ATP Binding Sites on Protein Kinases

This sample shows that same inhibitor can bind different kinases; same kinase binding site can accept different molecules.

• Crystal structure of pyrazole-benzimidazole fragment complexes with Aurora A. (PDB ID = 2W1G)
• ATP Binding sites on protein kinases is described by PFSC

 

• With PBSDD technology, 12 targets was found with similar binding sites after screening the kinases library of protein structures. The PFSC displays the folding conformations.

• 

 

 

 

• Images of three-dimensional structures of 12 protein kinases from Protein Databank (PDB). 12 structures belong to different kinase groups, and each Kinses bind to different inhibitors.  Aurora A: 2W1G, 2W1F, 2W1D, 2W1C, 2W1E, 1OL7, 1MQ4, 1OL5, 2J50 and 1OL6; JAK2: 2W1I; CDK2: 2W1H.

 

 

 

 

 

• 12 binding site images, core residues, sequences and PFSC of 12 ATP binding sites. 12 structures belong to different kinase groups, and each Kinase bind to different inhibitors.  Aurora A: 2W1G, 2W1F, 2W1D, 2W1C, 2W1E, 1OL7, 1MQ4, 1OL5, 2J50 and 1OL6; JAK2: 2W1I; CDK2: 2W1H

 

 

 

 

 

 

 

• 12 ATP inhibitors images.  Each inhibitors exists on perspective ATP binding site on left figure.  Compound 1-10 binds to Aurora A: 2W1G, 2W1F, 2W1D, 2W1C, 2W1E, 1OL7, 1MQ4, 1OL5, 2J50 and 1OL6; JAK2: 2W1I; CDK2: 2W1H.
