The protein encoded by this gene 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 (GATE). Multiple transcript variants have been found for this gene. [provided by RefSeq].
Function:
Isomerase that catalyzes the conversion of unstable intermediate of prostaglandin E2 H2 (PGH2) into the more stable prostaglandin E2 (PGE2) form (By similarity). May also have transactivation activity toward IFN-gamma (IFNG), possibly via an interaction with CEBPB; however, the relevance of transcription activation activity remains unclear.
Subunit:
Homodimer. May interact with CEBPB.
Subcellular Location:
Golgi apparatus membrane; Single-pass membrane protein. Nucleus. Note=According to PubMed:12050152, some fraction may be nuclear. Prostaglandin E synthase 2 truncated form: Cytoplasm. Note=Synthetized as a Golgi membrane-bound protein, which is further cleaved into the predominant soluble truncated form.
Tissue Specificity:
Widely expressed. Expressed in brain, heart, liver, colon and lung.
Similarity:
Belongs to the GST superfamily.
Contains 1 glutaredoxin domain.
Contains 1 GST SLCterminal domain.

Blank control:A549.
Primary Antibody (green line): Rabbit Anti-PTGES2 antibody (SL2639R)
Dilution: 1μg /10^6 cells;
Isotype Control Antibody (orange line): Rabbit IgG .
Secondary Antibody : Goat anti-rabbit IgG-PE
Dilution: 1μg /test.
Protocol
The cells were fixed with 4% PFA (10min at room temperature)and then permeabilized with 20% PBST for 20 min at-20℃.
