Gene Information

human ... PDPK1(5170)

Application

Kinase activity is measured as the molar amount of phosphate incorporated into PDKtide substrate peptide (KTFCGTPEYLAPEVRREPRILSEEEQEMFRDFDYIADWC) per minute per mg protein at 30 °C using a final concentration of 50 microM [32P] ATP.

Biochem/physiol Actions

PDK1 plays a regulatory role in glucose and carbohydrate metabolism. It functions through the PI3K signaling cascade upstream of AKT1 as well as in other pathways involving proliferation, survival and cell migration.

Physical form

Solution of 50 μl in 50 mM Tris-HCl, pH 7.5, 150 mM NaCl, 0.25 mM dithiothreitol (DTT), 0.1 mM EGTA, and 30% glycerol.

Other Notes

Human PDK1 is a 556-residue monomeric enzyme comprised of a catalytic domain that is most similar to the PKA, PKB and PKC subfamily of protein kinases and a C-terminal pleckstrin homology domain.
One unit will incorporate one nanomole of phosphate into the PDK tide substrate (KTFCGTPEYLAPEVRREPRILSEEEQEMFRDFDYIADWC) per minute at 30 °C at pH 7.2 using a final concentration of 50 μM [32P] ATP.
