AMELX, AMBN and ENAM are the major matrix proteins of enamel, and play different roles during different developing stages of tooth germs. AMELX may facilitate the growth of crystals in the early mineral stage, and act in the repairing of bone. AMBN may promote the mineralization of enamel matrix, and also keep the shape and size of crystals. ENAM may act in remineralization and promoting the growth of crystals.
