Figure 4From: The evolutionary history of the SAL1 gene family in eutherian mammalsPositive selection acting on orthologs. Map of the amino acids involved in the binding of ligand [13] on the SAL1 3D structure are in blue, and positively selected sites in pink (PDB: 1GM6). Amino acids shown in a van der Waals representation (orange) were both involved in ligand binding and were positively selected. Positively selected amino acids were identified by PAML computations using site models.Back to article page
