Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.477 | 3.84E-190 | YDR047W | HEM12 | het | Uroporphyrinogen decarboxylase, catalyzes the fifth step in the heme biosynthetic pathway; localizes to both the cytoplasm and nucleus; a hem12 mutant has phenotypes similar to patients with porphyria cutanea tarda |
0.441 | 7.54E-160 | YBR192W | RIM2 | het | Mitochondrial pyrimidine nucleotide transporter; imports pyrimidine nucleoside triphosphates and exports pyrimidine nucleoside monophosphates; member of the mitochondrial carrier family |
0.395 | 2.11E-125 | YGL040C | HEM2 | het | Aminolevulinate dehydratase, a homo-octameric enzyme, catalyzes the conversion of 5-aminolevulinate to porphobilinogen, the second step in heme biosynthesis; enzymatic activity is zinc-dependent; localizes to the cytoplasm and nucleus |
0.357 | 3.26E-101 | YKL195W | MIA40 | het | Oxidoreductase that mediates mitochondrial intermembrane space import; substrates include small proteins containing twin cysteine motifs; acts in concert with Erv1p, which oxidizes the cysteine residues of Mia40p to comprise a disulfide relay system that catalyzes import; also mediates folding of Atp23p |
0.345 | 1.07E-94 | YER021W | RPN3 | het | Essential, non-ATPase regulatory subunit of the 26S proteasome lid, similar to the p58 subunit of the human 26S proteasome; temperature-sensitive alleles cause metaphase arrest, suggesting a role for the proteasome in cell cycle control |
0.297 | 1.88E-69 | YDR232W | HEM1 | het | 5-aminolevulinate synthase, catalyzes the first step in the heme biosynthetic pathway; an N-terminal signal sequence is required for localization to the mitochondrial matrix; expression is regulated by Hap2p-Hap3p |
0.294 | 6.78E-68 | YDL147W | RPN5 | het | Subunit of the COP9 signalosome (CSN) and non-ATPase regulatory subunit of the 26S proteasome lid, similar to mammalian p55 subunit and to another S. cerevisiae regulatory subunit, Rpn7p; Rpn5p is an essential protein |
0.286 | 5.06E-64 | YEL034W | HYP2 | het | Translation elongation factor eIF-5A; may function in translation initiation; structural homolog of bacterial EF-P; undergoes an essential hypusination modification; HYP2 has a paralog, ANB1, that arose from the whole genome duplication |
0.275 | 4.83E-59 | YDL196W_d | YDL196W_d | het | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; open reading frame is located in promoter region of essential gene SEC31 |
0.272 | 7.13E-58 | YDR427W | RPN9 | het | Non-ATPase regulatory subunit of the 26S proteasome; has similarity to putative proteasomal subunits in other species; null mutant is temperature sensitive and exhibits cell cycle and proteasome assembly defects; protein abundance increases in response to DNA replication stress |
0.270 | 3.92E-57 | YKR008W | RSC4 | het | Component of the RSC chromatin remodeling complex; found in close proximity to nucleosomal DNA; displaced from the surface of nucleosomal DNA after chromatin remodeling; acetylated (K25) by Gcn5p, altering replication stress tolerance; contains tandem bromodomains that recognize histone H3 acetylated on K14 (H3K14ac) by Gcn5p |
0.263 | 2.69E-54 | YBL105C | PKC1 | het | Protein serine/threonine kinase essential for cell wall remodeling during growth; localized to sites of polarized growth and the mother-daughter bud neck; homolog of the alpha, beta, and gamma isoforms of mammalian protein kinase C (PKC) |
0.257 | 1.03E-51 | YMR203W | TOM40 | het | Component of the TOM (translocase of outer membrane) complex responsible for recognition and initial import steps for all mitochondrially directed proteins; constitutes the core element of the protein conducting pore |
0.248 | 2.26E-48 | YIL126W | STH1 | het | ATPase component of the RSC chromatin remodeling complex; required for expression of early meiotic genes; essential helicase-related protein homologous to Snf2p |
0.245 | 8.46E-47 | YDR303C | RSC3 | het | Component of the RSC chromatin remodeling complex; essential gene required for maintenance of proper ploidy and regulation of ribosomal protein genes and the cell wall/stress response; highly similar to Rsc30p |
