Potassium channels represent the most complex class of voltage-gated ion channels from both functional and structural standpoints. Four sequence-related potassium channel genes, shaker, shaw, shab, and shal, have been identified in Drosophila, and each has been shown to have human homolog(s). KCNA10 encodes a member of the potassium channel, voltage-gated, shaker-related subfamily. This member contains six membrane-spanning domains with a shaker-type repeat in the fourth segment. It is specifically regulated by cGMP and postulated to mediate the effects of substances that increase intracellular cGMP. |
