Ectonucleoside triphosphate diphosphohydrolase 3 is an enzyme that in humans is encoded by the ENTPD3 gene.ENTPD3 is similar to E-type nucleotidases (NTPases). NTPases such as CD39 mediate catabolism of extracellular nucleotides. ENTPD3 contains 4 apyrase-conserved regions which is characteristic of NTPases.
