Gene Information

human ... PTGER4(5734)

Opis ogólny

PTGER4 (prostaglandin E receptor 4) is a prostanoid transmembrane receptor, which has 7 membrane spanning regions. This gene is localized to human chromosome 5p13.1. It is one of the four members of the receptors of prostaglandin E2 (PGE2), and is a G-protein coupled receptor.

Działania biochem./fizjol.

PTGER4 (prostaglandin E receptor 4) binds to prostaglandin E2 (PGE2), and activates Gs protein, which leads to increase of intracellular cAMP levels and decrease of Ca2+ levels. Studies show that activation of this protein prevents the aggregation of platelets and has an anti-thrombotic effect. The expression of PTGER4 is enhanced by transforming growth factor β (TGF-β), which leads to an increase in PGE2-driven virulence of Theileria annulata-transformed macrophages. The SNP rs7720838 in this gene is associated with increased susceptibility to Crohn′s disease. This gene is up-regulated in lymphocytic colitis, and the expression is related with increased tumor necrosis factor-α (TNF-α) expression. PTGER4 has anti-inflammatory activity, where it inhibits the reorganization of junction and cytoskeletons of endothelial cells, promotes the healing of microvascular endothelial monolayers of lungs, and prevents the adhesion and migration of neutrophils.

Cechy i korzyści

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 APREST72466.

Prostaglandin E2 (PGE2) is an important biological mediator involved in the defense against Mycobacterium tuberculosis (Mtb) infection. Previously, we reported that in macrophages (Mϕs), infection with avirulent Mtb H37Ra resulted in inhibition of necrosis by an inhibitory effect on mitochondrial...

Low concentrations of prostaglandin (PG) E(2) enhance platelet aggregation, whereas high concentrations inhibit it. The effects of PGE(2) are mediated through 4 G protein-coupled receptors, termed E-type prostaglindin (EP) receptor EP1, EP2, EP3, and EP4. The platelet-stimulating effect of PGE(2)...
