Snf2p family member with ATP-dependent chromatin remodeling activity; has a role in silencing at the mating type locus, telomeres and centromeres; enriched at centromeres and is required for correct chromatin structure around centromeres, as well as at the boundary element of the silent HMR; recruited to DNA double-strand breaks (DSBs) where it promotes 5' strand resection of DSBs; potential Cdc28p substrate

Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.119 | 4.78E-12 | YJL118W | YJL118W | hom | Putative protein of unknown function; may interact with ribosomes, based on co-purification experiments; YJL18W is a non-essential gene; deletion enhances the toxicity of heterologously expressed human alpha-synuclein |
0.105 | 1.11E-9 | YMR048W | CSM3 | hom | Replication fork associated factor; required for stable replication fork pausing; component of the DNA replication checkpoint pathway; required for accurate chromosome segregation during meiosis; forms nuclear foci upon DNA replication stress |
0.103 | 2.54E-9 | YDR211W | GCD6 | het | Catalytic epsilon subunit of the translation initiation factor eIF2B; eIF2B is the guanine-nucleotide exchange factor for eIF2; activity subsequently regulated by phosphorylated eIF2; first identified as a negative regulator of GCN4 expression; forms cytoplasmic foci upon DNA replication stress |
0.100 | 6.88E-9 | YDL059C | RAD59 | hom | Protein involved DNA double-strand break repair; repairs breaks in DNA during vegetative growth via recombination and single-strand annealing; anneals complementary single-stranded DNA; forms nuclear foci upon DNA replication stress; required for loading of Rad52p to DSBs; paralog of Rad52p |
0.093 | 7.45E-8 | YDR121W | DPB4 | hom | Subunit of DNA pol epsilon and of ISW2 chromatin accessibility complex; involved in both chromosomal DNA replication and inheritance of telomeric silencing; stabilizes the interaction of Pol epsilon with primer-template DNA, positively affecting the processivity of the polymerase and exonuclease activities of Pol epsilon; interacts with extranucleosomal DNA and acts as anchor point for ISW2 complex that retains its position on DNA during nucleosome mobilization |
0.090 | 1.62E-7 | YPR061C | JID1 | hom | Probable Hsp40p co-chaperone, has a DnaJ-like domain and appears to be involved in ER-associated degradation of misfolded proteins containing a tightly folded cytoplasmic domain; inhibits replication of Brome mosaic virus in S. cerevisiae |
0.084 | 1.03E-6 | YOL104C | NDJ1 | hom | Meiosis-specific telomere protein, required for bouquet formation, effective homolog pairing, ordered cross-over distribution, sister chromatid cohesion at meiotic telomeres, chromosomal segregation and telomere-led rapid prophase movement |
0.084 | 1.06E-6 | YOR378W_p | YOR378W_p | hom | Putative paralog of ATR1, but not required for boron tolerance; member of the DHA2 family of drug:H+ antiporters; YOR378W is not an essential gene |
0.082 | 1.88E-6 | YDR436W | PPZ2 | hom | Serine/threonine protein phosphatase Z, isoform of Ppz1p; involved in regulation of potassium transport, which affects osmotic stability, cell cycle progression, and halotolerance |
0.079 | 5.04E-6 | YNL273W | TOF1 | hom | Subunit of a replication-pausing checkpoint complex (Tof1p-Mrc1p-Csm3p) that acts at the stalled replication fork to promote sister chromatid cohesion after DNA damage, facilitating gap repair of damaged DNA; interacts with the MCM helicase |
0.078 | 6.75E-6 | YMR187C_p | YMR187C_p | hom | Putative protein of unknown function; YMR187C is not an essential gene |
0.077 | 7.97E-6 | YGL051W | MST27 | hom | Putative integral membrane protein, involved in vesicle formation; forms complex with Mst28p; member of DUP240 gene family; binds COPI and COPII vesicles |
0.075 | 1.27E-5 | YOL003C | PFA4 | hom | Palmitoyltransferase with autoacylation activity, required for palmitoylation of amino acid permeases containing a C-terminal Phe-Trp-Cys site; required for modification of Chs3p; member of the DHHC family of putative palmitoyltransferases |
0.074 | 1.79E-5 | YBR224W_d | YBR224W_d | hom | Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data; partially overlaps the verified gene TDP1 |
0.073 | 2.57E-5 | YDR485C | VPS72 | hom | Htz1p-binding component of the SWR1 complex, which exchanges histone variant H2AZ (Htz1p) for chromatin-bound histone H2A; required for vacuolar protein sorting |
