Sodium–hydrogen antiporter


Sodium–hydrogen antiporter

The sodium–hydrogen antiporter or sodium–hydrogen exchanger is a membrane protein found in many cells, and especially in those of the nephron of the kidney. It is primarily responsible for maintaining the balance of sodium.[1]

Isoforms

There are several isoforms of the antiporter:
