CC -!- FUNCTION: High-affinity potassium transporter required for tip growth
CC of root hairs. {ECO:0000269|PubMed:11158535}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Detected at very low levels in roots, stems, leaves
CC and flowers of mature plants. {ECO:0000269|PubMed:9477571}.
CC -!- DEVELOPMENTAL STAGE: Highly expressed in roots in the early stage of
CC seedlings growth.
CC -!- DISRUPTION PHENOTYPE: Loss-of-function mutation results in the arrest
CC of root hair growth. {ECO:0000269|PubMed:11158535}.
CC -!- SIMILARITY: Belongs to the HAK/KUP transporter (TC 2.A.72.3) family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAA23030.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
CC Sequence=CAB79319.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
