DNAM-1/CD226 Fc Chimera, Human - 10μg

DNAM-1 (DNAX accessory molecule-1), also known as CD226, platelet and T cell activation antigen 1 (PTA1) and TLiSA1, is a member of the Ig superfamily containing two Ig-like domains of the V set and is encoded by a gene on human chromosome 18q22.3. DNAM-1 is an activating receptor expressed on natural killer (NK) cells, CD8+ T cells, and other immune cells. Upon recognition of its ligands, CD155 and CD112, DNAM-1 promotes NK cell–mediated elimination of transformed and virus-infected cells. It also has a key role in expansion and maintenance of virus-specific memory NK cells. DNAM-1 is the cell surface receptor of NECTIN2. Upon ligand binding, it stimulates T cell proliferation and cytokine production, including that of IL2, IL5, IL10, IL13 and IFNG.
