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:
- MAP2K1 (a.k.a. MEK1)
- MAP2K2 (a.k.a. MEK2)
- MAP2K3 (a.k.a. MKK3)
- MAP2K4 (a.k.a. MKK4)
- MAP2K5 (a.k.a. MKK5)
- MAP2K6 (a.k.a. MKK6)
- MAP2K7 (a.k.a. MKK7)
The activators of p38 (MKK3 and MKK6), JNK (MKK4 and MKK7), and ERK (MEK1 and MEK2) define independent MAP kinase signal transduction pathways. The acronym MEK derives from MAPK/ERK Kinase.
