General description
Note: 1 KU = 1000 units.
Recombinant, human casein kinase II expressed in E. coli. A cyclic nucleotide-independent serine/threonine protein kinase composed of catalytic α-subunits (M.W. 44 kDa) and regulatory β-subunits (M.W. 26 kDa) in an α2β2- tetramer. This material is one of several forms of native CK-II. Suitable for in vitro phosphorylation of proteins and peptides, phosphopeptide synthesis, characterization of phosphorylating sites, screening of activators and inhibitors, and mechanistic studies. The following substrates have been characterized by CK-II both in vitro and in vivo: nucleolin, RNA polymerase, p53, and SV 40 large T antigen.
