NHE3/SLC9A3 Products

Description

Na+/H+ exchanger (NHE) family members are integral membrane proteins which play key role in catalyzing the extrusion of intracellular proton (H+) ions in exchange for extracellular sodium (Na+) ions for regulation of cellular pH as well as transepithelial ion/water transport. NHE3 or SLC9A3 is one of the best characterized NHEs that is a major proton extruding system driven by inward Na+ ion chemical gradient and is implicated in pH regulation to eliminate acids generated during metabolism or to tackle any potential adverse conditions in tissue microenvironment. NHE3 exists as a multi-pass membrane protein in cell membranes and is expressed most abundantly in colon and small intestine, followed by kidney and stomach, as well as in ventrolateral region of the medulla oblongata. In intestinal epithelial cells, it localizes to the ileal brush border and SGK1 mediated phosphorylation at Ser-661 has been shown to be associated with its enhanced cell membrane localization. NHE3 binds to SLC9A3R1 and SLC9A3R2, and interacts with CHP1, CHP2, SHANK2 PDZD3 and (interactions may decrease in response to elevated calcium ion levels). NHE3 is regulated by several hormones, neurotransmitters, and associated signaling systems such as cAMP, cGMP, and elevated intracellular calcium via mechanisms that are largely partially understood. NHE3 knock-out mice suffers from chronic diarrhea and altered salt as well as water homeostasis.
