Human 3-phosphoinositide-dependent protein kinase (PDK1), GenBank Accession No. NM_002613, full length with N-terminal GST-tag, MW=89 kDa, expressed in a Baculovirus infected Sf9 cell expression system.
host species: Sf9 cells
Host species: Sf9 cells
Specific activity: >=100 pmol/min/ug
Background
PDK1 (3-phosphoinositide-dependent protein kinase) is activated by the presence of PtdIns(3,4,5)P3 or PtdIns(3,4)P2. PDK1 then activates protein kinase B (PKB) which, in turn, inactivates glycogen synthase kinase-3 (GSK3). The phosphorylation of other proteins by PKB and GSK3 is likely to mediate many of the intracellular actions of insulin. Thus, PDK1 plays a key role in mediating many of the actions of the second messenger(s) PtdIns(3,4, 5)P3 and/or PtdIns(3,4)P2. The human PDK1 is a 556-residue monomeric enzyme comprising of a catalytic domain that is most similar to the PKA, PKB and PKC subfamily of protein kinases.

Notes
Assay was done in Kinase buffer containing 0.2 mM DTT using PDKtide substrate (0.1 mg/ml) and 20 uM ATP. Reaction was done at 30°C for 45 min. Amount of ATP transferred was measured using Kinase-Glo reagent (Promega)
