Research Abstract |
Na+/H+ exchangers (NHE. Or Nha) are found in the plasma or endosome membranes for the most cells of living organisms. Cytoplasmic pH is maintained at 7 while intracellular ensodome pH is set at weak acidic pH. NHEs are provided to regulate the cytoplasmic and endosome pH. However, their physiological function is still not clarified. In the present study, we focused on the physiological role of NHE localized at various endosomes and found a novel role in the intracellular protein trafficking.
