CD73/5'-Nucleotidase Protein, Cynomolgus (521a.a, HEK293, His)

CD73/5'-Nucleotidase Protein, Cynomolgus (HEK 293, His) is a CD73 protein with a His-flag. CD73/5'-Nucleotidase Protein a zinc-dependent, 70 kDa homodimeric enzyme that binds to the cell membrane through a glycosyl phophatidylinositol (GPI) anchor^[1].

CD73/5'-Nucleotidase is a zinc-dependent, 70 kDa homodimeric enzyme bound to the cell membrane through a glycosyl phophatidylinositol (GPI) anchor
. Vertebrate ecto-5'-nucleotidase (eN, EC 3.1.3.5) hydrolyzes ribo- and deoxyribonucleoside 5′-monophosphates including AMP, CMP, UMP, IMP, and GMP, whereby AMP generally is the most effectively hydrolyzed nucleotide
. CD73 is thought to function as a co-signaling molecule on T lymphocytes and an adhesion molecule that is required for lymphocyte binding to endothelium^[1].^[2]
