Product Description

The C39Mab-1 monoclonal antibody reacts with mouse CD39, also known as ectonucleoside triphosphate diphosphohydrolase 1 (Entpd1), NTPDase-1, ATP-DPH, and Ecto-ATPase 1. The major function of CD39 is to hydrolyze extracellular adenosine triphosphate (eATP) to diphosphate (eADP) and adenosine monophosphate (AMP). 5’-nucleotidase (NT5E/CD73) dephosphorylates AMP to generate adenosine, which mediates an immunosuppressive tumor microenvironment in tumors. CD39 acts as an "immunological switch" by regulating the balance between immunostimulatory or pro-inflammatory eATP and immunosuppressive adenosine nucleotides, thereby controlling inflammation and immune responses. This function is critical in various processes, including immune cell regulation, anti-tumor immunity, and vascular inflammation. In various tumors, an increased expression of CD39 is shown to promote the local accumulation of adenosine surrounding tumors. Anti-CD39 monoclonal antibodies, as monotherapy or in combination with other targets, e.g., PD-1 blockade, for modulating the adenosine metabolism, are emerging as a promising immunotherapy strategy in cancer research.

A cell-surface ectonucleotidase CD39 mediates the conversion of extracellular adenosine triphosphate into immunosuppressive adenosine with another ectonucleotidase CD73. The elevated adenosine in the tumor microenvironment attenuates antitumor immunity, which promotes tumor cell immunologic escape and progression. Anti-CD39 monoclonal antibodies (mAbs), which suppress the enzymatic activity, can be applied to antitumor therapy. Therefore, an understanding of the relationship between the inhibitory activity and epitope of mAbs is important. We previously established an anti-mouse CD39 (anti-mCD39) mAb, C39Mab-1 using the Cell-Based Immunization and Screening method. In this study, we determined the critical epitope of C39Mab-1 using flow cytometry. We performed the PA tag (12 amino acids [aa])-substituted analysis (named PA scanning) and RIEDL tag (5 aa)-substituted analysis (named RIEDL scanning) to determine the critical epitope of C39Mab-1 using flow cytometry. By the combination of PA scanning and RIEDL scanning, we identified the conformational epitope, spanning three segments of 275-279, 282-291, and 306-323 aa of mCD39. These analyses would contribute to the identification of the conformational epitope of membrane proteins.
