Function
function
High-affinity potassium transporter that could play a major role in the uptake of potassium from the rhizosphere. May act as a low-affinity potassium transporter under high potassium concentrations. Could also transport rubidium.
Miscellaneous
Low-affinity activity is strongly inhibited by barium or cesium.
