Casein Kinase 2 beta (CSNK2B) is a ubiquitous Ser/Thr kinase expressed in all eukaryotes. CSNK2Bis atetramer comprised of 2 catalytic kinase domains, alpha subunits and 2 identical regulatory beta subunits.CSNK2Btakes part incell cycle control, DNA repair,regulation of the circadian rhythm and other cellularprocesses. The beta subunit itself confers stability to the CK2 alpha subunitand is involved in activity and substrate specificity but does not have kinase activity.
Post-translational: Phosphorylated by alpha subunit.
Recombinant Human CSNK2B Protein (rp189349) - SDS-PAGE 3 μg/lane of Recombinant Human CSNK2B Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 26.0 kDa under reducing conditions and non-reducing conditions.
