Saccharomyces cerevisiae YFR021w, YGR223c and YPL100w are paralogous ORFs of unknown function. Phenotypic analysis of overexpression, single-, double- and triple-ORF deletion strains under various growth conditions indicated mitochondria-related functions for all three ORFs. Two-hybrid screens of a yeast genomic library identified potentially interacting proteins for the three ORFs. Among these, the transcriptional activator Rtg3p interacted with both Yfr021wp and Ypl100wp and both ORF single...Expand abstract

Functional analysis of the Saccharomyces cerevisiae YFR021w/YGR223c/YPL100w ORF family suggests relations to mitochondrial/peroxisomal functions and amino acid signalling pathways.
