Sedoheptulose bisphosphatase involved in riboneogenesis; dephosphorylates sedoheptulose 1,7-bisphosphate, which is converted via the nonoxidative pentose phosphate pathway to ribose-5-phosphate; facilitates the conversion of glycolytic intermediates to pentose phosphate units; also has fructose 1,6-bisphosphatase activity but this is probably not biologically relevant, since deletion does not affect FBP levels; GFP-fusion protein localizes to the cytoplasm and nucleus

Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.123 | 7.95E-13 | YNL149C | PGA2 | het | Essential protein required for maturation of Gas1p and Pho8p; involved in protein trafficking; GFP-fusion protein localizes to the ER and YFP-fusion protein to the nuclear envelope-ER network; null mutants have a cell separation defect |
0.115 | 2.56E-11 | YLR345W_p | YLR345W_p | hom | Similar to 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase enzymes responsible for the metabolism of fructoso-2,6-bisphosphate; mRNA expression is repressed by the Rfx1p-Tup1p-Ssn6p repressor complex; YLR345W is not an essential gene |
0.110 | 1.58E-10 | YEL023C_p | YEL023C_p | hom | Putative protein of unknown function; expression is increased greatly during sporulation; YEL023C is not an essential gene |
0.103 | 2.46E-9 | YML088W | UFO1 | hom | F-box receptor protein, subunit of the Skp1-Cdc53-F-box receptor (SCF) E3 ubiquitin ligase complex; binds to phosphorylated Ho endonuclease, allowing its ubiquitylation by SCF and subsequent degradation |
0.094 | 4.31E-8 | YKL146W | AVT3 | hom | Vacuolar transporter, exports large neutral amino acids from the vacuole; member of a family of seven S. cerevisiae genes (AVT1-7) related to vesicular GABA-glycine transporters |
0.093 | 7.12E-8 | YBR025C | OLA1 | hom | P-loop ATPase with similarity to human OLA1 and bacterial YchF; identified as specifically interacting with the proteasome; protein abundance increases in response to hydrogen peroxide and to DNA replication stress |
0.091 | 1.40E-7 | YDL029W | ARP2 | het | Essential component of the Arp2/3 complex, which is a highly conserved actin nucleation center required for the motility and integrity of actin patches; involved in endocytosis and membrane growth and polarity |
0.088 | 3.14E-7 | YIL136W | OM45 | hom | Mitochondrial outer membrane protein of unknown function; major constituent of the outer membrane, located on the outer (cytosolic) face; protein abundance increases in response to DNA replication stress |
0.087 | 4.81E-7 | YER067C-A_d | YER067C-A_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the uncharacterized ORF YER067W |
0.085 | 8.32E-7 | YDR051C | DET1 | hom | Acid phosphatase involved in the non-vesicular transport of sterols in both directions between the endoplasmic reticulum and plasma membrane; deletion confers sensitivity to nickel |
0.085 | 8.53E-7 | YLR398C | SKI2 | hom | Ski complex component and putative RNA helicase, mediates 3'-5' RNA degradation by the cytoplasmic exosome; null mutants have superkiller phenotype of increased viral dsRNAs and are synthetic lethal with mutations in 5'-3' mRNA decay |
0.084 | 9.81E-7 | YOR027W | STI1 | hom | Hsp90 cochaperone, interacts with the Ssa group of the cytosolic Hsp70 chaperones and activates Ssa1p ATPase activity; interacts with Hsp90 chaperones and inhibits their ATPase activity; homolog of mammalian Hop |
0.082 | 1.95E-6 | YDL048C | STP4 | hom | Protein containing a Kruppel-type zinc-finger domain; has similarity to Stp1p, Stp2p, and Stp3p; predicted to be a transcription factor; relative distribution to the nucleus increases upon DNA replication stress |
0.080 | 3.09E-6 | YBR089C-A | NHP6B | hom | High-mobility group (HMG) protein, binds to and remodels nucleosomes; involved in recruiting FACT and other chromatin remodelling complexes to the chromosomes; functionally redundant with Nhp6Ap; homologous to mammalian HMGB1 and HMGB2; NHP6B has a paralog, NHP6A, that arose from the whole genome duplication |
0.080 | 3.86E-6 | YNL150W_d | YNL150W_d | het | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; extensive overlap with PGA2/YNL149C, an uncharacterized gene with a proposed role in protein trafficking |
