Gene Information

human ... PPM1E(22843)

General description

The gene PPM1E (protein phosphatase Mg2+/Mn2+ dependent 1E) is mapped to human chromosome 17q22. It belongs to PPM family. PPM1E is abundantly expressed in brain and testis.


Protein phosphatase 1E recombinant protein epitope signature tag (PrEST)


All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)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.

Biochem/physiol Actions

The autophosphorylation of p21 (Cdc42/Rac)-activated kinase PAK is crucial for mediating cellular functions. The protein phosphatase Mg2+/Mn2+ dependent 1E (PPM1E) was identified as the binding partner for the PAK interacting guanine nucleotide exchange factor PIX. The dephosphrylation action of PPM1E blocks in vivo effects of active PAK. PPM1E is also a phosphatase for 5′-AMP-activated protein kinase (AMPK). Activation and phosphorylation of AMPK is important for treatment of type-2 diabetes.

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.

The Rho GTPases are involved in many signaling pathways and cellular functions, including the organization of the actin cytoskeleton, regulation of transcription, cell motility, and cell division. The p21 (Cdc42/Rac)-activated kinase PAK mediates a number of biological effects downstream of...

Activation of 5'-AMP-activated protein kinase (AMPK) is believed to be the mechanism by which the pharmaceuticals, metformin and phenformin, exert their beneficial effects for treatment of type 2 diabetes. These biguanide drugs elevate 5'-AMP, which allosterically activates AMPK and promotes...
