General description

Sodium/hydrogen exchanger 3 (UniProt: Q28362; also known as Na(+)/H(+) exchanger 3, NHE-3, Solute carrier family 9 member 3) is encoded by the SLC9A3 (also known as NHE3) gene in Didelphis virginiana (North American opossum). NHE-3 is a multi-pass membrane protein that is involved in pH regulation to eliminate acids generated by active metabolism or to counter adverse environmental conditions. NHE-3 is predominantly expressed in kidney and gut, where it is found on the apical membranes of polarized epithelial cells and plays a central role in transepithelial reabsorption of sodium ions and secretion of hydrogen ions. Renal NHE-3 is essential in maintaining blood pressure and steady-state plasma sodium levels when dietary sodium chloride intake is modified. In the intestine epithelial cells, it localizes to the ileal brush border. Dysfunction of NHE-3 in intestine is associated with a variety of diarrheal diseases. HNE-3 can be phosphorylated by SGK1 at Ser669 that increases its abundance at the cell membrane. (Ref.: D Souza, S et al. (1998). J. Biol. Chem. 273(4); 2035 2043; Fenton, RA et al (2017).
