Mitogen-activated protein kinase kinase (also known as MAP2K, MEK, MAPKK) is a dual-specificity kinase enzyme which phosphorylates mitogen-activated protein kinase (MAPK).

MAP2K is classified as EC 2.7.12.2.

There are seven genes:

The activators of p38 (MKK3 and MKK6), JNK (MKK4 and MKK7), and ERK (MEK1 and MEK2) define independent MAP kinase signal transduction pathways.[1] The acronym MEK derives from MAPK/ERK Kinase.[2]

Role in melanoma

[edit]

MEK is a member of the MAPK signaling cascade that is activated in melanoma.[3] When MEK is inhibited, cell proliferation is blocked and apoptosis (controlled cell death) is induced.
