Protein kinase CK2 in complex with DBC

The structure was published by Chilin, A., Battistutta, R., Bortolato, A., et al., Pinna, L.A., Meggio, F., and Moro, S., in 2008 in a paper entitled "Coumarin as attractive casein kinase 2 (CK2) inhibitor scaffold: an integrate approach to elucidate the putative binding motif and explain structure-activity relationships." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.85 Å and deposited in 2007.

The experimental data on which the structure is based was also deposited.

The PDB entry contains the structure of Casein kinase II subunit alpha. This molecule has the UniProt identifier P28523 (CSK2A_MAIZE)search. The sample contained 332 residues which is 100% of the natural sequence. Out of 332 residues 327 were observed and are deposited in the PDB.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule is most likely monomeric.
