== Publication Abstract from PubMed == | |||
Protein kinase CK2 (CK2), a constitutively active serine/threonine kinase, is involved in a variety of roles essential to the maintenance of cellular homeostasis. Elevated levels of CK2 expression results in the dysregulation of key signaling pathways that regulate transcription, and has been implicated in cancer. The adenosine-5'-triphosphate-competitive inhibitor CX-4945 has been reported to show broad spectrum anti-proliferative activity in multiple cancer cell lines. Although the enzymatic IC(50) of CX-4945 has been reported, the thermodynamics and structural basis of binding to CK2alpha remained elusive. Presented here are the crystal structures of human CK2alpha in complex with CX-4945 and adenylyl phosphoramidate at 2.7 and 1.3A, respectively. Biophysical analysis of CX-4945 binding is also described. This data provides the structural rationale for the design of more potent inhibitors against this emerging cancer target. | |||
