The NaK channel is like an [http://en.wikipedia.org/wiki/Ligand-gated_ion_channel '''intracellular gate''']. | The NaK channel is like an [http://en.wikipedia.org/wiki/Ligand-gated_ion_channel '''intracellular gate''']. | ||
The NaK channel have the same general architecture as the [[4hyo|K+ channels]]. In fact, the NaK channel has '''4 subunits''' which are '''symmetric''' with respect to the central axis of the pore. Each subunit is composed of '''3 alpha-helices'''. One of them is a short pore helix which is oblique to the channel axis. The others are the outer and the inner helices and they extend across the lipid membrane. | The NaK channel have the same general architecture as the [[4hyo|K+ channels]].

Hydrophobic amino-acids are around the structure so the helices can cross the membrane | ||
