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). Functions as positive effectors of cell
CC expansion through modulation of auxin transport (By similarity).
CC Involved in thermo-responsiveness of plant architecture
CC (PubMed:31127632). Enhances plasma membrane H(+)-ATPase
CC (PubMed:31127632). Probably involved in light intensity mediated root
CC development (PubMed:31325959). {ECO:0000250|UniProtKB:O65648,
CC ECO:0000250|UniProtKB:Q9FJG1, ECO:0000269|PubMed:31127632,
CC ECO:0000269|PubMed:31325959}.
CC -!- SUBUNIT: Interacts with PP2C-D1. {ECO:0000269|PubMed:31127632}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q9FJG1};
CC Peripheral membrane protein {ECO:0000250|UniProtKB:Q9FJG1}.
CC -!- TISSUE SPECIFICITY: Higher expression in thermo-responsive cultivars
CC (e.g. cv. Alst-1, cv. Ang-0 and cv. Com-0) than in low thermo-
CC responsive cultivars (e.g. cv. Dja-1, cv. El-0 and cv. Kon).
CC {ECO:0000269|PubMed:31127632}.
CC -!- INDUCTION: PIF4-dependent regulation by temperature (PubMed:31127632).
CC In low thermo-responsive cultivars (e.g. Col-0), higher expression at
CC 28 degrees Celsius than at 22 degrees Celsius in petioles but not in
CC leaf blades (PubMed:31127632). In high thermo-responsive cultivars
CC (e.g. cv. Alst-1 and cv. Ang-0) higher expression at 28 degrees Celsius
CC than at 22 degrees Celsius in both petioles and leaf blades
CC (PubMed:31127632). Induced by light (PubMed:31325959).
CC {ECO:0000269|PubMed:31127632, ECO:0000269|PubMed:31325959}.
CC -!- DISRUPTION PHENOTYPE: Reduced rosette weight and area at 22 degrees
CC Celsius but not at 28 degrees Celsius. {ECO:0000269|PubMed:31127632}.
CC -!- MISCELLANEOUS: Exhibits a high natural sequence polymorphism between
CC cultivars, thus confering thermo-adaptation to environmental
CC conditions. {ECO:0000269|PubMed:31127632}.
CC -!- SIMILARITY: Belongs to the ARG7 family. {ECO:0000305}.
