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. Assembled with KCNQ1/KVLQT1 is proposed to
CC form the slowly activating delayed rectifier cardiac potassium
CC (IKs) channel. The outward current reaches its steady state only
CC after 50 seconds. Assembled with KCNH2/HERG may modulate the
CC rapidly activating component of the delayed rectifying potassium
CC current in heart (IKr) (By similarity).
CC -!- SUBUNIT: Associates with KCNQ1/KVLQT1 and KCNH2/HERG (By
CC similarity).
CC -!- SUBCELLULAR LOCATION: Type I membrane protein.
CC -!- PTM: Phosphorylation inhibits the potassium current (By
CC similarity).
CC -!- SIMILARITY: Belongs to the potassium channel KCNE family.
