CC -!- FUNCTION: May aid fertilization by loosening the cell wall of the
CC stigma and style, thereby facilitating penetration of the pollen tube.
CC Acts selectively on grass cell walls, which are relatively poor in
CC pectins and xyloglucans and rich in glucuronoarabinoxylans and (1-
CC 3),(1-4)-beta-D-glucans, when compared with cell walls of other
CC angiosperms, including other monocots (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 pollen. {ECO:0000269|PubMed:12913162}.
CC -!- ALLERGEN: Causes an allergic reaction in human. Causes maize pollen
CC allergy (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the expansin family. Expansin B subfamily.
CC {ECO:0000305}.
