Abstract excerpt

Hypertonic activation of NHE1, the ubiquitous Na+/H+ exchanger, plays a central role in cell volume regulation, yet little is known about the underlying mechanism. We probed the osmotic responsiveness of full-length and truncated constructs of NHE1 transfected into cells lacking endogenous antiport activity. The hypertonic stimulation of NHE1 was preserved after heterologous transfection of the full-length NHE1...
