CC   -!- FUNCTION: Highly selective and weak inward-rectifying potassium
CC       channel. Plays a role in both loading and unloading potassium into/from
CC       the phloem sap. Seems to control sugar loading into phloem via a
CC       voltage-dependent process. Blocked by physiological concentrations of
CC       external calcium and by external acidification. May interact with the
CC       cytoskeleton or with regulatory proteins. Dephosphorylation by PP2CA
CC       not only leads to the inhibition of potassium currents but also to an
CC       increase of the voltage-dependence of the channel. Regulated by the
CC       CBL4/CIPK6 calcium sensor/protein kinase complex via a kinase
CC       interaction-dependent but phosphorylation-independent translocation of
CC       the channel to the plasma membrane. {ECO:0000269|PubMed:12447548,
CC       ECO:0000269|PubMed:12678562}.
CC   -!- SUBUNIT: The potassium channel is probably composed of a homo- or
CC       heterotetrameric complex of pore-forming subunits. Interacts with the
CC       phosphatase PPC2A and the kinase CIPK6. May interact with AKT1, KAT1
CC       and KAT3. Interacts with SLAC1 (PubMed:27002025).

CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC       {ECO:0000269|PubMed:21445098}; Multi-pass membrane protein
CC       {ECO:0000269|PubMed:21445098}. Note=Targeted to the cell membrane when
CC       interacting with CIPK6 and CBL4.
CC   -!- TISSUE SPECIFICITY: Expressed mainly in the phloem tissues throughout
CC       the plant but also, at a lower level, in leaf epiderm, mesophyll and
CC       guard cells. {ECO:0000269|PubMed:10377458, ECO:0000269|PubMed:10852932,
CC       ECO:0000269|PubMed:12034902, ECO:0000269|PubMed:8552711}.
CC   -!- INDUCTION: In shoots, strongly induced by abscisic acid (ABA) treatment
CC       and reduced after NaCl treatment or potassium starvation.
CC       {ECO:0000269|PubMed:12678562}.
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   -!- 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.
CC   -!- PTM: Dephosphorylated by PP2CA.
CC   -!- DISRUPTION PHENOTYPE: Delayed development and flowering.
CC       {ECO:0000269|PubMed:21445098}.
CC   -!- SIMILARITY: Belongs to the potassium channel family. Plant (TC 1.A.1.4)
CC       subfamily. {ECO:0000305}.
