Figure 4From: Analysis of the PDZ binding specificities of Influenza A Virus NS1 proteinsThe non-canonical residues of the PBM determine NS1 binding affinity for Dlg. Upper panel. The cartoon shows the last 11 amino acid residues of Avian (A) and Human (H) NS1, together with the non-PDZ-binding mutant of Avian NS1 (Aa), plus the avian human-like (Ah) and the human avian-like (Ha) mutants. Lower panel. GST pulldown assay using these NS1 proteins.Back to article page
