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

Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.381 | 4.27E-116 | YMR036C | MIH1 | hom | Protein tyrosine phosphatase involved in cell cycle control; regulates the phosphorylation state of Cdc28p; homolog of S. pombe cdc25 |
0.366 | 1.36E-106 | YBL085W | BOI1 | hom | Protein implicated in polar growth; functionally redundant with Boi2p; interacts with bud-emergence protein Bem1p; contains an SH3 (src homology 3) domain and a PH (pleckstrin homology) domain; relocalizes from bud neck to cytoplasm upon DNA replication stress; BOI1 has a paralog, BOI2, that arose from the whole genome duplication |
0.350 | 6.54E-97 | YLL032C | YLL032C | hom | Protein of unknown function that may interact with ribosomes, based on co-purification experiments; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm; YLL032C is not an essential gene |
0.335 | 1.28E-88 | YMR121C | RPL15B | hom | Ribosomal 60S subunit protein L15B; binds to 5.8 S rRNA; homologous to mammalian ribosomal protein L15, no bacterial homolog; RPL15B has a paralog, RPL15A, that arose from the whole genome duplication; relocalizes from nucleus to nucleolus upon DNA replication stress |
0.309 | 4.62E-75 | 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 |
0.300 | 7.68E-71 | YBR020W | GAL1 | hom | Galactokinase; phosphorylates alpha-D-galactose to alpha-D-galactose-1-phosphate in the first step of galactose catabolism; expression regulated by Gal4p; GAL1 has a paralog, GAL3, that arose from the whole genome duplication |
0.300 | 9.63E-71 | YMR124W_p | YMR124W_p | hom | Protein of unknown function; GFP-fusion protein localizes to the cell periphery, cytoplasm, bud, and bud neck; interacts with Crm1p in two-hybrid assay; YMR124W is not an essential gene; predicted to have a role in organelle organization |
0.300 | 9.51E-71 | YGL033W | HOP2 | hom | Meiosis-specific protein that localizes to chromosomes, preventing synapsis between nonhomologous chromosomes and ensuring synapsis between homologs; complexes with Mnd1p to promote homolog pairing and meiotic double-strand break repair |
0.289 | 1.48E-65 | YOR091W | TMA46 | hom | Protein of unknown function that associates with translating ribosomes; interacts with GTPase Rbg1p |
0.266 | 2.76E-55 | YML119W_p | YML119W_p | hom | Putative protein of unknown function; YML119W is not an essential gene; potential Cdc28p substrate |
0.262 | 7.51E-54 | YBR134W_d | YBR134W_d | hom | Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data |
0.253 | 5.50E-50 | YLR102C | APC9 | hom | Subunit of the Anaphase-Promoting Complex/Cyclosome (APC/C), which is a ubiquitin-protein ligase required for degradation of anaphase inhibitors, including mitotic cyclins, during the metaphase/anaphase transition |
0.252 | 9.42E-50 | 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 |
0.246 | 3.29E-47 | YGR211W | ZPR1 | het | Essential protein with two zinc fingers; present in the nucleus of growing cells but relocates to the cytoplasm in starved cells via a process mediated by Cpr1p; binds to translation elongation factor eEF-1 (Tef1p); relative distribution to the nucleus increases upon DNA replication stress |
