DNA sequence for cloned cDNA for murine amelogenin reveal the amino acid sequence for enamel-specific protein.

Abstract

Enamel is the unique and highly mineralized extracellular matrix that covers vertebrate teeth. Amelogenin proteins represent the predominate subfamily of gene products found in developing mammalian enamel, and are implicated in the regulation of the formation of the largest hydroxyapatite crystals in the vertebrate body. Previous attempts to isolate, purify and characterize amelogenins extracted from developing matrix have proven difficult. We now have determined the DNA sequence for a cDNA for the 26-kDa class of murine amelogenin and deduced its corresponding amino acid sequence. The murine amino acid sequence is homologous to bovine or porcine amelogenins extracted from developing enamel matrices. However, an additional 10-residues were found at the carboxy terminus of the murine amelogenin. This is the most complete sequence database for amelogenin peptides and the only DNA sequence for enamel specific genes.
