Because it is located in the membrane, it consists of a number of cross-membrane <scene name='Sandbox7/Alpha_helices/1'>alpha helices</scene> (shown in blue)and its hydrophobic groups are mostly located on the outside of the structure, where they interact with the lipids inside the membrane. The interior of the channel, meanwhile, is hydrophilic with <scene name='Sandbox7/Aliphatic/1'>polar</scene> groups to interact with potassium cations, thus making the helices aliphatic. <scene name='Sandbox7/Hydrophobic_alpha-helices/2'>Hydrophobic residues</scene> (shown in green) are located on the outside of the alpha helices. | ||
