Background
Mitogen-activated protein kinases (MAPKs) are activated by various extracellular signals and play crucial roles in regulating cell proliferation, differentiation, survival, and apoptosis (1). MAPK-interacting kinases (Mnks or MKNKs) are direct downstream substrates of MAPK and were first discovered independently by the work of Fukunaga and Hunter (2) and Waskiewicz and Cooper (3). There are 2 Mnks in human, termed Mnk1 and Mnk2. Both Mnks possess a MAPK-binding domain that allows them to bind to and then to be phosphorylated by Erk and p38. The phosphorylation in the T-loop of Mnks stimulates their kinase activity toward a substrate, eukaryotic initiation factor-4E (eIF4E) (2,3). eIF4E is a key component of the translational machinery mediating the initiation of translation, but how phosphorylation of eIF4E regulates translation initiation is still under investigation (4).
