Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.141 | 2.82E-16 | YOR220W | RCN2 | hom | Protein of unknown function; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm; phosphorylated in response to alpha factor; protein abundance increases in response to DNA replication stress |
0.139 | 7.80E-16 | YDL148C | NOP14 | het | Nucleolar protein, forms a complex with Noc4p that mediates maturation and nuclear export of 40S ribosomal subunits; also present in the small subunit processome complex, which is required for processing of pre-18S rRNA |
0.134 | 5.66E-15 | 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 |
0.134 | 6.23E-15 | YGR242W_d | YGR242W_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the verified ORF YAP1802/YGR241C |
0.130 | 4.34E-14 | YLR204W | QRI5 | hom | Mitochondrial inner membrane protein, required for accumulation of spliced COX1 mRNA; may have an additional role in translation of COX1 mRNA |
0.130 | 4.38E-14 | YDL037C | BSC1 | hom | Protein of unconfirmed function, similar to cell surface flocculin Flo11p; ORF exhibits genomic organization compatible with a translational readthrough-dependent mode of expression |
0.126 | 2.29E-13 | 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 |
0.125 | 4.13E-13 | YKL030W_d | YKL030W_d | hom | Dubious open reading frame, unlikely to encode a protein; not conserved in closely related Saccharomyces species; partially overlaps the verified gene MAE1 |
0.123 | 9.86E-13 | YDL027C_p | YDL027C_p | hom | Putative protein of unknown function; the authentic, non-tagged protein is detected in highly purified mitochondria in high-throughput studies; YDL027C is not an essential gene |
0.123 | 1.00E-12 | YGR049W | SCM4 | hom | Mitochondrial outer membrane protein of unknown function; predicted to have 4 transmembrane segments; import is mediated by Tom70p and Mim1p; interacts genetically with a cdc4 mutation |
0.116 | 1.38E-11 | YFL042C_p | YFL042C_p | hom | Putative protein of unknown function; YFL042C is not an essential gene |
0.113 | 4.37E-11 | YGL203C | KEX1 | hom | Protease involved in the processing of killer toxin and alpha factor precursor; cleaves Lys and Arg residues from the C-terminus of peptides and proteins |
0.110 | 1.42E-10 | YDR234W | LYS4 | hom | Homoaconitase, catalyzes the conversion of homocitrate to homoisocitrate, which is a step in the lysine biosynthesis pathway |
0.110 | 1.97E-10 | YER038W-A_d | YER038W-A_d | hom | Dubious open reading frame, unlikely to encode a protein; not conserved in closely related Saccharomyces species; 99% of ORF overlaps the verified gene HVG1; protein product detected in mitochondria |
0.109 | 2.47E-10 | YOL061W | PRS5 | hom | 5-phospho-ribosyl-1(alpha)-pyrophosphate synthetase; synthesizes PRPP, which is required for nucleotide, histidine, and tryptophan biosynthesis; one of five related enzymes, which are active as heteromultimeric complexes; forms cytoplasmic foci upon DNA replication stress |
