Acts selectively on grass cell walls, which are relatively poor in pectins and xyloglucans and rich in glucuronoarabinoxylans and (1-3),(1-4)-beta-D-glucans, when compared with cell walls of other angiosperms, including other monocots (By similarity).TISSUE SPECIFICITY:Expressed in pollen.ALLERGEN:Causes an allergic reaction in human. Causes maize pollen allergy (By similarity).SIMILARITY:Belongs to the expansin family. Expansin B subfamily.SIMILARITY:Contains 1 expansin-like CBD domain.SIMILARITY:Contains 1 expansin-like EG45 domain. "
