Calcium-Activated Potassium (K_Ca) Channels

More Information »Calcium (Ca²⁺) -activated potassium channels (K_Ca) are a group of 6/7-TM ion channels that selectively transport K⁺ ions across biological membranes. They are broadly classified into three subtypes: SK, IK and BK channels (small, intermediate and big conductance).
