CC -!- FUNCTION: Potassium channel. {ECO:0000256|RuleBase:RU369015}.
CC -!- SUBUNIT: The potassium channel is composed of a homo- or
CC heterotetrameric complex of pore-forming subunits.
CC {ECO:0000256|RuleBase:RU369015}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|RuleBase:RU369015}; Multi-
CC pass membrane protein {ECO:0000256|RuleBase:RU369015}.
CC -!- DOMAIN: The segment S4 is probably the voltage-sensor and is
CC characterized by a series of positively charged amino acids. The pore-
CC forming region H5 is enclosed by the transmembrane segments S5 and S6
CC in the Shaker-type (1P/6TM) and contains the GYGD signature motif which
CC seems to be involved in potassium selectivity.
CC {ECO:0000256|RuleBase:RU369015}.
CC -!- SIMILARITY: Belongs to the potassium channel family. Plant (TC 1.A.1.4)
CC subfamily. {ECO:0000256|RuleBase:RU369015}.
