Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

A Genome-wide Enhancer Screen Implicates Sphingolipid Composition in Vacuolar ATPase Function in Saccharomyces cerevisiae.

Finnigan GC, Ryan M, Stevens TH

The function of the vacuolar H(+)-ATPase enzyme complex is to acidify organelles; this process is critical for a variety of cellular processes and has implications in human disease. There are five accessory proteins that assist in assembly of the membrane portion of the complex, the V(0) domain. To identify additional elements that affect V-ATPase assembly, trafficking, or enzyme activity, we ... [more]
