Dr. Fraser Moss and Dr. Walter Boron have had published in the Journal of Physiology their paper "Carbonic anhydrases enhance activity of endogenous Na-H exchangers and not the electrogenic Na/HCO3 cotransporter NBCe1-A, expressed in Xenopus oocytes" (https://doi.org/10.1113/JP280143) and the associated perspective article on their research "The devil is in the C-tail: a NBCe1-carbonic anhydrase bicarbonate transport metabolon?" (Jeppe Praetorius) (https://doi.org/10.1113/JP280143).
