MAP kinase-interacting serine/threonine-protein kinase 2 is an enzyme that in humans is encoded by the MKNK2 gene.^[5]^[6]

Interactions

MNK2 has been shown to interact with MAPK1^[7]^[8] and Eukaryotic translation initiation factor 4 gamma.^[7]

MNK2 has been identified as a therapeutic target for diabetes. Specifically, blocking MNK2 interaction with eIF4G has been shown to boost protein synthesis and promote beta cell regeneration.^[9]
