  • Application notesIs unsuitable for WB.
  • Target

    • FunctionMediates the formation of prostaglandins from arachidonate. May have a role as a major mediator of inflammation and/or a role for prostanoid signaling in activity-dependent plasticity.
    • PathwayLipid metabolism; prostaglandin biosynthesis.
    • Sequence similaritiesBelongs to the prostaglandin G/H synthase family.
      Contains 1 EGF-like domain.
    • Post-translational
      S-nitrosylation by NOS2 (iNOS) activates enzme activity. S-nitrosylation may take place on different Cys residues in addition to Cys-561.
    • Cellular localizationMicrosome membrane. Endoplasmic reticulum membrane.
