Protein kinase CK2 is a constitutively active serine/threonine kinase that is overexpressed in several human cancers, and by virtue of the vast number of putative substrates in the phosphoproteome, is implicated in the regulation of numerous cellular processes. Consequently, CK2 is an emerging therapeutic target with many CK2 inhibitors having been developed. An example of one such inhibitor is the clinical stage compound CX-4945. Although highly selective for CK2, the ATP competitive CX-4945 has demonstrated affinity for other kinases. Unique features of the catalytic pocket of CK2 have allowed for the development of inhibitor refractory mutants, which have since been …

Protein phosphorylation is controlled by protein kinases, and represents a critical signaling mechanism involved in the regulation of fundamental biological processes. Furthermore, the aberrant regulation of kinase activity is implicated in diseases such as cancer and has resulted in efforts to target kinases therapeutically. Protein kinase CK2, although frequently considered constitutively active, has emerged as a clinical target on the basis of its altered expression in different types of human cancers and its regulatory participation in multiple biological processes. In fact, CX-4945, a small molecule ATP-competitive inhibitor of CK2 has advanced to clinical trial and has been widely used to …
