NPP3 (CD203c, ENPP3) is a member of the human NPP family. NPP3 is expressed in multiple organs, including on epithelial and mucosal surfaces, and notably on basophils and mast cells. This protein is in fact a common marker for diagnosing allergen sensitivity with patient basophils by flow cytometry. Basophils and mast cells mediate the response to certain pathogens, as well as acute and chronic allergic reactions. Following activation, these cells release ATP, which further stimulates them in an autocrine manner. NPP3 upregulation serves to degrade ATP and suppress chronic allergic inflammation (but not the acute response).
