RL Plant Cell 8:1545-1553(1996).
CC -!- FUNCTION: Probable accessory potassium channel protein which modulates
CC the activity of the pore-forming alpha subunit.
CC {ECO:0000269|PubMed:8837508}.
CC -!- SUBUNIT: Forms heteromultimeric complexes with potassium channel alpha
CC subunits. {ECO:0000305|PubMed:8837508}.
CC -!- TISSUE SPECIFICITY: Expressed in roots, leaves and flowers (at protein
CC level). {ECO:0000269|PubMed:8837508}.
CC -!- SIMILARITY: Belongs to the shaker potassium channel beta subunit
CC family. {ECO:0000305}.
