Amelogenin gene similarity in vertebrates : DNA sequences encoding amelogenin seem to be conserved during evolution

Mouse amelogenin cDNA was used in hybridization assays with genomic DNA, cut with the restriction enzyme Eco RI, from the edentulous chicken (Gallus domesticus), the monophyodont mouse (as control), diphyodont man, and the polyphyodont fishes Atlantic salmon (Salmo salar) and seawolf (Anarrhichas lu...

Description
Summary:Mouse amelogenin cDNA was used in hybridization assays with genomic DNA, cut with the restriction enzyme Eco RI, from the edentulous chicken (Gallus domesticus), the monophyodont mouse (as control), diphyodont man, and the polyphyodont fishes Atlantic salmon (Salmo salar) and seawolf (Anarrhichas lupus). The hybridization assay was performed under stringent conditions with non-radioactive probes. Hybridization was obtained with mouse (6.4-kb band), man (9-kb and 13-kb bands), and seawolf (18-kb band) genomic DNA. This demonstrates DNA sequence similarities between these species, and supports the theory that DNA sequences encoding enamel proteins appear to be highly conserved during the evolution of vertebrates. Lack of hybridization in salmon and chicken may be due to sequence divergences or structural differences in an amelogenin gene analog, or it may be that no amelogenin gene is present in these animals.
