The prototype member of this family, designated MAP kinase kinase, or MEK-1, specifically phosphorylates the MAP kinaseegulatory threonine and tyrosine residues present in thehr-Glu-Tyr motif of ERK.
A second MEK family member, MEK-2, resembles MEK-1 in its substrate specificity.
MEK-3 (or MKK-3) functions to activate p38 MAP kinase, and MEK-4 (also called SEK1 or MKK-4) activates both p38 and JNK MAP kinases.
MEK-5 appears to specifically phosphorylate ERK5, whereas MEK-6hosphorylates p38 and p38b.
MEK-7 (or MKK-7) phosphorylates and activates the JNK signal transduction pathway.
