RT "SAUR inhibition of PP2C-D phosphatases activates plasma membrane H+-
RT ATPases to promote cell expansion in Arabidopsis.";
RL Plant Cell 26:2129-2142(2014).
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). Plays a role in the regulation of cell
CC expansion, root meristem patterning and auxin transport (By
CC similarity). {ECO:0000250|UniProtKB:Q9SA49,
CC ECO:0000269|PubMed:24858935}.
CC -!- SUBUNIT: Interacts with and inhibits PP2C-D subfamily of type 2C
CC phosphatases such as PP2C67/PP2C-D1. {ECO:0000269|PubMed:24858935}.
CC -!- INTERACTION:
CC Q9LTV3; O23160: MYB73; NbExp=3; IntAct=EBI-4458310, EBI-25506855;
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9SA49}.
CC -!- TISSUE SPECIFICITY: Highly expressed in the steles of roots and
CC hypocotyls. {ECO:0000269|PubMed:23759547}.
CC -!- SIMILARITY: Belongs to the ARG7 family. {ECO:0000305}.
