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 (PubMed:24858935). Triggers plant growth probably by
CC promoting cell elongation (By similarity). Regulates branch angles and
CC bending (By similarity). Probably involved in light intensity mediated
CC root development (PubMed:31325959). {ECO:0000250|UniProtKB:Q9SI60,
CC ECO:0000269|PubMed:24858935, ECO:0000269|PubMed:31325959}.
CC -!- SUBUNIT: Interacts with and inhibits PP2C-D subfamily of type 2C
CC phosphatases such as PP2C67/PP2C-D1. {ECO:0000269|PubMed:24858935}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q9FJG1};
CC Peripheral membrane protein {ECO:0000250|UniProtKB:Q9FJG1}.
CC -!- TISSUE SPECIFICITY: Expressed in etiolated hypocotyls, petioles, leaves
CC and flowers. {ECO:0000269|PubMed:29258424}.
CC -!- DEVELOPMENTAL STAGE: Confined to the midveins of petioles and leaf
CC blades (PubMed:29258424). In flowers, only expressed in the filaments
CC and stigma papillae (PubMed:29258424). {ECO:0000269|PubMed:29258424}.
CC -!- INDUCTION: Induced by auxin in an ABP1-dependent manner
CC (PubMed:21223392, PubMed:29258424, PubMed:27999086). Triggered by
CC brassinosteroids, including brassinolide (BL) (PubMed:29258424,
CC PubMed:30649552). Accumulates in reduced red/far-red light ration
CC (R:FR) conditions mimicking shaded conditions (PubMed:29258424).
CC Repressed by abscisic acid (PubMed:29258424). Induced by light
CC (PubMed:31325959). {ECO:0000269|PubMed:21223392,
CC ECO:0000269|PubMed:27999086, ECO:0000269|PubMed:29258424,
CC ECO:0000269|PubMed:30649552, ECO:0000269|PubMed:31325959}.
CC -!- SIMILARITY: Belongs to the ARG7 family. {ECO:0000305}.
