Sodium–hydrogen antiporter 1

The sodium-hydrogen antiporter 1 (NHE-1) also known as sodium/hydrogen exchanger 1 or SLC9A1 (SoLute Carrier family 9A1) is an isoform of sodium–hydrogen antiporter that in humans is encoded by the SLC9A1 gene.[5]

Function

edit

The Na+/H+ antiporter (SLC9A1) is a ubiquitous membrane-bound enzyme involved in volume- and pH-regulation of vertebrate cells. It is inhibited by the non-specific diuretic drug amiloride and activated by a variety of signals including growth factors, mitogens, neurotransmitters, tumor promoters, and others.[6]

Interactions

edit

Sodium–hydrogen antiporter 1 has been shown to interact with carbonic anhydrase II[7] and CHP.[8][9][10] It is also the target of the experimental drug rimeporide, which is being developed for the treatment of Duchenne muscular dystrophy.[11]
