Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.141 | 2.42E-16 | YPL001W | HAT1 | hom | Catalytic subunit of the Hat1p-Hat2p histone acetyltransferase complex that uses the cofactor acetyl coenzyme A, to acetylate free nuclear and cytoplasmic histone H4; involved in telomeric silencing and DNA double-strand break repair |
0.121 | 2.15E-12 | YGL245W | GUS1 | het | Glutamyl-tRNA synthetase (GluRS); forms a complex with methionyl-tRNA synthetase (Mes1p) and Arc1p; complex formation increases the catalytic efficiency of both tRNA synthetases and ensures their correct localization to the cytoplasm; protein abundance increases in response to DNA replication stress |
0.119 | 4.61E-12 | YOL093W | TRM10 | hom | tRNA methyltransferase; methylates the N-1 position of guanosine in tRNAs; protein abundance increases in response to DNA replication stress |
0.114 | 3.11E-11 | YOR373W | NUD1 | het | Component of the spindle pole body outer plaque; acts through the mitotic exit network to specify asymmetric spindle pole body inheritance |
0.102 | 2.68E-9 | YHL002W | HSE1 | hom | Subunit of the endosomal Vps27p-Hse1p complex required for sorting of ubiquitinated membrane proteins into intralumenal vesicles prior to vacuolar degradation, as well as for recycling of Golgi proteins and formation of lumenal membranes |
0.097 | 2.04E-8 | YLR366W_d | YLR366W_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the dubious ORF YLR364C-A |
0.096 | 2.15E-8 | YDL235C | YPD1 | het | Phosphorelay intermediate protein, phosphorylated by the plasma membrane sensor Sln1p in response to osmotic stress and then in turn phosphorylates the response regulators Ssk1p in the cytosol and Skn7p in the nucleus |
0.094 | 5.76E-8 | YOR107W | RGS2 | hom | Negative regulator of glucose-induced cAMP signaling; directly activates the GTPase activity of the heterotrimeric G protein alpha subunit Gpa2p |
0.093 | 6.41E-8 | YPL081W | RPS9A | hom | Protein component of the small (40S) ribosomal subunit; homologous to mammalian ribosomal protein S9 and bacterial S4; RPS9A has a paralog, RPS9B, that arose from the whole genome duplication |
0.092 | 9.24E-8 | YKR011C | YKR011C | hom | Protein of unknown function; green fluorescent protein (GFP)-fusion protein localizes to the nucleus; protein abundance increases in response to DNA replication stress |
0.090 | 1.71E-7 | YOL028C | YAP7 | hom | Putative basic leucine zipper (bZIP) transcription factor; YAP7 has a paralog, YAP5, that arose from the whole genome duplication |
0.090 | 1.74E-7 | YGR110W | CLD1 | hom | Mitochondrial cardiolipin-specific phospholipase; functions upstream of Taz1p to generate monolyso-cardiolipin; transcription increases upon genotoxic stress; involved in restricting Ty1 transposition; has homology to mammalian CGI-58 |
0.089 | 2.09E-7 | YGR239C | PEX21 | hom | Peroxin required for peroxisomal matrix protein targeting; acts on proteins containing the PTS2 targeting sequence; interacts with Pex7p; partially redundant with Pex18p; relative distribution to cytoplasmic foci increases upon DNA replication stress |
0.087 | 3.94E-7 | YCL048W | SPS22 | hom | Protein of unknown function; SPS22 has a paralog, SPS2, that arose from the whole genome duplication; redundant with Sps2p for the organization of the beta-glucan layer of the spore wall |
0.087 | 4.26E-7 | YLR445W | GMC2 | hom | Protein involved in meiotic progression; mutants are delayed in meiotic nuclear division and are defective in synaptonemal complex assembly; transcription is regulated by Ume6p and induced in response to alpha factor |
