Potassium channel molecule. Computer model showing the secondary structure of a KcsA potassium ion (K+) channel molecule from Streptomyces lividans bacteria. Ion channels are membrane-spanning proteins that form a pathway for the movement of inorganic ions (purple sphere,centre) across cell membranes. K+ channels have many functions including regulating the secretion of hormones,generating electrical nerve impulses,and controlling the pace of the heart | |
