== Function ==
 +
[https://www.uniprot.org/uniprot/PTGDS_MOUSE PTGDS_MOUSE] Catalyzes the conversion of PGH2 to PGD2, a prostaglandin involved in smooth muscle contraction/relaxation and a potent inhibitor of platelet aggregation. Involved in a variety of CNS functions, such as sedation, NREM sleep and PGE2-induced allodynia, and may have an anti-apoptotic role in oligodendrocytes. Binds small non-substrate lipophilic molecules, including biliverdin, bilirubin, retinal, retinoic acid and thyroid hormone, and may act as a scavenger for harmful hydrophopic molecules and as a secretory retinoid and thyroid hormone transporter. Possibly involved in development and maintenance of the blood-brain, blood-retina, blood-aqueous humor and blood-testis barrier. It is likely to play important roles in both maturation and maintenance of the central nervous system and male reproductive system.<ref>PMID:8922532</ref> <ref>PMID:9892701</ref> <ref>PMID:10781097</ref> <ref>PMID:11751991</ref> <ref>PMID:12077186</ref> <ref>PMID:17715133</ref> <ref>PMID:19546224</ref> <ref>PMID:19833210</ref>

== Publication Abstract from PubMed ==
 +
Lipocalin-type prostaglandin D synthase (L-PGDS) acts as both a PGD(2) synthase and an extracellular transporter for small lipophilic molecules. From a series of biochemical studies, it has been found that L-PGDS has an ability to bind a variety of lipophilic ligands such as biliverdin, bilirubin and retinoids in vitro. Therefore, we considered that it is necessary to clarify the molecular structure of L-PGDS upon binding ligand in order to understand the physiological relevance of L-PGDS as a transporter protein. We investigated a molecular structure of L-PGDS/biliverdin complex by small-angle X-ray scattering (SAXS) and multi-dimensional NMR measurements, and characterized the binding mechanism in detail. SAXS measurements revealed that L-PGDS has a globular shape and becomes compact by 1.3A in radius of gyration on binding biliverdin. NMR experiments revealed that L-PGDS possessed an eight-stranded antiparallel beta-barrel forming a central cavity. Upon the titration with biliverdin, some cross-peaks for residues surrounding the cavity and EF-loop and H2-helix above the beta-barrel shifted, and the intensity of other cross-peaks decreased with signal broadenings in (1)H-(15)N heteronuclear single quantum coherence spectra. These results demonstrate that L-PGDS holds biliverdin within the beta-barrel, and the conformation of the loop regions above the beta-barrel changes upon binding biliverdin. Through such a conformational change, the whole molecule of L-PGDS becomes compact.
