Function | Ancillary protein that functions as a regulatory subunit of the voltage-gated potassium (Kv) channel complex composed of pore-forming and potassium-conducting alpha subunits and of regulatory beta subunits. KCNE4 beta subunit modulates the gating kinetics and enhances stability of the channel complex. Associates with KCNQ1/KVLTQ1 alpha subunit to inhibit potassium currents. Isoform 2: May inhibit KCNQ4-mediated potassium currents. |
