title: The rat amelogenin gene--some aspects of evolution and expression.
abstract: This study presents data to support the hypothesis that a major portion of the coding sequence of the amelogenin gene may have arisen by tandem duplication of internal sequences which as a consequence has introduced several additional potential RNA splice acceptor sites into the sequence. This duplication of splice sites has led to an increase in the heterogeneity of amelogenin forms found in developing enamel. By screening a rat enamel organ cDNA library for alternatively spliced products, it appears that as much as 20% of the amelogenin mRNA molecules may be alternatively spliced forms.
