Protein Structure
UniProt Annotation
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.
Disease Associations
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}.
