MD Simulations MD simulations of the ABL kinase domain were independently launched for ABL-WT, ABL-T315I and ABL-L387M from the inactive form (pdb entry 1IEP), Src-like structure (pdb entry 2G1T) and ... ctive state (pdb entry 1M52).
Materials and Methods Structure Preparation In simulations of the ABL and EGFR kinase domains, we used the following crystal structures from the Protein Data Bank (PDB): pdb entry 1IEP (inactive ABL structure), pdb entry 2G1T (Src-like inactive ABL structure), pdb entry 1M52 (active ABL structure), pdb entry 1XKK (Src/Cdk-like inactive EGFR structure), pdb entry 2GS7 (Src/Cdk-like inactive EGFR structure) and pdb entry 2J6M (active EGFR structure).
The crystal structures of ABL represent the following conformational forms: the Imatinib-bound, inactive structure (pdb entry 1IEP) (A), the Src-like inactive structure (pdb entry 2G1T) (B), and the active structure (pdb entry 1M52) (C).
TMD simulations were carried out for ABL-WT, ABL-T315I and ABL-L387M to model conformational transitions from the Imatinib-bound, inactive state of ABL (pdb entry 1IEP) to the target active ABL conformation (pdb entry 1M52 for ABL-WT and ABL-L387M; pdb entry 2Z60 for ABL-T315I).

Only the ribbon representation of the human ABL kinase domain from 1IEP (chain A) is shown.
The human ABL kinase co-crystallized with imatinib (PDB code 1IEP) was used as reference for the structural superposition of the human ABL co-crystallized with dasatinib (PDB code 2GQG) and of the mouse ABL in complex with the allosteric inhibitor GNF-2 (PDB code 3K5V).

Captured image from the superimposition viewer, which shows the superimposition of an STI-binding pocket of 1IEP to a putative pocket of 2GK9.
We present an example here: similarity between the imatinib (HET: STI)-binding pocket of the tyrosine protein kinase ABL (PDB ID: 1IEP) ( 23 ) and a putative pocket of phosphatidylinositol-4-phosphate 5 (P4P5)-kinase (PDB ID: 2GK9).
