Amelogenin is a low-molecular-weight protein found in developing tooth enamel, and it belongs to a family of extracellular matrix (ECM) proteins. Developing enamel contains about 30% protein, and 90% of this is comprised of amelogenins. Although not completely understood, the function of amelogenins is believed to be in organizing enamel rods during tooth development. The latest research indicates that this protein regulates the initiation and growth of hydroxyapatite crystals during the mineral… (More on Amelogenin)
