Adenosine deaminase

UniProtKB accession:  P03958

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the hydrolytic deamination of adenosine and 2-deoxyadenosine (PubMed:10720488, PubMed:8634299, PubMed:8672487, PubMed:8942668, PubMed:9272950). Plays an important role in purine metabolism and in adenosine homeostasis (PubMed:10720488, PubMed:9272950). Modulates signaling by extracellular adenosine, and so contributes indirectly to cellular signaling events (PubMed:11435465). Acts as a positive regulator of T-cell coactivation, by binding DPP4. Its interaction with DPP4 regulates lymphocyte-epithelial cell adhesion (By similarity). Enhances dendritic cell immunogenicity by affecting dendritic cell costimulatory molecule expression and cytokines and chemokines secretion (By similarity). Enhances CD4+ T-cell differentiation and proliferation (By similarity). Acts as a positive modulator of adenosine receptors ADORA1 and ADORA2A, by enhancing their ligand affinity via conformational change (By similarity). Stimulates plasminogen activation (By similarity). Plays a role in male fertility (By similarity). Plays a protective role in early postimplantation embryonic development (PubMed:9272950). Also responsible for the deamination of cordycepin (3'-deoxyadenosine), a fungal natural product that shows antitumor, antibacterial, antifungal, antivirus, and immune regulation properties (PubMed:26038697).
