CC   -!- FUNCTION: Provide a mechanistic link between auxin and plasma membrane
CC       H(+)-ATPases (PM H(+)-ATPases, e.g. AHA1 and AHA2), and triggers PM
CC       H(+)-ATPases activity by promoting phosphorylation of their C-terminal
CC       autoinhibitory domain as a result of PP2C-D subfamily of type 2C
CC       phosphatases inhibition, thus leading to the acidification of the
CC       apoplast and the facilitation of solutes and water uptake to drive cell
CC       expansion (By similarity). Triggers plant growth probably by promoting
CC       cell elongation (PubMed:29258424). Regulates branch angles and bending
CC       (PubMed:29258424). {ECO:0000250|UniProtKB:O65648,
CC       ECO:0000269|PubMed:29258424}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q9FJG1};
CC       Peripheral membrane protein {ECO:0000250|UniProtKB:Q9FJG1}.
CC   -!- TISSUE SPECIFICITY: Expressed in seedlings, leaves and flowers.
CC       {ECO:0000269|PubMed:29258424}.
CC   -!- DEVELOPMENTAL STAGE: In leaves, restricted to midveins and petioles
CC       (PubMed:29258424). In flowers, present in stamen and pistils styles and
CC       stigma (PubMed:29258424). {ECO:0000269|PubMed:29258424}.
CC   -!- INDUCTION: Slightly induced by abscisic acid.
CC       {ECO:0000269|PubMed:29258424}.
CC   -!- SIMILARITY: Belongs to the ARG7 family. {ECO:0000305}.
