CC -!- FUNCTION: Ancillary protein that assembles as a beta subunit with
CC a voltage-gated potassium channel complex of pore-forming alpha
CC subunits. Modulates the gating kinetics and enhances stability of
CC the channel complex. Associated with KCNC4/Kv3.4 is proposed to
CC form the subthreshold voltage-gated potassium channel in skeletal
CC muscle and to establish the resting membrane potential (RMP) in
CC muscle cells. Associated with KCNQ1/KCLQT1 may form the intestinal
CC cAMP-stimulated potassium channel involved in chloride secretion
CC (By similarity).
CC -!- SUBUNIT: Associates with KCNC4/Kv3.4. May associate with
CC KCNQ1/KVLQT1 (By similarity).
CC -!- SUBCELLULAR LOCATION: Type I membrane protein.
CC -!- SIMILARITY: Belongs to the potassium channel KCNE family.
