Recombinant full-length human MEK4 was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. Mitogen-activated protein kinase kinase 4 (MEK4 or MKK4) is a dual specificity kinase of the STE7 family that phosphorylates and activates JNK1 and -2 as well as p38. MKK4 preferentially phosphorylates the tyrosine residue of JNKs. Kinase Enzyme System contains: MEK4 (MAP2K4) Kinase, 10ug (Human, recombinant full-length). MW: ~71kDa. Inactive JNK1 Substrate, 0.1ug/ul. 5X Reaction Buffer, 0.1M DTT.
