Function | Dual function enzyme which exhibits both isomerase and lyase activities. Its catalytic activity is altered by the presence or absence of the cofactors glutathione (GSH) and heme. The GSH-heme complex-bound enzyme (mPGES-2h) acts as a lyase and catalyzes the degradation of prostaglandin E2 H2 (PGH2) to 12(S)- hydroxy-5(Z),8(E),10(E)-heptadecatrienoic acid (HHT) and malondialdehyde (MDA) while the GSH-heme complex-free enzyme (mPGES-2) acts as an isomerase and catalyzes the isomerization of PGH2 into the more stable prostaglandin E2 (PGE2) form (By similarity). {ECO:0000250}. | ||||||||||||||||||
Subcellular Localization | Golgi apparatus membrane {ECO:0000269PubMed:12835322}; Single-pass membrane protein {ECO:0000269PubMed:12835322}.Prostaglandin E synthase 2 truncated form: Cytoplasm, perinuclear region. Note=Synthesized as a Golgi membrane-bound protein, which is further cleaved into the predominant soluble truncated form. The truncated form is cytoplasmic and is enriched in the perinuclear region. | ||||||||||||||||||

Tissue Specificity | Widely expressed. Expressed in the heart, including apex, inter-ventricular septum, both atria and ventricles, but not in the aorta. Also expressed in fetal heart. Detected in various regions of the brain: cerebellum; occipital, frontal and parietal lobes. Also expressed in the lymph nodes, skeletal muscle, kidney and trachea, but not in the thymus or lung. Overexpressed in colorectal cancer. {ECO:0000269PubMed:11866447}. | ||||||||||||||||||
