When you exam the protein with <scene name='Sandbox7/No_helices/1'>no helices</scene> visible, it is clear that the protein binds ligand and has a four subunits structure similar to hemoglobin.

The potassium channel is an integral membrane protein consisting of four identical subunits. Because it is located in the membrane, its hydrophobic groups are located on the outside of the structure, where they interact with the lipids inside the membrane. The interior of the channel, meanwhile, is hydrophobic with polar groups to interact with potassium cations. are located on the outside of the alpha helices.
