The mammalian Na+/H+ exchanger isoform 1 (NHE1) is a ubiquitous membrane protein that exchanges one intracellular H+ for an extracellular Na+, thereby regulating cell pH and volume. NHE1 catalytic activity is mediated by a transmembrane (TM) domain with 12 transmembrane segments. We performed...
Structural and functional characterization of transmembrane segment IX of the NHE1 isoform of the na(+)/H(+) exchangerDownload
The Na+/H+ exchanger isoform 1 (NHE1) is an integral membrane protein that regulates intracellular pH by removing one intracellular H+ in exchange for one extracellular Na+. It has a large N-terminal membrane domain of 12 transmembrane segments and an intracellular C-terminal regulatory domain....
