Sodium/hydrogen exchanger 9B2

UniProtKB accession:  A0A6P3HVI0

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Electroneutral Na(+) Li(+)/H(+) antiporter that extrudes Na(+) or Li(+) in exchange for external protons across the membrane (PubMed:35173351). Uses the proton gradient/membrane potential to extrude sodium (By similarity). Contributes to the regulation of intracellular pH and sodium homeostasis (By similarity). Also able to mediate Na(+)/Li(+) antiporter activity in kidney (By similarity). May play a physiological role in renal tubular function and blood pressure homeostasis (By similarity). Plays an important role for insulin secretion and clathrin-mediated endocytosis in beta-cells. Involved in sperm motility and fertility. It is controversial whether SLC9B2 plays a role in osteoclast differentiation or not (By similarity).
