What is "amelogenin"

n. (context biochemistry English) A protein found in the enamel of tooth

Amelogenin is the name for a series of closely related proteins involved in amelogenesis, the development of enamel. They are a type of extracellular matrix (ECM) protein, which, together with ameloblastins, enamelins, and tuftelins direct the mineralization of enamel to form a highly organized matrix of rods, interrod crystal, and protein. Although the precise role of amelogenin(s) in regulating the mineralization process is unknown, it is known that amelogenins are abundant during amelogenesis. Developing human enamel contains about 30% protein, 90% of which are amelogenins.
