Strain development Developed by Rikiro Fukunaga, Graduate School of Frontier Biosciences, Osaka University in 2003. A neomycin selection cassette replaced a fragment from 5 to 6 exons of the Mnk1 and a fragment of 5 to 9 exons of the Mnk1, respectively. R1 ES cells were used. The mutant mice are crossed to C57BL/6.  
Strain description Mnk1 gene knockout mice (RBRC01512), Mnk2 gene knockout mice (RBRC01513), Mnk1 and Mnk2 genes double knockout mice (RBRC01514). Mnk1 and Mnk2 (MAP kinase-interacting serine/threonine kinase 1 and 2) genes are protein kinases that are directly phosphorylated and activated by extracellular signal-regulated kinase or p38 mitogen-activated protein kinases. These genes are essential for constitutive and inducible phosphorylation of eukaryotic initiation factor 4E, but not for cell growth or development. This strain is useful for elucidation of the role of the functions of Mnk1 and Mnk2 genes. Mnk1 homozygous, Mnk2 homozygous and Mnk1/Mnk2 double homozygous knockout mice are viable and fertile.
