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.
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]

Additional Notes
- A synthetic genetic array (SGA) screen was used to identify genes that caused an increase in calcium or zinc sensitivity in a vma21QQ voa1::Hyg-R double mutant. VOA1 is genetically linked to the VMA21 locus. The voa1::Hyg-R allele enhances the V-ATPase deficiency of a vma21QQ mutant which has a dysfunctional ER retrieval motif.
