PTGES2 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. Recombinant corresponding to aa1-186 from human PTGES2, fused to His-tag at N-terminus expressed in E. coli.
