Protein kinase CK2 in complex with tetrabromobenzoimidazole K17, K22 and K32 inhibitorsProtein kinase CK2 in complex with tetrabromobenzoimidazole K17, K22 and K32 inhibitors
Structural highlights
FunctionCSK2A_MAIZE Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. The alpha chain contains the catalytic site. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedCK2 is a highly pleiotropic Ser/Thr protein kinase that is able to promote cell survival and enhance the tumour phenotype under specific circumstances. We have determined the crystal structure of three new complexes with tetrabromobenzimidazole derivatives that display K(i) values between 0.15 and 0.30 microM. A comparative analysis of these data with those of four other inhibitors of the same family revealed the presence of some highly conserved water molecules in the ATP-binding site. These waters reside near Lys68, in an area with a positive electrostatic potential that is able to attract and orient negatively charged ligands. The presence of this positive region and two unique bulky residues that are typical of CK2, Ile66 and Ile174, play a critical role in determining the ligand orientation and binding selectivity. The ATP-binding site of protein kinase CK2 holds a positive electrostatic area and conserved water molecules.,Battistutta R, Mazzorana M, Cendron L, Bortolato A, Sarno S, Kazimierczuk Z, Zanotti G, Moro S, Pinna LA Chembiochem. 2007 Oct 15;8(15):1804-9.
