CAX1 beyond calcium transport: evidence for a transport-independent regulatory module in plants
Plant cation/H+ exchanger 1 (CAX1) is a vacuolar Ca2+/H+ antiporter that plays a central role in calcium homeostasis. The initial 36 residues of CAX1 make up the amino-terminal regulatory region (NRR), this defining feature mediates autoinhibition and serves as a target for phosphorylation and protein-protein interacti...
