1. The primary role of the S(52,56) residues of Vpu in antagonism of CD4, GaLV Env, and BST-2/tetherin is to recruit the SCF/betaTrCP ubiquitin ligase. PMID: 30347660
2. Studied role of bone marrow stromal cell antigen 2 (BST2) in gastric cancer (GC); results show BST2 is overexpressed in GC tissues and BST2 silencing inhibits cell proliferation and migration, partly by regulating NF-kappaB signaling. PMID: 29774441

4. findings support the notion that NAbs can induce ADCC. They highlight that while BST2 antagonism by HIV promotes ADCC evasion, strategies aimed at restoring BST2 restriction could improve anti-HIV responses and potentially provide a means to eliminate reactivated cells in latent reservoirs. PMID: 27853288

10. Coimmunoprecipitation studies indicated that non-glycosylated tetherin is stabilized through the formation of a ternary SGTA/Vpu/tetherin complex. Although the results do not provide support for a physiological function of SGTA in HIV-1 replication, they demonstrate that SGTA overexpression regulates tetherin expression and stability, thus providing insights into the function of SGTA in endoplasmic reticulum translocation PMID: 27103333
11. Importantly, the s demonstrate for the first time that the HIV-2 Env induces NF-kappaB activation in HEKappa293T cells. Furthermore, the anti-BST-2 activity of the HIV-2 Env is not sufficient to completely inhibit NF-kappaB activity. PMID: 29028477

21. The s demonstrated that BST2 restricts the release of Japanese encephalitis virus whose budding occurs at the endoplasmic reticulum-Golgi intermediate compartment, and in turn, Japanese encephalitis virus downregulates BST2 expression via envelope protein E. PMID: 28710958
22. These results suggest that BST2 plays an important role in the progression of renal cell carcinoma (RCC), and, because BST2 is expressed on the cell membrane, BST2 is a good therapeutic target for RCC. PMID: 28551621
23. findings show that BST-2 upregulation by IFN-beta and interleukin-27 (IL-27) also increases the surface expression of Env and thus boosts the ability of CD4mc to sensitize HIV-1-infected cells to ADCC by sera from HIV-1-infected individuals. PMID: 28331088
24. study found that tetherin expression on hematopoietic cells resulted in the specific reduction of Moloney murine leukemia virus cell-free plasma viremia but not the number of infected hematopoietic cells PMID: 28381565
25. The s show that orthobunyaviruses viruses with human tropism (Oropouche virus and La Crosse virus) are restricted by sheep BST-2 but not by the human orthologue, while viruses with ruminant tropism (Schmallenberg virus and others) are restricted by human BST-2 but not by the sheep orthologue. PMID: 28628828
26. Thus, efficient human immunodeficiency virus type 1 release from infected cells seems to play an important role in the spread of the virus in the human population and requires a fully functional Vpu protein that counteracts human tetherin. PMID: 27531907
27. BST-2 restricts influenza A virus release and is countered by the viral M2 protein. PMID: 28087685

34. Studies demonstrate that the interaction Bst-2 and MT1-MMP, actually happens and the cytoplasmic tails, both the N-terminal domain of Bst-2 and the C-terminal domain of MT1-MMP, play crucial roles in the interaction. The interaction between Bst-2 and MT1-MMP is important in MT1-MMP regulating the tetherin activity of Bst-2 and also in Bst-2 regulating the activity of the MT1-MP/proMMP2/MMP2 pathway. PMID: 27240342
35. BST-2 and HIV-2 Env proteins interact through their ectodomain but residues involved are not clearly defined.
