Protein

MAP kinase-interacting serine/threonine-protein kinase 2

Gene

mknk2

Organism
Xenopus tropicalis (Western clawed frog) (Silurana tropicalis)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript 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 (By similarity).By similarity

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Cofactori

Protein has several cofactor binding sites:
  • Mg2+By similarity
  • Zn2+By similarityNote: Binds 1 zinc ion per subunit.By similarity
