CD203c is a 120-130 kDa type II transmembrane glycoprotein that belongs to the ectonucleotidase family, AP superfamily of enzymes. CD203c is also known as ectonucleotide pyrophosphatase/phosphodiesterase 3 (ENPP-3) and it modulates purinergic signaling by hydrolysis of nucleotide di- and tri-phosphates plus sphingosylphosphorylenosine. Although CD203c is considered to be a marker for activated basophils and mast cells, it is also found constitutively or inducibly on bile duct epithelium, hepatocytes, duodenal columnar epithelium, osteoblasts, plasmacytoid dendritic cells, airway pseudostratified ciliated columnar epithelium and renal proximal tubule S3 segment cells. Within the ECD, human CD203c shares 81% aa sequence identity with mouse and rat CD203.
