Structural insight into human CK2alpha in complex with the potent inhibitor ellagic acid

Bioorg Med Chem Lett. 2009 Jun 1;19(11):2920-3. doi: 10.1016/j.bmcl.2009.04.076. Epub 2009 Apr 22.

Abstract

We determined the 2.35-A crystal structure of a human CK2 catalytic subunit (referred to as CK2alpha complexed with the ATP-competitive, potent CK2 inhibitor ellagic acid. The inhibitor binds to CK2alpha with a novel binding mode, including water-mediated hydrogen bonds. This structural information may support discovery of potent CK2 inhibitors.
