Prostaglandin D synthase (PGDS) catalyzes the isomerization of PGH2 to produce PGD2. PGD2 induces sleep, regulates nociception, inhibits platelet aggregation, and acts as an allergic mediator. Two distinct types of PGDS have been identified, namely the lipocalin type enzyme (β-trace) and the hematopoietic enzyme.1,2 Lipocalin-type PGDS is localized in the central nervous system, genital organs of various mammals and the human heart.1,3,4,5 Patients with chronic renal failure and hypertension exhibit elevated amounts of lipocalin-type PGDS in serum and urine.6 The lipocalin-type PGDS has been identified as β-trace (~24 kDa), which is a major protein in the human cerebrospinal fluid.2,7
