BST-2 (bone marrow stromal antigen 2), also known as tetherin or CD317. is a host restriction factor that plays a critical role in innate immunity by inhibiting the release of enveloped viruses from infected cells. Discovered in 2008. BST-2 is a type I transmembrane protein with a unique topology: it features an N-terminal transmembrane domain, an extracellular coiled-coil domain, and a C-terminal glycosylphosphatidylinositol (GPI) anchor. This dimeric structure enables BST-2 to physically "tether" budding viral particles to the cell membrane, preventing their dissemination and promoting their degradation. Its antiviral activity has been extensively studied against HIV-1. Ebola, and other viruses, which often encode antagonists (e.g., HIV-1 Vpu) to counteract BST-2.
Beyond virology, BST-2 is expressed in various tissues and implicated in cancer progression, autoimmune diseases, and immune regulation. Overexpression of BST-2 has been observed in multiple cancers, including breast cancer and myeloma, where it may influence cell adhesion, signaling, and drug resistance. In autoimmune contexts, BST-2 modulates plasmacytoid dendritic cell functions and type I interferon production. Antibodies targeting BST-2 are essential tools for research, enabling the study of its expression, localization, and interaction with viral proteins. Therapeutic applications are also being explored, such as blocking BST-2 to enhance antiviral immunity or targeting it in cancer immunotherapy. However, its dual roles in viral restriction and pathological processes necessitate careful evaluation in clinical contexts.
