CC -!- FUNCTION: Voltage-gated potassium channel that mediates transmembrane
CC potassium transport in excitable membranes. Forms tetrameric potassium-
CC selective channels through which potassium ions pass in accordance with
CC their electrochemical gradient (By similarity). The channel alternates
CC between opened and closed conformations in response to the voltage
CC difference across the membrane (By similarity). Can form functional
CC homotetrameric channels and heterotetrameric channels that contain
CC variable proportions of KCNA1, KCNA2, KCNA4, KCNA6, and possibly other
CC family members as well; channel properties depend on the type of alpha
CC subunits that are part of the channel (By similarity). Channel
CC properties are modulated by cytoplasmic beta subunits that regulate the
CC subcellular location of the alpha subunits and promote rapid
CC inactivation (By similarity). Homotetrameric channels display rapid
CC activation and slow inactivation (By similarity).
CC {ECO:0000250|UniProtKB:P17658, ECO:0000250|UniProtKB:P17659}.
CC -!- SUBUNIT: Homotetramer and heterotetramer of potassium channel proteins
CC (Probable). Interacts with KCNAB1 and KCNAB2 (By similarity).
CC {ECO:0000250|UniProtKB:P17659, ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P17658};
CC Multi-pass membrane protein {ECO:0000305}.
CC -!- DOMAIN: The N-terminus may be important in determining the rate of
CC inactivation of the channel while the tail may play a role in
CC modulation of channel activity and/or targeting of the channel to
CC specific subcellular compartments.
CC -!- DOMAIN: The transmembrane segment S4 functions as a voltage-sensor and
CC is 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. A (Shaker) (TC
CC 1.A.1.2) subfamily. Kv1.6/KCNA6 sub-subfamily. {ECO:0000305}.
