Correlation | pval | ORF | Gene | Zygosity | Description |
---|---|---|---|---|---|
0.200 | 1.60E-31 | YDR318W | MCM21 | hom | Component of the kinetochore sub-complex COMA; COMA (Ctf19p, Okp1p, Mcm21p, Ame1p) bridges kinetochore subunits in contact with centromeric DNA with subunits bound to microtubules during kinetochore assembly; involved in minichromosome maintenance; orthologous to human centromere constitutive-associated network (CCAN) subunit CENP-O and fission yeast mal2 |
0.174 | 2.67E-24 | YMR036C | MIH1 | hom | Protein tyrosine phosphatase involved in cell cycle control; regulates the phosphorylation state of Cdc28p; homolog of S. pombe cdc25 |
0.148 | 6.65E-18 | 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 |
0.147 | 9.50E-18 | YOR195W | SLK19 | hom | Kinetochore-associated protein required for normal segregation of chromosomes in meiosis and mitosis; component of the FEAR regulatory network, which promotes Cdc14p release from the nucleolus during anaphase; potential Cdc28p substrate |
0.141 | 2.66E-16 | 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 |
0.140 | 3.41E-16 | 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 |
0.136 | 2.64E-15 | YEL063C | CAN1 | hom | Plasma membrane arginine permease; requires phosphatidyl ethanolamine (PE) for localization, exclusively associated with lipid rafts; mutation confers canavanine resistance; CAN1 has a paralog, ALP1, that arose from the whole genome duplication |
0.128 | 1.09E-13 | 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 |
0.121 | 1.77E-12 | YML119W_p | YML119W_p | hom | Putative protein of unknown function; YML119W is not an essential gene; potential Cdc28p substrate |
0.118 | 6.31E-12 | YBL034C | STU1 | het | Component of the mitotic spindle that binds to interpolar microtubules via its association with beta-tubulin (Tub2p); required for interpolar microtubules to provide an outward force on the spindle poles |
0.117 | 8.50E-12 | YDR117C | TMA64 | hom | Protein of unknown function that associates with ribosomes; has a putative RNA binding domain; in mammals the corresponding protein, eIF2D, has been shown to possess translation initiation factor activity |
0.117 | 1.07E-11 | 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 |
0.116 | 1.58E-11 | YOR083W | WHI5 | hom | Repressor of G1 transcription that binds to SCB binding factor (SBF) at SCB target promoters in early G1; phosphorylation of Whi5p by the CDK, Cln3p/Cdc28p relieves repression and promoter binding by Whi5; periodically expressed in G1 |
