MKK3 and MKK6 are two closely related dual-specificity protein kinases that activate p38 MAP kinase (1-5).
MKK3 and MKK6 both phosphorylate and activate p38 MAP kinase at its activation site Thr-Gly-Tyr but do not phosphorylate or activate the two other MAP kinases, Erk1/2 or SAPK/JNK.
Phosphorylation of p38 MAP kinase dramatically stimulates the ability of p38 MAP kinase to phosphorylate protein substrates such as ATF-2 and Elk-1.
MKK3 and MKK6 are both activated by different forms of cellular stress and inflammatory cytokines (4,5).
Activation of MKK3 and MKK6 occurs through phosphorylation of serine and threonine residues at sites Ser189 and Thr193 for MKK3 (2), and Ser207 and Thr211 for MKK6 (4,5).
