Enzyme Assays for Protein Kinase C Activity
As protein kinase C (PKC) isozymes are implicated in increasing numbers of signal transduction pathways and disease processes, more investigators from different fields have the need to assay PKC activity. A simple in vitro assay suitable for measuring PKC activity in soluble cell extracts is provided here. Like other kinases, PKC catalyzes the transfer of the terminal phosphate from ATP to a protein or peptide substrate. Use of γ-32P-labeled ATP allows this transfer to be monitored by scintillation counting or by autoradiography of the substrate following its removal from the excess ATP.
