Background Information

COX2 (Prostaglandin G/H synthase 2, PTGS2) mediates the formation of prostaglandins from arachidonate. Its subunit structure is homodimer. The fully N-glycosylated PTGS2 is 72-74 kDa and the aglycosylated is 66 kDa(PMID:19656660 ). It also expresses a band of 39 kDa after unspecific cleavage(PMID:17509125 ). The 50 kDa band of fragmented PTGS2 has also previously been detected in AD brains(PMID:14724276 ).
