CC -!- FUNCTION: Regulates membrane-cell wall junctions and localized cell
CC wall deposition. Required for establishment of the Casparian strip
CC membrane domain (CSD) and the subsequent formation of Casparian strips,
CC a cell wall modification of the root endodermis that determines an
CC apoplastic barrier between the intraorganismal apoplasm and the
CC extraorganismal apoplasm and prevents lateral diffusion (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homodimer and heterodimers. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}. Note=Very restricted localization following a
CC belt shape within the plasma membrane which coincides with the position
CC of the Casparian strip membrane domain in the root endodermis.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the Casparian strip membrane proteins (CASP)
CC family. {ECO:0000305}.
