| Addtional Information | FUNCTION:N-acetyl-D-galactosamine specific lectin. Bark lectins are storage protein that probably maintains stocks of nitrogen during dormant period. Self-aggregatable molecules that can bind their own carbohydrate side chains. They could also play a role in the plant's defense against phytophagous invertebrates or herbivorous higher animals.SUBUNIT:RPbAI is composed of two polypeptides, A and B, that associate into five different tetrameric isolectins. The A4 combination is the only one devoid of agglutination activity.Isoform B4 displays maximal agglutination activity.TISSUE SPECIFICITY:Strong expression in seed. Lower levels in the flower, and the bark of the roots. No expression in leaf. The lectin accumulates in the inner bark in autumn.SIMILARITY:Belongs to the leguminous lectin family. |
