CLS11, H(+)-transporting V1 sector ATPase subunit H, L000002465, YPR036W
Subunit H of the V1 peripheral membrane domain of V-ATPase; part of the electrogenic proton pump found throughout the endomembrane system; serves as an activator or a structural stabilizer of the V-ATPase; the V1 peripheral membrane domain of the vacuolar H+-ATPase (V-ATPase) has eight subunits

Synthetic Haploinsufficiency

A genetic interaction is inferred when mutations or deletions in separate genes, at least one of which is hemizygous, cause a minimal phenotype alone but result in lethality when combined in the same cell under a given condition.

The V-ATPase works in parallel with the HOG pathway to adapt yeast cells to osmotic stress.

Li SC, Diakov TT, Rizzo JM, Kane PM

Hyperosmotic stress activates an array of cellular detoxification mechanisms, including the high osmolarity glycerol (HOG) pathway. We report that vacuolar H(+)-ATPase (V-ATPase) activity helps provide osmotic tolerance in yeast. V-ATPase subunit genes exhibit complex haploinsufficiency interactions with HOG pathway components. vma mutants lacking V-ATPase function are sensitive to high concentrations of salt and exhibit Hog1p activation even at low salt ...
