Human Na+/H+ exchanger protein and uses thereof

摘要

The invention is directed to two forms of isolated or purified human NHE2 polypeptide sequences, NHE2-LF and NHE2-SF, as well as the polynucleotide coding sequences that encode the human NHE2-LF and NHE2-SF polypeptides. Also featured are NHE2-LF- and NHE2-SF-related hosts, cell membrane preparations, vectors, and antibodies, as well as methods of using cells recombinantly expressing the human NHE2-LF or NHE2-SF, to identify agents that modulate human NHE activity.
