- Abstract
- CK2, an acronym derived from the misnomer "casein kinase 2", denotes a ubiquitous and extremely pleiotropic Ser/Thr protein kinase, the holoenzyme of which is composed of two catalytic (alpha and/or alpha') and two noncatalytic beta subunits acting as a docking platform and the multifarious functions of which are still incompletely understood. By combining affinity chromatography and mass spectrometry, we have identified 144 mouse brain proteins that associate with immobilized CK2beta. A large proportion (60%) of the identified proteins had been previously reported to be functionally related to CK2, and a similar proportion have been classified as phosphoproteins with approximately half of these having the features of CK2 targets. A large... (More)

By combining affinity chromatography and mass spectrometry, we have identified 144 mouse brain proteins that associate with immobilized CK2beta. A large proportion (60%) of the identified proteins had been previously reported to be functionally related to CK2, and a similar proportion have been classified as phosphoproteins with approximately half of these having the features of CK2 targets. A large number of the identified proteins ( approximately 40%) either are nuclear or shuttle between the nucleus and cytoplasm, and the biggest functional classes of CK2beta interactors are committed to protein synthesis and degradation (32 proteins) and RNA/DNA interaction (20 proteins). Also well represented are the categories of cytoskeletal/structural proteins (19), trafficking proteins (17), and signaling proteins (14). The identified proteins are examined in relation to their functions and potential as targets and/or regulators of CK2, disclosing in some cases unanticipated links between this kinase and a variety of biochemical events.
