SRC FAMILY KINASE HCK WITH BOUND INHIBITOR A-641359

The structure was published by Burchat, A., Borhani, D.W., Calderwood, D.J., Hirst, G.C., Li, B., and Stachlewitz, R.F., in 2006 in a paper entitled "Discovery of A-770041, a Src-Family Selective Orally Active Lck Inhibitor that Prevents Organ Allograft Rejection." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.15 Å and deposited in 2005.

The experimental data on which the structure is based was also deposited.
