Abstract
The Na+/H+ exchangers are important regulators of intracellular pH, cell volume, and cell proliferation. They exist in all cells with a cell-specific pattern of isoform expression. Na+/H+ exchangers are regulated by a variety of extracellular stimuli which activate G-protein-coupled receptors and receptor tyrosine. Heterotrimeric G proteins regulated distinct signaling pathways, some of which in turn regulate the activity of Na+/H+ exchangers. This review describes the recent findings concerning the molecular mechanisms of the G-protein-dependent regulation of Na+/H+ exchangers.
