Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.100 | 7.38E-9 | YEL065W | SIT1 | hom | Ferrioxamine B transporter, member of the ARN family of transporters that specifically recognize siderophore-iron chelates; transcription is induced during iron deprivation and diauxic shift; potentially phosphorylated by Cdc28p |
0.087 | 5.09E-7 | YMR309C | NIP1 | het | eIF3c subunit of the eukaryotic translation initiation factor 3 (eIF3), involved in the assembly of preinitiation complex and start codon selection |
0.082 | 1.89E-6 | YOL031C | SIL1 | hom | Nucleotide exchange factor for the endoplasmic reticulum (ER) lumenal Hsp70 chaperone Kar2p, required for protein translocation into the ER; homolog of Yarrowia lipolytica SLS1; GrpE-like protein |
0.082 | 1.89E-6 | YHR203C | RPS4B | hom | Protein component of the small (40S) ribosomal subunit; homologous to mammalian ribosomal protein S4, no bacterial homolog; RPS4B has a paralog, RPS4A, that arose from the whole genome duplication |
0.078 | 6.85E-6 | YPL009C | TAE2 | hom | Protein of unknown function, involved in protein translation; may interact with ribosomes, based on co-purification experiments; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm |
0.076 | 9.51E-6 | YNL299W | TRF5 | hom | Non-canonical poly(A) polymerase, involved in nuclear RNA degradation as a component of the TRAMP complex; catalyzes polyadenylation of hypomodified tRNAs, and snoRNA and rRNA precursors; overlapping but non-redundant functions with Pap2p |
0.075 | 1.38E-5 | YGR271W | SLH1 | hom | Putative RNA helicase related to Ski2p, involved in translation inhibition of non-poly(A) mRNAs; required for repressing propagation of dsRNA viruses |
0.074 | 1.61E-5 | YJL031C | BET4 | het | Alpha subunit of Type II geranylgeranyltransferase required for vesicular transport between the endoplasmic reticulum and the Golgi; provides a membrane attachment moiety to Rab-like proteins Ypt1p and Sec4p |
0.074 | 1.65E-5 | YOR296W_p | YOR296W_p | hom | Putative protein of unknown function; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm; expressed during copper starvation; YOR296W is not an essential gene |
0.074 | 2.02E-5 | YNL312W | RFA2 | het | Subunit of heterotrimeric Replication Protein A (RPA); RPA is a highly conserved single-stranded DNA binding protein involved in DNA replication, repair, and recombination; protein abundance increases in response to DNA replication stress |
0.073 | 2.52E-5 | YDR010C_d | YDR010C_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data |
0.071 | 4.21E-5 | YJR082C | EAF6 | hom | Subunit of the NuA4 acetyltransferase complex that acetylates histone H4 and NuA3 acetyltransferase complex that acetylates histone H3 |
0.070 | 5.24E-5 | YDL205C | HEM3 | het | Porphobilinogen deaminase, catalyzes the conversion of 4-porphobilinogen to hydroxymethylbilane, the third step in heme biosynthesis; localizes to the cytoplasm and nucleus; expression is regulated by Hap2p-Hap3p, but not by levels of heme |
0.070 | 5.42E-5 | YEL067C_p | YEL067C_p | hom | Putative protein of unknown function; the authentic, non-tagged protein is detected in highly purified mitochondria in high-throughput studies |
0.070 | 5.44E-5 | YPR186C | PZF1 | het | Transcription factor IIIA (TFIIIA); essential DNA binding protein required for transcription of 5S rRNA by RNA polymerase III; not involved in transcription of other RNAP III genes; nine conserved zinc fingers; may also bind 5S rRNA |
