A modular fragment of Arabidopsis cation exchanger 1 (CAX1) reveals structural constraints on assembly
{{output}}
Cation/H⁺ exchangers (CAXs) mediate vacuolar Ca2+ sequestration and are critical for maintaining cytosolic Ca2+ homeostasis in plants. Arabidopsis CAX1, a member of the Ca2+/Cation Antiporter (CaCA) superfamily, features a modular architecture comprising two ... ...
