Abstract:
The zebrafish has become a well-established animal model for the analysis of development and of several disease phenotypes. Several of the favorable traits that make it a popular model organism would also be beneficial for the study of normal and abnormal vertebrate development in which DNA methylation may play a role. We report the determination of the full-length cDNA sequence corresponding to the zebrafish DNA (cytosine-5-) methyltransferase gene, Dnmt1. It is 4,907 bases long and has an open reading frame predicted to encode a 1,499 amino acid protein that is similar in size and sequence to a number of other methyltransferases identified in other organisms.
