21-73 4.97e-10

Amelogenin; Amelogenins play a role in biomineralization. They seem to regulate the formation of crystallites during the secretory stage of tooth enamel development. thought to play a major role in the structural organization and mineralization of developing enamel. They are found in the extracellular matrix. Mutations in X-chromosomal amelogenin can cause Amelogenesis imperfecta.

28-49 4.77e-08

Amelogenins, cell adhesion proteins, play a role in the biomineralisation of teeth; They seem to regulate formation of crystallites during the secretory stage of tooth enamel development and are thought to play a major role in the structural organisation and mineralisation of developing enamel. The extracellular matrix of the developing enamel comprises two major classes of protein: the hydrophobic amelogenins and the acidic enamelins. Circular dichroism studies of porcine amelogenin have shown that the protein consists of 3 discrete folding units: the N-terminal region appears to contain beta-strand structures, while the C-terminal region displays characteristics of a random coil conformation. Subsequent studies on the bovine protein have indicated the amelogenin structure to contain a repetitive beta-turn segment and a "beta-spiral" between Gln112 and Leu138, which sequester a (Pro, Leu, Gln) rich region. The beta-spiral offers a probable site for interactions with Ca2+ ions. Muatations in the human amelogenin gene (AMGX) cause X-linked hypoplastic amelogenesis imperfecta, a disease characterised by defective enamel. A 9bp deletion in exon 2 of AMGX results in the loss of codons for Ile5, Leu6, Phe7 and Ala8, and replacement by a new threonine codon, disrupting the 16-residue (Met1-Ala16) amelogenin signal peptide.

Ameloblastin precursor (Amelin); This family consists of several mammalian Ameloblastin precursor (Amelin) proteins. Matrix proteins of tooth enamel consist mainly of amelogenin but also of non-amelogenin proteins, which, although their volumetric percentage is low, have an important role in enamel mineralisation. One of the non-amelogenin proteins is ameloblastin, also known as amelin and sheathlin. Ameloblastin (AMBN) is one of the enamel sheath proteins which is though to have a role in determining the prismatic structure of growing enamel crystals.
