Mitochondrial type 2C protein phosphatase (PP2C) involved in regulation of pyruvate dehydrogenase activity by dephosphorylating the serine 133 of the Pda1p subunit; localizes to the intermembrane space and is imported via the presequence pathway and processed by the inner membrane protease (Imp1p-Imp2p); acts in concert with kinases Pkp1p and Pkp2p and phosphatase Ptc6p

Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.203 | 1.66E-32 | YKL202W_d | YKL202W_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.202 | 3.70E-32 | YBL086C_p | YBL086C_p | hom | Protein of unknown function; green fluorescent protein (GFP)-fusion protein localizes to the cell periphery |
0.142 | 1.27E-16 | YDR094W_d | YDR094W_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps verified ORF DNF2 |
0.131 | 2.90E-14 | YDR505C | PSP1 | hom | Asn and gln rich protein of unknown function; high-copy suppressor of POL1 (DNA polymerase alpha) and partial suppressor of CDC2 (polymerase delta) and CDC6 (pre-RC loading factor) mutations; overexpression results in growth inhibition; PSP1 has a paralog, YLR177W, that arose from the whole genome duplication |
0.130 | 3.44E-14 | YOR267C | HRK1 | hom | Protein kinase; implicated in activation of the plasma membrane H(+)-ATPase Pma1p in response to glucose metabolism; plays a role in ion homeostasis; protein abundance increases in response to DNA replication stress |
0.128 | 1.14E-13 | YAL037C-A_p | YAL037C-A_p | hom | Putative protein of unknown function |
0.114 | 3.59E-11 | YKR094C | RPL40B | hom | Ubiquitin-ribosomal 60S subunit protein L40B fusion protein; cleaved to yield ubiquitin and ribosomal protein L40B; ubiquitin may facilitate assembly of the ribosomal protein into ribosomes; homologous to mammalian ribosomal protein L40, no bacterial homolog; RPL40B has a paralog, RPL40A, that arose from the whole genome duplication |
0.114 | 4.22E-11 | YDR521W_d | YDR521W_d | hom | Dubious ORF that overlaps YDR520C; mutant increases expression of PIS1 and RPL3 in glycerol |
0.112 | 8.58E-11 | YGL166W | CUP2 | hom | Copper-binding transcription factor; activates transcription of the metallothionein genes CUP1-1 and CUP1-2 in response to elevated copper concentrations; CUP2 has a paralog, HAA1, that arose from the whole genome duplication |
0.111 | 1.22E-10 | YJR146W_p | YJR146W_p | hom | Protein of unknown function; expressed at both mRNA and protein levels; partially overlaps HMS2 |
0.109 | 2.67E-10 | YIL056W | VHR1 | hom | Transcriptional activator; required for the vitamin H-responsive element (VHRE) mediated induction of VHT1 (Vitamin H transporter) and BIO5 (biotin biosynthesis intermediate transporter) in response to low biotin concentrations; VHR1 has a paralog, VHR2, that arose from the whole genome duplication |
0.108 | 3.03E-10 | YOR152C_p | YOR152C_p | hom | Putative protein of unknown function; YOR152C is not an essential gene |
0.106 | 7.72E-10 | YDR089W | YDR089W | hom | Protein of unknown function; deletion confers resistance to nickel; contains an SPX domain, which is found in proteins involved in phosphate homeostasis; relocalizes from vacuole to cytoplasm upon DNA replication stress |
0.106 | 7.86E-10 | YGL137W | SEC27 | het | Essential beta'-coat protein of the COPI coatomer, involved in ER-to-Golgi and Golgi-to-ER transport; contains WD40 domains that mediate cargo selective interactions; 45% sequence identity to mammalian beta'-COP |
0.105 | 9.13E-10 | YER024W | YAT2 | hom | Carnitine acetyltransferase; has similarity to Yat1p, which is a carnitine acetyltransferase associated with the mitochondrial outer membrane |
