Protein

MAP kinase-interacting serine/threonine-protein kinase 1

Gene

Mknk1

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

May play a role in the response to environmental stress and cytokines. Appears to regulate translation by phosphorylating EIF4E, thus increasing the affinity of this protein for the 7-methylguanosine-containing mRNA cap.1 Publication

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.1 Publication

Cofactori

Mg2+1 Publication

Enzyme regulationi

Phosphorylated and activated by the p38 kinases and kinases in the Erk pathway.1 Publication

Post-translational modificationi

Dual phosphorylation of Thr-209 and Thr-214 activates the kinase. Phosphorylation of Thr-344 activates the kinase. MAPK3/ERK1 is one of the kinases which activate MKNK1/MNK1. Phosphorylation by PAK2 leads to a reduced phosphorylation of EIF4G1 (By similarity).By similarity
