Function
Plasma membrane Na(+)/H(+) antiporter. Mediates the electroneutral exchange of intracellular H(+) ions for extracellular Na(+) in 1:1 stoichiometry, thus regulating intracellular pH homeostasis, in particular in neural tissues (PubMed:9933641, PubMed:10692428, PubMed:19276089, PubMed:24936055). Acts as a negative regulator of dendritic spine growth (PubMed:21551074). Plays a role in postsynaptic remodeling and signaling (PubMed:24006492, PubMed:21551074). Can also contribute to organellar pH regulation, with consequences for receptor tyrosine kinase trafficking (PubMed:24936055).
