Ectonucleoside triphosphate diphosphohydrolase 1 (CD39)

Target
CD39
Molecular classification
Enzyme, Ectonucleotidase
01

Overview

Ectonucleoside triphosphate diphosphohydrolase 1 (CD39) is a cell surface enzyme that hydrolyzes extracellular ATP and ADP to AMP. It plays a crucial role in regulating purinergic signaling, inhibiting platelet aggregation, and modulating inflammation and fibrosis, particularly in the cardiovascular system.

Other names
ENTPD1NTPDase-1ATPDaseSPG64
02

Mechanism of action

Hydrolyzes γ- and β-phosphate residues of nucleoside tri- and diphosphates (e.g., ATP, ADP, UTP, UDP) to their corresponding monophosphates (e.g., AMP).
