Model of apocalmodulin regulation of Kv7 PI(4,5)P2 efficacy. Illustration of the proposed equilibrium between three functional Kv7 channels pools. The PI(4,5)P2 efficacy depends upon the abundance of apoCaM and subunit composition. Pool 1 and pool 3 represent the currents observed after expression of a CaM sponge or overexpression of CaM1234, respectively.
