Mouse CD39L3/ENTPD3 Biotinylated Antibody

Ectonucleoside triphosphate diphosphohydrolase-3 (NTPDase-3) is an integral membrane protein with an extracellular catalytic domain (1). rhNTPDase-3 was expressed as a protein lacking its N- and C-terminal transmembrane domains, resulting in the secretion of the soluble rhNTPDase-3 ectodomain. NTPDase-3 hydrolyzes the beta- and gamma-phosphate groups of nucleotides, preferring ATP, ADP, UTP, and UDP as substrates (1). Through its hydrolysis of extracellular nuceotides, NTPDase-3 is important for the regulation of purinergic signaling (2). The enzyme is expressed at its highest levels in brain, pancreas, spleen, and prostate tissues (3). In the brain, NTPDase-3 may play a role in the regulation of feeding, sleep, and other behaviors (4).
