Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.216 | 7.61E-37 | YER069W | ARG5,6 | hom | Acetylglutamate kinase and N-acetyl-gamma-glutamyl-phosphate reductase; N-acetyl-L-glutamate kinase (NAGK) catalyzes the 2nd and N-acetyl-gamma-glutamyl-phosphate reductase (NAGSA), the 3rd step in arginine biosynthesis; synthesized as a precursor which is processed in the mitochondrion to yield mature NAGK and NAGSA; enzymes form a metabolon complex with Arg2p; NAGK C-terminal domain stabilizes the enzymes, slows catalysis and is involved in feed-back inhibition by arginine |
0.172 | 8.55E-24 | YCR006C_d | YCR006C_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data |
0.166 | 4.16E-22 | YJR148W | BAT2 | hom | Cytosolic branched-chain amino acid (BCAA) aminotransferase, preferentially involved in BCAA catabolism; homolog of murine ECA39; highly expressed during stationary phase and repressed during logarithmic phase |
0.133 | 8.52E-15 | YMR191W | SPG5 | hom | Protein required for proteasome assembly during quiescence; binds to base of the proteasome regulartory particle; required for survival at high temperature during stationary phase; not required for growth on nonfermentable carbon sources |
0.125 | 3.68E-13 | YDL028C | MPS1 | het | Dual-specificity kinase; required for spindle pole body (SPB) duplication and spindle checkpoint function; substrates include SPB proteins Spc42p, Spc110p, and Spc98p, mitotic exit network protein Mob1p, kinetochore protein Cnn1p, and checkpoint protein Mad1p |
0.121 | 1.61E-12 | YGR122C-A_d | YGR122C-A_d | hom | Dubious open reading frame unlikely to encode a functional protein, similar to YLR334C and YOL106W |
0.120 | 3.88E-12 | YOL140W | ARG8 | hom | Acetylornithine aminotransferase, catalyzes the fourth step in the biosynthesis of the arginine precursor ornithine |
0.115 | 2.05E-11 | YHR193C | EGD2 | hom | Alpha subunit of the heteromeric nascent polypeptide-associated complex (NAC) involved in protein sorting and translocation, associated with cytoplasmic ribosomes |
0.108 | 3.13E-10 | YDR197W | CBS2 | hom | Mitochondrial translational activator of the COB mRNA; interacts with translating ribosomes, acts on the COB mRNA 5'-untranslated leader |
0.101 | 5.14E-9 | YLR454W_p | FMP27_p | hom | Putative protein of unknown function; the authentic, non-tagged protein is detected in highly purified mitochondria in high-throughput studies |
0.098 | 1.23E-8 | YLR230W_d | YLR230W_d | het | Dubious open reading frame unlikely to encode a functional protein; overlaps 5' end of essential CDC42 gene which encodes a small Rho-like GTPase essential for establishment and maintenance of cell polarity |
0.096 | 2.70E-8 | YDR179C | CSN9 | hom | Subunit of the Cop9 signalosome, which is required for deneddylation, or removal of the ubiquitin-like protein Rub1p from Cdc53p (cullin); involved in adaptation to pheromone signaling |
0.096 | 2.76E-8 | YOR353C | SOG2 | het | Key component of the RAM signaling network, required for proper cell morphogenesis and cell separation after mitosis |
0.094 | 5.37E-8 | YJL106W | IME2 | hom | Serine/threonine protein kinase involved in activation of meiosis, associates with Ime1p and mediates its stability, activates Ndt80p; IME2 expression is positively regulated by Ime1p |
0.092 | 9.40E-8 | YPL265W | DIP5 | hom | Dicarboxylic amino acid permease; mediates high-affinity and high-capacity transport of L-glutamate and L-aspartate; also a transporter for Gln, Asn, Ser, Ala, and Gly; relocalizes from plasma membrane to vacuole upon DNA replication stress |
