Protein Name:
ATPase 2, plasma membrane-type
|
UniprotKB/SwissProt ID: P19456 (P19456)
Gene Name:
AHA2
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: The plasma membrane H(+) ATPase of plants and fungi generates a proton gradient that drives the active transport of nutrients by H(+)-symport (PubMed:10748244, PubMed:12920605, PubMed:27013734). The resulting external acidification and/or internal alkinization may mediate growth responses (PubMed:10748244, PubMed:12920605). Involved in maintaining the membrane potential and delta-pH, together forming the plasma membrane protonmotive force (PMF) required for root and hypocotyl elongation and root tropism (PubMed:22214817, PubMed:24492258). Important for root growth and development during different nitrogen regimes (PubMed:25382626). Forms a functional cation-translocating unit with CNGC17 that is activated by PSKR1/BAK1 and possibly other BAK1/RLK complexes (PubMed:26071421). Promotes stomatal opening in response to blue light (PubMed:28358053, PubMed:31904040)
