Description

This recombinant monoclonal antibody is developed as a research-grade biosimilar to the reference antibody disclosed in US2020317814, targeting ectonucleotide pyrophosphatase/phosphodiesterase 3 (ENPP3). ENPP3 is a cell surface enzyme that hydrolyzes phosphodiester bonds in various nucleotides and exhibits particularly high expression in renal proximal tubular cells and certain epithelial tissues. This protein plays important roles in purinergic signaling and nucleotide metabolism. ENPP3 has emerged as a significant biomarker and therapeutic target in oncology, with overexpression documented in renal cell carcinoma, bladder cancer, and other malignancies where it contributes to tumor progression and metastasis.

The reference antibody described in US2020317814 was designed for specific recognition of ENPP3-expressing cells, making this biosimilar valuable for cancer research applications. This antibody enables investigators to study ENPP3 expression patterns, evaluate its role in tumor biology, and explore targeted therapeutic strategies. The reagent supports research into ENPP3-mediated signaling pathways and its potential as a diagnostic or prognostic marker in various cancers.

Usage

It is a non-therapeutic biosimilar antibody, owning the same variable region from the corresponding approved therapeutic antibody. In conclusion, it is a research-grade biosimilar antibody and expressed in mammalian cell, which can be directly used as positive controls in drug discovery or used for rapid verification of the biological functions of target protein.

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.
