Voltage-gated Na(+) channels in the brain are composed of a single pore-forming α subunit, one non-covalently linked β subunit (β1 or β3), and one disulfide-linked β subunit (β2 or β4). The final step in Na(+) channel biosynthesis in central neurons is concomitant α-β2 disulfide linkage and insertion into the plasma membrane. Consistent with this, Scn2b (encoding β2) null mice have reduced Na(+) channel cell surface expression in neurons, and action potential conduction is compromised. |

Nax is a sodium-concentration ([Na+])-sensitive Na channel with a gating threshold of ~150 mM for extracellular [Na+] ([Na+]o) in vitro. We previously reported that Nax was preferentially expressed in the glial cells of sensory circumventricular organs including the subfornical organ, and was involved in [Na+] sensing for the control of salt-intake behavior. |

Furthermore, we demonstrated that Nax bound to postsynaptic density protein 95 (PSD95) through its PSD95/Disc-large/ZO-1 (PDZ)-binding motif at the C-terminus in neurons. The interaction between Nax and PSD95 may be involved in promoting the surface expression of Nax channels because the depletion of endogenous PSD95 resulted in a decrease in Nax at the plasma membrane. These results indicated, for the first time, that Nax functions as a [Na+]-sensitive Na channel in neurons as well as in glial cells. |
