UniProt Comments
Operates as a K+/H+ antiporter or Na+/H+ antiporter of the chloroplast envelope that functions in pH homeostasis and chloroplast development. Monovalent cation transporter with a preference for Cs+, K+ and Rb+ relative to Na+ or Li+. Required for pollen tube guidance, but not for normal pollen development. May also be involved in the development or function of the female gametophyte.
