Kinase activity is measured as the molar amount of phosphate incorporated into the CREBTIDE substrate peptide (KRREILSRRPSYR), per minute per mg protein at 30 °C using a final concentration of 50 μM [32P] ATP.
PKD2 is a novel phorbol ester- and growth factor-stimulated serine/threonine kinase that contains two cysteine-rich motifs at the N terminus, a pleckstrin homology domain, and a catalytic domain. The PKD family of enzymes have been implicated in very diverse cellular functions, including Golgi organization and plasma membrane directed transport, metastasis, immune responses, apoptosis and cell proliferation.
