CC   -!- SUBUNIT: Homotetramer; which constitutes the calcium-activated
CC       potassium channel (By similarity).
CC   -!- SUBCELLULAR LOCATION: Integral membrane protein (By similarity).
CC   -!- DOMAIN: The S4 segment, which is characterized by a series of
CC       positively charged amino acids at every third position, is part of
CC       the voltage-sensor (By similarity).
CC   -!- DOMAIN: The pore-forming domain (also referred as P region) is
CC       imbedded into the membrane, and forms the selectivity filter of
CC       the pore. It contains the signature sequence of potassium channels
CC       that displays selectivity to potassium (By similarity).
