Structures and Functions of Leginsulin and Leginsulin-Binding Protein

  • Hisashi Hirano


The involvement of insulin-like proteins in regulatory metabolic mechanism in plants and microorganisms has yet to be fully determined. The authors isolated a soybean seed glycoprotein, basic 7S globulin (Bg), which is capable of binding to bovine insulin and insulin-like growth factors(IGF)-I and II1. Bg showed similarity to the animal insulin receptor in protein structure2, subcellular localization3 and protein kinase activity4. Bg would thus appear to have insulin receptor-like functions.
