a CAM kinase of the MAPKKAPK family that can regulate translation. Following activation by MAP kinases, Mnk1 phosphorylates eIF4E at Ser209, increasing its affinity for the 7-methylguanosine-containing mRNA cap. Two MAPK phosphorylation sites in mouse Mnk1 (Thr197 and Thr202) are essential for its kinase activity. Three alternatively spliced human isoforms have been described. Note: This description may include information from UniProtKB.
