... showed that Slc26a6a and Slc26a6c are localized on the apical membrane of the P1 segment of the proximal tubule, while Slc26a6b is localized on the apical membrane and Slc26a1 on the basolateral membrane of the P2 segment. The current study revealed complex molecular mechanisms of SO 4 2– excretion...

...Walter F. Boron; Matthias A. Hediger; Emile L. Boulpaep; Michael F. Romero ABSTRACT The electrogenic Na + :HCO 3 − cotransporter (symporter) is the major transporter for HCO 3 − reabsorption across the basolateral membrane of the renal proximal tubule and also contributes significantly to Na...

...Heini Murer; Daniel Markovich; Jürg Biber ABSTRACT Homeostasis of inorganic phosphate (Pi) and sulphate (Si) is largely achieved by absorption in the mammalian small intestine and by reabsorption in the proximal tubule of the kidney. Under normal physiological conditions, the kidney appears to play...
