ENAM

Enamelin is a protein that in humans is encoded by the ENAM gene.

Dental enamel is a highly mineralized tissue with 85% of its volume occupied by unusually large, highly organized, hydroxyapatite crystals. This highly organized and unusual structure is thought to be rigorously controlled in ameloblasts through the interaction of a number of organic matrix molecules that include enamelin, amelogenin (AMELX; MIM 300391), ameloblastin (AMBN; MIM 601259), tuftelin (TUFT1; MIM 600087), dentine sialophosphoprotein (DSPP; MIM 125485), and a variety of enzymes. Enamelin is the largest protein in the enamel matrix of developing teeth and comprises approximately 5% of total enamel matrix protein.[supplied by OMIM]

Mutations in the ENAM gene can give rise to autosomal dominant Amelogenesis imperfecta, indicating a role in Amelogenesis.
