A) Co-crystal structure of DDR1·VX-680 [PDB-entry: 6BRJ] with activation loop (blue), phosphate binding P-loop (red), helix αC (orange). B) The co-crystal structure of DDR1·dasatinib [PDB-entry: 6BSD] with regulatory elements colored as in A. C) Comparison of type I (top, VX-680/dasatinib) and type II (bottom, imatinib/ponatinib) inhibitors binding to Abl (green, right column) and DDR1 kinase (blue, left column). Only the protein surrounding the DFG-motif is shown for clarity. D) Comparison of Φ dihedral angle for Asp747 in DDR1 (blue) and Abl (green) bound to the type I and type II inhibitors in panel C.
