Background: Mutations in SLC4A11 result in corneal endothelial dystrophies; however, the transport characteristics of this membrane protein remain unclear. Results: SLC4A11 showed NH4Cl-dependent currents indicative of a NH3/H+ electrogenic co-transport mode. Conclusion: SLC4A11 is a novel NH3/H+ co-transporter, uncharacteristic of the SLC4 bicarbonate transporter family. Significance: SLC4A11 ammonia transport capacity should be considered along with other NH3 transporters/channels when examining tissue nitrogen homeostasis.
