CC -!- FUNCTION: Potassium channel subunit that does not form functional
CC channels by itself. Can form functional heterotetrameric channels with
CC KCNB1; modulates the delayed rectifier voltage-gated potassium channel
CC activation and deactivation rates of KCNB1.
CC {ECO:0000250|UniProtKB:D4AD53}.
CC -!- SUBUNIT: Heterotetramer with KCNB1. {ECO:0000250|UniProtKB:D4AD53}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:D4AD53};
CC Multi-pass membrane protein {ECO:0000250|UniProtKB:D4AD53}.
CC -!- DOMAIN: The transmembrane segment S4 functions as voltage-sensor and is
CC characterized by a series of positively charged amino acids at every
CC third position. Channel opening and closing is effected by a
CC conformation change that affects the position and orientation of the
CC voltage-sensor paddle formed by S3 and S4 within the membrane. A
CC transmembrane electric field that is positive inside would push the
CC positively charged S4 segment outwards, thereby opening the pore, while
CC a field that is negative inside would pull the S4 segment inwards and
CC close the pore. Changes in the position and orientation of S4 are then
CC transmitted to the activation gate formed by the inner helix bundle via
CC the S4-S5 linker region. {ECO:0000250|UniProtKB:P63142}.
CC -!- SIMILARITY: Belongs to the potassium channel family. G (TC 1.A.1.2)
CC subfamily. Kv6.1/KCNG1 sub-subfamily. {ECO:0000305}.
