1m2p Summary


Crystal structure of 1,8-di-hydroxy-4-nitro-anthraquinone/CK2 kinase complex

The structure was published by De Moliner, E., Moro, S., Sarno, S., et al., Zanotti, G., Pinna, L.A., and Battistutta, R., in 2003 in a paper entitled "Inhibition of protein kinase CK2 by anthraquinone-related compounds. A structural insight" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2002.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of Casein kinase II, alpha chain. This molecule has the UniProt identifier P28523 (CSK2A_MAIZE)search. The sample contained 325 residues which is 98% of the natural sequence. Out of 325 residues 325 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.
