Enamelin is an enamel matrix protein (EMPs), that in humans is encoded by the ENAMgene.[5][6] It is part of the non-amelogenins, which comprise 10% of the total enamel matrix proteins.[7] It is one of the key proteins thought to be involved in amelogenesis (enamel development). The formation of enamel's intricate architecture is thought to be rigorously controlled in ameloblasts through interactions of various organic matrix protein molecules that include: enamelin, amelogenin, ameloblastin, tuftelin, dentine sialophosphoprotein, and a variety of enzymes. Enamelin is the largest protein (~168kDa) in the enamel matrix of developing teeth and is the least abundant (encompasses approximately 1-5%) of total enamel matrix proteins.[6] It is present predominantly at the growing enamel surface.
