Function:
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.
Subunit:
Binds to 14-3-3 proteins. The binding is induced by phosphorylation of Thr-948. Binding to 14-3-3 proteins activates the H(+)-ATPase.
Subcellular Location:
Cell membrane; Multi-pass membrane proteinc(Probable).
Tissue Specificity:
Found predominantly in phloem cells of leaves, stems, roots and flowers.
Post-translational modifications:
Phosphorylation level varies significantly during early response to bacterial elicitor (e.g. fusicoccin FC).
Similarity:
Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIIA subfamily.
