human ... MKNK2(2872)

General description

MKNK2 (MAP kinase interacting serine/threonine kinase 2) is a serine threonine kinase belonging to the human MAP kinase-interacting kinases group. It consists of a zinc-binding domain and an atypical open conformation region.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project ( as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem/physiol Actions

MKNK2 (MAP kinase interacting serine/threonine kinase 2) is associated with various MAPK-dependent growth factor signaling pathways. It acts in downstream kinase activated by mitogen-activated protein (MAP) kinases in response to mitogens and stress. MKNK2 phosphorylates the cap binding eukaryotic initiation factor 4E (eIF4E) at Ser-209 position during the initiation of mRNA translation, oncogenic transformation and malignant cell proliferation. Studies show it may negatively control arsenic trioxide-dependent apoptosis and antileukemic responses.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.


Corresponding Antigen APREST73483.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
