CC   -!- FUNCTION: May cause loosening and extension of plant cell walls by
CC       disrupting non-covalent bonding between cellulose microfibrils and
CC       matrix glucans. No enzymatic activity has been found. May be required
CC       for rapid internodal elongation in deepwater rice during submergence
CC       (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted, cell wall {ECO:0000250}. Membrane
CC       {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed in roots and flowers.
CC       {ECO:0000269|PubMed:12428004, ECO:0000269|PubMed:16267395}.
CC   -!- SIMILARITY: Belongs to the expansin family. Expansin A subfamily.
CC       {ECO:0000305}.
