Tetherin also known as bone marrow stromal antigen 2 is a lipid raft associated protein that in humans is encoded by the BST2 gene. In addition tetherin has been designated as CD317 (cluster of differentiation 317). This protein is constituitively expressed in mature B cells plasma cells and plasmacytoid dendritic cells and in many other cells it is only expressed as a response to a stimuli from IFN pathway.
