as a delta(3,5)-delta(2,4)-dienoyl-CoA isomerase involved in fatty acid metabolism is disputed |
0.107 | 4.41E-10 | YGR226C_d | YGR226C_d | hom | Dubious open reading frame, unlikely to encode a protein; not conserved in closely related Saccharomyces species; overlaps significantly with a verified ORF, AMA1/YGR225W |
0.101 | 5.02E-9 | YLR319C | BUD6 | hom | Actin- and formin-interacting protein; stimulates actin cable nucleation by recruiting actin monomers to Bni1p; involved in polarized cell growth; isolated as bipolar budding mutant; potential Cdc28p substrate |
0.099 | 1.14E-8 | YJR019C | TES1 | hom | Peroxisomal acyl-CoA thioesterase likely to be involved in fatty acid oxidation rather than fatty acid synthesis; conserved protein also found in human peroxisomes; TES1 mRNA levels increase during growth on fatty acids |
0.098 | 1.39E-8 | YKL201C | MNN4 | hom | Putative positive regulator of mannosylphosphate transferase Mnn6p; involved in mannosylphosphorylation of N-linked oligosaccharides; expression increases in late-logarithmic and stationary growth phases; MNN4 has a paralog, YJR061W, that arose from the whole genome duplication |
0.097 | 2.12E-8 | YBR220C_p | YBR220C_p | hom | Putative protein of unknown function; YBR220C is not an essential gene |
0.094 | 4.27E-8 | YGR096W | TPC1 | hom | Mitochondrial membrane transporter that mediates uptake of the essential cofactor thiamine pyrophosphate (ThPP) into mitochondria; expression appears to be regulated by carbon source; member of the mitochondrial carrier family |
0.093 | 6.98E-8 | YLR366W_d | YLR366W_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the dubious ORF YLR364C-A |
0.092 | 9.45E-8 | YLR458W_d | YLR458W_d | het | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data; overlaps 5' end of essential NBP1 gene required for mitosis |
0.092 | 1.02E-7 | YMR080C | NAM7 | hom | ATP-dependent RNA helicase of the SFI superfamily; involved in nonsense mediated mRNA decay; required for efficient translation termination at nonsense codons and targeting of NMD substrates to P-bodies; involved in telomere maintenance; forms cytoplasmic foci upon DNA replication stress |
