Activity summary

The ENPP3/B10 protein also known as Ectonucleotide Pyrophosphatase/Phosphodiesterase 3 is an enzyme that plays a role in nucleotide metabolism by hydrolyzing phosphodiester and phosphosulfate bonds. This protein has a molecular mass of around 100 kDa. ENPP3 is mainly expressed on the surface of epithelial cells and you find it in tissues like the kidney liver and lung. In some contexts immune cells such as mast cells also show its expression.

Biological function summary

ENPP3 regulates the availability of extracellular nucleotides and phosphate metabolites. It is not typically considered part of a larger complex and rather contributes to various processes independently. By modulating concentrations of these extracellular molecules ENPP3 impacts cell signaling and nucleotide homeostasis which can affect cell proliferation and differentiation.

Pathways

This enzyme engages in the purinergic signaling pathway and can influence the MAPK/ERK pathway. Through its enzymatic action on nucleotides ENPP3 helps regulate signaling molecules which participate in processes such as cell growth and immune responses. Proteins related to these pathways include ATP-binding proteins like P2Y receptors and kinases involved in MAPK/ERK signaling.

Associated diseases and disorders

ENPP3's function links it to conditions such as allergy and asthma as its expression on mast cells affects histamine release. Changes in its activity are also noted in certain cancers where its role in signaling pathways can contribute to uncontrolled cell proliferation. In these disease contexts the protein interacts with other signaling molecules like cytokine receptors and oncogenic proteins which can modulate or exacerbate disease progression.
