Kinase Classification: Group STE: Family STE7

STE7 (MAP2K, MEK) kinases are part of the MAPK signaling cascades: they are activated by STE11 (MAP3K) and phosphorylate MAPK kinases. They are typically dual-specificity kinases, and phosphorylate a conserved TxY motif on MAPK.

Major Subfamilies

MEK1

MEK3

MKK4

MEK5

MEK7


Evolution

STE11 kinases are found in almost all eukaryotes, with Plasmodium being a notable exception.
