== Publication Abstract from PubMed ==
 +
A truncated form of the regulatory subunit of the protein kinase CK2beta (residues 1-178) has been crystallized in the presence of a fragment of the cyclin-dependent kinase inhibitor p21WAF1 (residues 46-65) and the structure solved at 2.9 A resolution by molecular replacement. The core of the CK2beta dimer shows a high structural similarity with that identified in previous structural analyses of the dimer and the holoenzyme. However, the electron density corresponding to the substrate-binding acidic loop (residues 55-64) indicates two conformations that differ from that of the holoenzyme structure [Niefind et al. (2001), EMBO J. 20, 5320-5331]. Difference electron density near the dimerization region in each of the eight protomers in the asymmetric unit is attributed to between one and eight amino-acid residues of a complexed fragment of p21WAF1. This binding site corresponds to the solvent-accessible part of the conserved zinc-finger motif.
