Main conclusion The nuclear-localized CAX-interacting protein VvCXIP4 is exported to the cytosol after a Ca pulse, to activate the tonoplast-localized Ca/H exchanger VvCAX3. Abstract Vacuolar cation/H exchangers (CAXs) have long been recognized as 'housekeeping' components in cellular Ca and ...
Main conclusion The nuclear-localized CAX-interacting protein VvCXIP4 is exported to the cytosol after a Ca(2+)pulse, to activate the tonoplast-localized Ca2+/H(+)exchanger VvCAX3. Vacuolar cation/H(+)exchangers (CAXs) have long been recognized as 'housekeeping' components in cellular Ca(2+...
