General description

Prostaglandin E2 receptor EP4 subtype (PTGER4) is a heptahelical G-protein coupled receptor. It belongs to the seven-transmembrane receptor superfamily. The gene encoding it is located on the chromosome arm 5p.

Biochem/physiol Actions

Prostaglandin E2 receptor EP4 subtype (PTGER4) is involved in anti-inflammatory action by binding of its ligand Prostaglandin E2 in macrophages. This interaction between the ligand and receptor increases intracellular cyclic adenosine monophosphate (cAMP) through a G protein called G-α. cAMP in turn activates protein kinase A (PKA) which phosphorylates other downstream effector proteins like cAMP response element–binding protein (CREB). This pathway occurs during bone formation and other developmental activities. The cytoplasmic domain of PTGER4 also interacts with arrestins and causes receptor internalization. PTGER4 also regulates ovarian carcinoma cell invasion and vascular endothelial growth factor production.

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.
