Amelogenins are the most abundant extracellular matrix proteins secreted by ameloblasts during tooth development and are important for enamel formation. Recently, amelogenins have been detected not only in ameloblasts, which are differentiated from the epithelial cell lineage, but also in other tissues, including mesenchymal tissues at low levels, suggesting that amelogenins possess other functions in these tissues. The therapeutic application of an enamel matrix derivative rich in amelogenins resulted in the regeneration of cementum, alveolar bone, and periodontal ligament (PDL) in the treatment of experimental or human periodontitis, indicating the attractive potential of amelogenin in hard tissue formation. In addition, a full-length amelogenin (M180) and leucine-rich amelogenin peptide (LRAP) regulate cementoblast/PDL cell proliferation and migration in vitro. Interestingly, amelogenin null mice show increased osteoclasto-genesis and root resorption in periodontal tissues. Recombinant amelogenin proteins suppress osteoclasto-genesis in vivo and in vitro, suggesting that amelogenin is involved in preventing idiopathic root resorption. Amelogenins are implicated in tissue-specific epithelial-mesenchymal or mesenchymal-mesenchymal signaling ; however, the precise molecular mechanism has not been characterized. In this review, we first discuss the emerging evidence for the additional roles of M180 and LRAP as signaling molecules in mesenchymal cells. Next, we show the results of a yeast two-hybrid assay aimed at identifying protein-binding partners for LRAP We believe that gaining further insights into the signaling pathway modulated by the multifunctional amelogenin proteins will lead to the development of new therapeutic approaches for treating dental diseases and disorders.
