CC -!- FUNCTION: Causes 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 (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall. Membrane; Peripheral
CC membrane protein.
CC -!- SIMILARITY: Belongs to the expansin family. Expansin A subfamily.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAB09382.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
