Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Publication

Partial rescue of pos5 mutants by YEF1 and UTR1 genes in Saccharomyces cerevisiae.

Li YF, Shi F

Three NAD kinase homologs, encoded by UTR1, POS5 and YEF1 genes, are found in the yeast Saccharomyces cerevisiae and proven to be important sources of NADPH for the cell. Pos5p, existing in the mitochondrial matrix, is critical for higher temperature endurance and mitochondrial functions, such as glycerol usability and arginine biosynthesis. Through constructing the high-copy expression plasmids of YEF1 and ... [more]
