Scientific Background: Sodium-hydrogen exchanger 3 (NHE3; Slc9a3) is an epithelial transport protein that carries out 1:1 exchange of Na+ and H+ across the plasma membrane. It is apically located in the proximal tubule of the kidney, the thick ascending limb of the kidney, and in small intestine (1). NHE3 is phosphorylated and regulated by multiple kinases including PKA, SGK1 and CK2. It can be phosphorylated by calyculin A, and dephosphorylated by PP1 catalytic subunit in vitro (2).
