0.112 | 8.38E-11 | YLR004C | THI73 | hom | Putative plasma membrane permease proposed to be involved in carboxylic acid uptake and repressed by thiamine; substrate of Dbf2p/Mob1p kinase; transcription is altered if mitochondrial dysfunction occurs |
0.106 | 6.94E-10 | YGR127W_p | YGR127W_p | hom | Putative protein of unknown function; expression is regulated by Msn2p/Msn4p, indicating a possible role in stress response |
0.104 | 1.53E-9 | YMR277W | FCP1 | het | Carboxy-terminal domain (CTD) phosphatase, essential for dephosphorylation of the repeated C-terminal domain of the RNA polymerase II large subunit (Rpo21p) |
0.103 | 2.04E-9 | YML100W-A_p | YML100W-A_p | hom | Putative protein of unknown function; identified by gene-trapping, microarray-based expression analysis, and genome-wide homology searching |
0.099 | 9.72E-9 | YHL026C_p | YHL026C_p | hom | Putative protein of unknown function; transcriptionally regulated by Upc2p via an upstream sterol response element; YHL026C is not an essential gene; in 2005 the start site was moved 141 nt upstream (see Locus History) |
0.096 | 2.43E-8 | YFR012W-A_p | YFR012W-A_p | hom | Putative protein of unknown function; identified by homology |
