NCR3LG1 (Natural Cytotoxicity Triggering Receptor 3 Ligand 1), also known as B7-H6. is a cell surface protein belonging to the B7 family of immune regulatory molecules. It was first identified in 2009 as a ligand for the activating natural killer (NK) cell receptor NKp30 (NCR3), playing a critical role in NK cell-mediated immune responses. Structurally, NCR3LG1 is a type I transmembrane protein composed of an extracellular IgV-like domain, a transmembrane region, and a short cytoplasmic tail. Its expression is tightly regulated and primarily induced under pathological conditions, such as inflammation, infection, or cancer.
In normal tissues, NCR3LG1 is scarcely expressed but becomes upregulated on the surface of stressed, infected, or malignant cells. This upregulation enables NK cells to recognize and eliminate abnormal cells through NKp30 binding, triggering cytotoxic granule release and cytokine production. However, some tumors exploit NCR3LG1 overexpression to promote immune evasion by inducing NKp30 internalization and NK cell dysfunction, highlighting its dual role in immunity.
Recombinant NCR3LG1 protein is engineered to study these interactions, typically produced in mammalian expression systems to ensure proper glycosylation and functionality. Researchers use it to investigate NK cell activation mechanisms, tumor immune escape strategies, and potential therapeutic applications. In immunotherapy development, recombinant NCR3LG1 serves as a tool for enhancing NK cell cytotoxicity or designing blocking agents to counteract its immunosuppressive effects in cancers. Its role in viral infections (e.g., HIV, CMV) and autoimmune diseases is also under exploration, making it a versatile target in immunology research.
