Sertoli Cell Prostaglandin D2 Synthetase Is a Multifunctional Molecule: Its Expression and Regulation1.

PGD2 synthetase (PGD-S; PGH2 D-isomerase; EC 5.3.99.2) is a bifunctional protein first identified in the mammalian brain. It acts as a PGD2-producing enzyme and a retinoid transporter. PGD-S is present in the testis, where its protein and messenger RNA levels are similar to those in the brain. In view of its diversified regulatory functions, we investigated… CONTINUE READING
