Novel iguana amelogenin gene cDNA structure.

Abstract

<p>Analysis of novel iguana amelogenin sequence revealed the full-length amelogenin cDNA containing 7 exons including exon 1, 2, 3, 5, X, 6, and 7 (exon numbers is relative to published mammalian amelogenin exon numbers). Different from amelogenin genes of all species so far, an unique exon named exon X between exon 5 and exon 6 was detected; Similar to other species, no corresponding sequence elements were detected resembling exon 4, suggesting that amelogenin exon 4 is skipped or deleted in <i>Ctenosaura similis</i>.</p
