Addtional InformationFUNCTION:Might act as a protease inhibitor involved in plant defense responses.TISSUE SPECIFICITY:Expressed in roots, leaves, epidermal layers of elongating stems, meristems and in the vascular system.SIMILARITY:Belongs to the protease inhibitor I3 (leguminous Kunitz-type inhibitor) family.CAUTION:Was originally (PubMed:7559605) thought to be an alpha-L- fucosidase.CAUTION:The nucleotide sequence (X82595) deposited at the EMBL differs from that shown in Ref.1 with the same accession number.
