CC -!- FUNCTION: Potassium channel subunit that does not form functional
CC channels by itself. Modulates KCNB1 and KCNB2 channel activity by
CC shifting the threshold for inactivation to more negative values and by
CC slowing the rate of inactivation. Can down-regulate the channel
CC activity of KCNB1, KCNB2, KCNC4 and KCND1, possibly by trapping them in
CC intracellular membranes (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Heteromultimer with KCNB1 and KCNB2. Interacts with KCNC4 and
CC KCND1 (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}. Note=Has to be associated with another potassium
CC channel subunit to get inserted in the plasma membrane. Remains
CC intracellular in the absence of KCNB2 (By similarity). {ECO:0000250}.
CC -!- DOMAIN: The segment S4 is probably the voltage-sensor and is
CC characterized by a series of positively charged amino acids at every
CC third position. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the potassium channel family. V (TC 1.A.1.2)
CC subfamily. Kv8.1/KCNV1 sub-subfamily. {ECO:0000305}.
