– Ectonucleotide pyrophosphatase-phosphodiesterase 3 (ENPP3), a protein detected in the human uterus, has been found to play an important role in the development and invasion of tumours. It was recently discovered that ENPP3 was upregulated during the window of implantation in the human endometrium but its functional relevance remains elusive. ENPP3 Protein, Human, Recombinant (aa 48-157, His & Avi) is expressed in HEK293 mammalian cells with N-His-Avi tag. The predicted molecular weight is 17.21 kDa and the accession number is O14638.
