Correlation pval ORF Gene Zygosity Description
0.534 7.11E-247 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
0.505 1.93E-216 YJR142W_p YJR142W_p hom Putative protein of unknown function; GST fusion protein is a Dbf2p-Mob1p phosphorylation target in a proteome chip analysis; synthetic lethal with PH085 deletion; plays a role in restricting Ty1 transposition; nudix hydrolase family member
0.461 6.50E-176 YCL005W LDB16 hom Protein of unknown function; null mutants have decreased net negative cell surface charge; GFP-fusion protein expression is induced in response to the DNA-damaging agent MMS; native protein is detected in purified mitochondria
