Mitogen-activated protein kinase kinase

Mitogen-activated protein kinase kinase: For other uses, see MKK (disambiguation).

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]
