MEK

MEK

MEK (Mitogen-activated protein kinase kinase, MAPKK) is a kinase enzyme which phosphorylates mitogen-activated protein kinases (MAPKs).The downstream transcription factors that control responses like stress signaling, pathogen response, and hormone signaling are phosphorylated as a result of the activated MAPK.

The final protein in the cascade, a MAPK (ERK, p38, or JNK), is activated by the MAPKKK by phosphorylating a serine or threonine residue on a MAPKK. Mitogen-activated protein kinase kinase 3 (MKK3), MKK6, and occasionally MKK4 are primarily responsible for activating the p38 MAPK. Two upstream MAP2Ks, MKK4 and MKK7, control the JNK. Raf and Ras are activated by the highly homologous kinases MEK1 and MEK2, which then activate ERK mitogen-activated protein kinases.
