CD39 contributes to immune regulation through the hydrolysis of ATP to AMP in the rate limiting step of extracellular adenosine production. CD39 is expressed on the surface of multiple cells of the immune system including T-cells, Natural killer cells, B-cells, dendritic cells and macrophages. In addition, high levels of CD39 expression have been associated with the tumor microenvironment (TME). Research aimed at reducing immunosuppression by CD39 activity has resulted in the study of a small molecule inhibitor, POM1, and multiple anti-CD39 antibodies selected for blocking enzymatic activity or decreasing CD39 expression. 


Human CD73 protein, also known as 5'- nucleotidase and Ecto-5'-nucleotidase, GenBank Accession No. NM_002526, a.a. 27-547 with C-terminal His-tag, expressed in a HEK293 cell expression system. MW = 58.6 kDa. This protein runs at a higher MW by SDS-PAGE due to glycosylation.
