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.
