Mitogen-activated protein kinase kinase [sic] (also known as MAP2K) is a kinase enzyme which phosphorylates mitogen-activated protein kinase (MAPK).
MAP2K is classified as EC 2.7.12.2.
There are seven genes:
- MAP2K1 (aka MEK1)
- MAP2K2 (aka MEK2)
- MAP2K3 (aka MKK3)
- MAP2K4 (aka MKK4}
- MAP2K5 (aka MKK5)
- MAP2K6 (aka MKK6)
- MAP2K7 (aka MKK7)
The activators of p38 (MKK3 and MKK6), JNK (MKK4 and MKK7), and ERK (MEK1 and MEK2) define independent MAP kinase signal transduction pathways.[1]
