NCBI Protein Information
H[+]-ATPase 1
NCBI Summary
Encodes a plasma membrane proton ATPase. Mutants have a reduced ability to close their stomata in response to drought and are affected in stomatal but not seed responsiveness to ABA.

UniProt Comments
The plasma membrane H+ ATPase of plants and fungi generates a proton gradient that drives the active transport of nutrients by H+-symport. The resulting external acidification and/or internal alkinization may mediate growth responses. Forms a functional cation-translocating unit with CNGC17 that is activated by PSKR1/BAK1 and possibly other BAK1/RLK complexes (PubMed:26071421).
