NCIt definition : Ectonucleotide pyrophosphatase/phosphodiesterase family member 1 (925 aa, 105 kDa)
is encoded by the human ENPP1 gene. This protein plays a role in the cleavage of phosphodiester
bonds of nucleotides and nucleotide sugars and pyrophosphate bonds of nucleotides
and nucleotide sugars.;
NCIt note : A secreted form of ectonucleotide pyrophosphatase/phosphodiesterase family member
1 is produced intracellularly by cleavage at Lys-103. The secreted form has the following
activities: alkaline phosphodiesterase I (EC:3.1.4.11) and nucleotide pyrophosphatase
(EC:3.6.1.91; NPPase; nucleotide diphosphatase). (UniProt);
