Prostaglandin Reductase 2 (PTGR2)

PTGR2 is an enzyme involved in the metabolism of prostaglandins. The encoded protein catalyzes the NADPH-dependent conversion of 15-keto-prostaglandin E2 to 15-keto-13,14-dihydro-prostaglandin E2. This protein may also be involved in regulating activation of the peroxisome proliferator-activated receptor. Alternative splicing results in multiple transcript variants. ZADH1 has a domain characteristic of the zinc-containing ADH family , a proline-rich motif, and a putative NADP(+)-binding domain. RT-PCR detected ubiquitous expression of the shorter ZADH1 transcript (ZADH1b), with highest expression in kidney, liver, pancreas, prostate, and heart, followed by lung, skeletal muscle, testis, small intestine, and brain. Expression was low in all other tissues examined.
