CC   -!- FUNCTION: Probable inward-rectifying potassium channel. Assuming opened
CC       or closed conformations in response to the voltage difference across
CC       the membrane, the channel is activated by hyperpolarization (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
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 (By similarity).
CC       {ECO:0000250}.
CC   -!- DOMAIN: The KHA domain (rich in hydrophobic and acidic residues)
CC       present in the C-terminal part is likely to be important for
CC       tetramerization. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the potassium channel family. Plant (TC 1.A.1.4)
CC       subfamily. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAH93802.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
