Protein

Potassium voltage-gated channel subfamily E member 3

Gene

Kcne3

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

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. Associated with KCNC4/Kv3.4 is proposed to form the subthreshold voltage-gated potassium channel in skeletal muscle and to establish the resting membrane potential (RMP) in muscle cells. Associated with KCNQ1/KCLQT1 may form the intestinal cAMP-stimulated potassium channel involved in chloride secretion (By similarity).By similarity
