... dogfish actin by sequencing. Discussion We describe here the cloning of the first MC receptor in spiny dogfish. The phylogenetic analysis indicates that the new receptor is an ortholog of the MC4 ... brain stem but not in cerebellum (Fig. 6). The presence of MC4 in the hypothalamus is not surprising. This receptor is expressed in hypothalamus in all species inves- tigated and i...
