SUBCELLULAR LOCALIZATION	intracellular

	intracellular,nucleus

basic FUNCTION	glutathione-independent prostaglandin D synthase that catalyzes the conversion of prostaglandin H2 (PGH2) to postaglandin D2 (PGD2)
	involved in the regulation of non-rapid eye movement sleep
	newly identified melanocyte marker
	play important roles in both maturation and maintenance of the central nervous system and male reproductive system
	PTGDS and its receptor chemoattractant receptor homologous molecule expressed on T(h)2 cells (GPR44) have been implicated in the pathogenesis of numerous allergic diseases
	new regulator of tumor vascular permeability
	in addition to promoting the recruitment and activation of Th2 cells, may also impede the resolution of allergic inflammation through inhibiting apoptosis of Th2 cells
	beneficial for protecting the brain against transient and permanent cerebral ischemia
	catalyses the formation of prostaglandin D(2) (PGD(2)) and also functions as a transporter for lipophilic ligands, including all-trans retinoic acid (RA)
	lipocalin-type enzyme involved in the metabolism of arachidonic acid and plays a key role in the regulation of sleep, allergy, pain sensation, and the development of male reproductive organs
