Description

This Human ENPP3 recombinant protein was produced in mammalian cell, where the gene sequence encoding human ENPP3 (48-875aa) was expressed with the C-terminal 10xHis tag. The purity of this ENPP3 protein was greater than 95% by SDS-PAGE. The activity was validated.

ENPP3 (Ectonucleotide pyrophosphatase/phosphodiesterase family member 3) is a type II transmembrane protein, which is involved in the hydrolysis of extracellular nucleotides and has ATPase and ATP pyrophosphatase activities. ENPP3 was originally identified as a regulator of purinergic signaling with a role in inflammation and allergic responses, while ENPP3 protein could serve as a potential biomarker of allergen sensitivity. ENPP3 is mainly present on epithelial and mucosal surfaces and is highly expressed on activated basophils. ENPP3 has been detected in mastocytosis, acute basophilic leukemia, tumor mast cells of cholangiomas, and some other cancer samples. ENPP3 is a multifunctional extracellular nucleotide hydrolase whose main function is to metabolize extracellular nucleotides, including ATP, GTP, UTP and CTP.

Target Background

Function

Hydrolase that metabolizes extracellular nucleotides, including ATP, GTP, UTP and CTP. Limits mast cell and basophil responses during inflammation and during the chronic phases of allergic responses by eliminating the extracellular ATP that functions as signaling molecule and activates basophils and mast cells and induces the release of inflammatory cytokines. Metabolizes extracellular ATP in the lumen of the small intestine, and thereby prevents ATP-induced apoptosis of intestinal plasmacytoid dendritic cells. Has also alkaline phosphodiesterase activity.
