CC   -!- FUNCTION: Highly selective inward-rectifying potassium channel that
CC       mediates potassium uptake by plant roots. Assuming opened or closed
CC       conformations in response to the voltage difference across the
CC       membrane, the channel is activated by hyperpolarization. May be a major
CC       salt-sensitive potassium channel in roots.
CC       {ECO:0000269|PubMed:15599592}.
CC   -!- SUBUNIT: The potassium channel is probably a homo- or heterotetrameric
CC       complex of pore-forming subunits. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Expressed in roots and coleoptile of young
CC       seedlings. {ECO:0000269|PubMed:15599592}.
CC   -!- INDUCTION: Down-regulated by salt stress.
CC       {ECO:0000269|PubMed:15599592}.
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=AK120308; Type=Frameshift; Evidence={ECO:0000305};
