DcR3 (human):Fc (human) (rec.)

The extracellular domain of human DcR3 (aa 24-300) is fused to the N-terminus of the Fc region of human IgG1. DcR3 protein function: Decoy receptor that can neutralize the cytotoxic ligands TNFS14/LIGHT, TNFSF15 and TNFSF6/FASL. Protects against apoptosis. [The UniProt Consortium] Decoy receptor 3 (DcR3, TNFRSF6B, M68) is a member of the TNF receptor superfamily. DcR3 shares sequence identity with OPG (31%), TNF-RII (29%) and Fas (17%) and is expressed in a variety of different tissues and at high levels in many malignant tumors. Ligands of DcR3 include Fas ligand, homologous to lymphotoxin showing inducible expression and competing with HSV glycoprotein D for herpes virus entry mediator (a receptor expressed by T lymphocytes), TNF-like molecule 1A and heparan sulfate proteoglycans. DcR3 modulates the function of T cells, dendritic cells and macrophages. DcR3/Fc fusion proteins can bind to human and mouse B cells and suppress the activation of B cells.
