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 (By similarity). Regulates branch angles and bending
CC (By similarity). {ECO:0000250|UniProtKB:O65648,
CC ECO:0000250|UniProtKB:Q9SI60}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q9FJG1};
CC Peripheral membrane protein {ECO:0000250|UniProtKB:Q9FJG1}.
CC -!- TISSUE SPECIFICITY: Expressed in trichomes (PubMed:29258424). Hardly
CC observed in leaves (PubMed:29258424). {ECO:0000269|PubMed:29258424}.
CC -!- DEVELOPMENTAL STAGE: Highly expressed in the trichomes of emerging
CC leaves (PubMed:29258424). Observed in flower stigma (PubMed:29258424).
CC {ECO:0000269|PubMed:29258424}.
CC -!- INDUCTION: Repressed by abscisic acid. {ECO:0000269|PubMed:29258424}.
CC -!- SIMILARITY: Belongs to the ARG7 family. {ECO:0000305}.
