General description

The kit provides an easy method for measuring the activity of the different casein kinases by an in vitro phosphorylation of α-casein. The kit includes CK I and CK II specific inhibitors to distinguish between CK I and CK II activities in the biological sample. The kit can be used for CK activity measurement in cell lysates, tissue homogenates, column fractions, or of the purified enzyme

Biochem/physiol Actions

Casein kinases (CK) are highly conserved serine/threonine kinases, ubiquitous in eukaryotic organisms, and defined by their substrate preference for casein. They are insensitive to cyclic nucleotides, Ca2+, and phospholipids. Casein kinases are grouped into two main families, type I and type II, according to their structure, specificity, and response to effectors.

The specificity of casein kinase II has been further defined by analyzing the kinetics of phosphorylation reactions using a number of different synthetic peptides as substrates. The best peptide substrates are those in which multiple acidic amino acids are present...
