Figure 3From: The evolution of vertebrate somatostatin receptors and their gene regions involves extensive chromosomal rearrangementsPhylogenetic maximum likelihood tree of the GRIN2 gene family. The ionotropic glutamate receptor 2 (GRIN2) gene family is a neighboring family of the SSTR2, -3 and -5 chromosomal regions. Phylogenetic methods, monophyletic clusters and leaf names as in Figure 2.Back to article page
