Amelogenin's a 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's amelogenins. Other significant proteins in enamel are ameloblastins, enamelins, and tuftelins. Function Although not completely understood, the function of amelogenins's believed to be in organizing enamel rods during tooth development. The latest research indicates that this protein regulates the initiation… (More on Amelogenin)
