Figure 1. Amelotin isolation and sequences. (A) Identification of an ameloblasts-specific gene fragment by DD-PCR. Two independent preparations of cDNA from ameloblasts (1), odontoblasts (2), dental pulp cells (3), and alveolar osteoblasts (4) were resolved on a 6% polyacrylamide gel and visualized by radioautography. Arrowheads indicate the bands representing the amelotin fragment. (B) cDNA and conceptually translated protein sequence of amelotin. The fragment identified by DD-PCR is underlined. (C) Protein sequence comparison of mouse and human amelotin. Asterisks indicate identical, semicolons highly conserved, and periods similar amino acids. (D) Exon-intron structure and predicted localization of mouse and human amelotin genes. Open squares indicate exons containing non-coding sequences. The relative location of the ameloblastin (Ambn) and enamelin (Enam), as well as the SIBLING gene cluster (Dspp, Dmp1, BSP. MEPE, OPN), is also indicated.
