CC   -!- FUNCTION: Probable accessory potassium channel protein which modulates
CC       the activity of the pore-forming alpha subunit.
CC   -!- SUBUNIT: Forms heteromultimeric complexes with potassium channel alpha
CC       subunits. {ECO:0000305|PubMed:9687064}.
CC   -!- TISSUE SPECIFICITY: Expressed in late-developed leaves with the highest
CC       expression in the flag leaf (at protein level).
CC       {ECO:0000269|PubMed:9687064}.
CC   -!- INDUCTION: Down-regulated in late-developed leaves when grown on
CC       potassium-deficient soil (at protein level).
CC       {ECO:0000269|PubMed:9687064}.
CC   -!- MISCELLANEOUS: In vitro, interacts with the N-terminal part of
CC       A.thaliana KAT1, a voltage-gated potassium channel alpha subunit.
CC   -!- SIMILARITY: Belongs to the shaker potassium channel beta subunit
CC       family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAC50046.1; Type=Frameshift; Evidence={ECO:0000305};
