| Introduction | MKK3 and MKK6 are two closely related dual-specificity protein kinases that activate p38 MAP kinase. MKK3 and MKK6 both phosphorylate and activate p38 MAP kinase at its activation site, Thr-Gly-Tyr, but do not phosphorylate or activate Erk1/2 or SAPK/JNK. Phosphorylation of p38 MAP kinase dramatically stimulates its ability 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. Activation of MKK3 and MKK6 occurs through phosphorylation at Ser189 and Thr222 on MKK3 and Ser207 and Thr211 on MKK6.Three alternatively spliced transcript variants of MKK3 encoding distinct isoforms have been reported. Isoform B utilizes a different start codon compared to isoform C resulting in the production of a N-terminal segment of isoform B which is shorter and distinct from isoform C. MKK3b is the predominant form of MKK3 and strongly activates p38 MAP kinase (6) |
