Potassium voltage-gated channel subfamily E member 4 (KCNE4)

Ancillary protein that assembles as a beta subunit with a voltage-gated potassium channel complex of pore-forming alpha subunits. Modulates the gating kinetics and enhances stability of the channel complex.

May associate with KCNQ1/KVLTQ1 and inhibit potassium current. .
