Microsomal prostaglandin E synthase-2 (mPGES-2)[5][6] or Prostaglandin E synthase 2 is an enzyme that in humans encoded by the PTGES2 gene located on chromosome 9.[7][8] The protein encoded by this gene is a membrane-associated prostaglandin E synthase, which catalyzes the conversion of prostaglandin H2 to prostaglandin E2. This protein also has been shown to activate the transcription regulated by a gamma-interferon-activated transcription element (GATE). Multiple transcript variants have been found for this gene.[9]

Structure

Microsomal prostaglandin E synthase type-2 (mPTGES2) has been crystallized with an anti-inflammatory drug indomethacin (IMN).[10] The N-terminal of mPTGES2 is attached to the lipid membrane and the two hydrophobic pockets connected to form a V shape are located in the bottom of a large cavity for IMN binding. The mPTGES2 exists in a dimer.[10]

Function

The gene encoding the PTGES2 protein contains 10 exons. The PTGE2 protein encoded by the gene is a 33-kDa membrane-associated [11] prostaglandin E synthase that is thought to be targeted to the Golgi apparatus as well as the mitochondrion within the cell. Prostaglandin E synthase catalyzes the conversion of prostaglandin H2 to prostaglandin E2. The particular reaction catalyzed by PTGE2 is thought to be:

(5Z,13E)-(15S)-9-alpha,11-alpha-epidioxy-15-hydroxyprosta-5,13-dienoate = (5Z,13E)-(15S)-11-alpha,15-dihydroxy-9-oxoprosta-5,13-dienoate.[12]

The PTGE2 protein functions in part of the prostaglandin synthesis pathway, which forms a component of the overall lipid synthesis mechanism in the human body. The activity of PTGES2 is thought to be increased in the presence of sulfhydril coumpounds, in particular dithiothreitol.[13]

The PTGE2 protein also has been shown to activate the transcription regulated by an interferon-gamma gamma-interferon-activated transcription element (GATE).[8]

Model organisms have been used in the study of PTGES2 function. A conditional knockout mouse line, called Ptges2tm1a(EUCOMM)Wtsi[18][19] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute.[20][21][22]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[16][23] Twenty two tests were carried out on mutant mice, but no significant abnormalities were observed.[16]

Clinical significance

The excess production of prostaglandin E 2 is known to contribute to inflammatory diseases which includes rheumatoid arthritis, atherosclerosis, and cancer.[24][25] Furthermore, naturally occurring polymorphisms of PTGES2 have been shown to be associated with increased risks for diabetes mellitus and metabolic syndromes.[26][27]

As such, pharmacological inhibition of prostaglandin E 2 production by synthetic minor prenylated chalcones and flavonoids has potential therapeutic viability.[24] It has been shown that the synthesis of prostaglandin E 2 in the endothelial cells of the brain is important for inflammation-induced fever.[28] Additionally, investigators have observed elevations in cell doubling rates for several cancer cell types in the presence of prostaglandin E 2 –producing cell lines.[29]
