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}.
