Partially Immitation Uno

Posted by kinasepro on February 8, 2007

Maybe this why they call it pim1?

See here, its a kinase without a key hydrogen bond donor. Highlit yellow is the interesting PRO123. ATP and inhibitors generally bind to the peptide NH that is otherwise normally there.


Big deal eh? Well, next time a modeler tells you you have to have a hydrogen bond to the hinge, tell him to put 2OBJ in his pipe and smoke it! 1YI3 is the other ligand/pim complex. While I don’t know the activity of these pyridone compounds or of the ligand in 1YI3, BindingDB has 5 compounds 4 of which are 150nM and less. SS and the BIM’s appear to be very active.  I guess when your competition is ATP, and ATP can’t find that H-Bond either…
