Target
-
Function
Mediates 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. -
Pathway
Lipid metabolism; prostaglandin biosynthesis. -
Sequence similarities
Belongs to the prostaglandin G/H synthase family.
Contains 1 EGF-like domain. -
Post-translational
modificationsS-nitrosylation by NOS2 (iNOS) activates enzme activity. S-nitrosylation may take place on different Cys residues in addition to Cys-561. -
Cellular localization
Microsome membrane. Endoplasmic reticulum membrane. - Information by UniProt

Exposure times
Lane 1 and 2: 5.5 seconds
Lane 3: 3.25 secondsWe are unsure as to the
identity of the extra band in HCT 116 and MCF7.
The expression profile observed in HCT 116 and MCF7 are consistent with the literatures (PMID: 14739610, PMID: 24325753, PMID: 16997132).
