Structural variability within crystal structures of the free human fascin1 protein. Ribbon representations of molecule A (left panel) and molecule B (right panel) from various crystal structures of human fascin1. Structures shown include wild-type fascin1 from the present study (yellow for molecule A, green for molecule B), wild-type fascin1 from PDB entry 3llp (Chen et al., 2010 ; black), wild-type fascin1 from PDB entry 3p53 (Jansen et al., 2011 ; red) and the inactive S39D mutant from PDB entry 4gov (Yang et al., 2013 ; blue). To highlight conformational differences and domain flexibility, all structures were superposed based on β-trefoil domain 2. The comparisons reveal variations in domain orientations that underline the structural plasticity of fascin1 and its functional regulation. |
