Anti-MAPK3 antibody produced in rabbit

Mitogen-activated protein kinase 3 (MAPK3) is a member of the MAP kinase family and is involved in various cell signalling pathways.

Mitogen-activated protein kinase 3 recombinant protein epitope signature tag (PrEST)

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and 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. We also provide Prestige Antibodies^® protocols and other useful information.

Mitogen-activated protein kinase 3 (MAPK3) is involved actively in signaling modules through which cells transduce extracellular signals into intracellular responses. The different pathways have been associated with the regulation of cellular proliferation, differentiation, angiogenesis, embryo development and tumor invasion. In the Ras/extracellular signal-regulated kinase (ERK) pathway, the p90 ribosomal S6 kinases (RSKs) lie at the terminus of the ERK pathway. RSK activation by ERK requires its interaction through a docking site located near the C terminus of RSK. They form a complex which is further involved in activating and recruiting other proteins downstream for the pathway. In another pathway dealing with cell proliferation and differentiation, Raf phosphorylates and activates MEK1/2, which phosphorylates MAPK3 on Thr183 and Tyr185 in the activation loop resulting in full activation of MAPK3. Phosphorylation and de-phosphorylation of MAPK3 provides a rapid and reversible regulatory system to control its activity.

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.
