Background

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 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 (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).

MKK3和MKK6是两种密切相关的双特异性蛋白激酶,能够激活p38 MAPK(1-5)。MKK3和MKK6能够通过磷酸化p38 MAPK的活化位点Thr-Gly-Tyr从而使p38 MAPK激活,但不能磷酸化或激活Erk1/2或SAPK/JNK。p38 MAPK的磷酸化能够显著提高其磷酸化蛋白底物的能力,这些底物包括ATF-2和Elk-1。MKK3和MKK6能被不同形式的细胞压力和炎症细胞因子激活(4,5)。通过磷酸化MKK3的Ser189和Thr193位点(2)以及MKK6的Ser207和Thr211位点(4,5)可以激活MKK3和MKK6。
