CC -!- FUNCTION: Pore-forming (alpha) subunit of voltage-gated potassium
CC channel. Elicits a slowly activating, outward rectifying current (By
CC similarity). Channel properties may be modulated by cAMP and subunit
CC assembly (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: The potassium channel is probably composed of a homo- or
CC heterotetrameric complex of pore-forming alpha subunits that can
CC associate with modulating beta subunits.
CC -!- SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.
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.
CC -!- SIMILARITY: Belongs to the potassium channel family. H (Eag) (TC
CC 1.A.1.20) subfamily. Kv12.1/KCNH8 sub-subfamily. {ECO:0000305}.
CC -!- CAUTION: There seems to be a problem in the assembly of the Mouse
CC genome in the region covered by contigs AC125051 and AC131674.
CC {ECO:0000305}.
