功能
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. -
通路
Lipid metabolism; prostaglandin biosynthesis. -
序列相似性
Belongs to the prostaglandin G/H synthase family.
Contains 1 EGF-like domain. -
翻译后修饰
S-nitrosylation by NOS2 (iNOS) activates enzme activity. S-nitrosylation may take place on different Cys residues in addition to Cys-561. -

Predicted band size: 69 kDa
Observed band size: 75 kDa why is the actual band size different from the predicted?False colour image of Western blot: Anti-COX2 / Cyclooxygenase 2 antibody [EP1978Y] staining at 1/500 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab62331 was shown to bind specifically to COX2 / Cyclooxygenase 2. A band was observed at 75 kDa in wild-type A549 cell lysates with no signal observed at this size in PTGS2 knockout cell line ab280802 (knockout cell lysate ab283825). The band at 65 kDa is a unknown protein as a result of non-specific binding of the antibody. To generate this image, wild-type and PTGS2 knockout A549 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

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).
