| Outline of Final Research Achievements |
Artificial ligands that induce the dimerization of growth factor receptors may be applicable to regenerative medicine, and generation of artificial ligands that have unique and novel biological activities may be possible. We here investigated signal activation by hetero-dimerization between different growth factor receptors. The split luciferase fusion protein system and observation of receptor molecules by atomic force microscopy were performed and determined to be appropriate for evaluation of growth factor receptor dimerization. Hetero-dimer formation between MET, RET, and IGF receptors was induced in cultured cells using FKBP/FRB fusion receptors, however, activation of these receptor and downstream signaling molecules were not seen. Combination of other growth factor receptors seemed to be required to further clarify possibility for generation of artificial ligands capable of inducing hetero-receptor dimerization and activation.
