Background Information
BST2, also named as CD317 and Tetherin, belongs to the tetherin family. It may be involved in the sorting of secreted proteins and it is involved in pre-B-cell growth. BST2 is an antiretroviral defense protein, that blocks retrovirus release from the cell surface. Depleted upon HIV-1 infection by viral VPU protein through 20S proteasome degradation. Depleted upon infection by human Kaposi's sarcoma-associated herpesvirus (KSHV) through ubiquitination and subsequent degradation. BST2 may play a role in B-cell activation in rheumatoid arthritis. It is recently identified interferon-induced cellular proteins that restrict infections by retroviruses and filoviruses and of influenza virus and flaviviruses, respectively. BST2 is a plasma membrane protein, tetherin inhibits virion particle release from infected cells. BST2 is effective against retroviruses and flavoviruses whilst IFITMs disrupt influenza and flavivirus infection. Observed MW of BST2 are 30-36 kDa (monomer form) and 50-70 kDa (dimer form) (PMID: 19196977; 21237475; 19737401; 37922253).

Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
FH Sen (Verified Customer) (04-16-2025) | The BST-2 protein could not be detected when I do the dry transfer, I don't know why. However, when I do the classic transfer with 20% of ethanol, it works.
 |
FH Margaux (Verified Customer) (06-13-2024) | Very good efficiency. In HeLa cells, I detected BST2 dimers and monomers at the dilution 1/1000.
 |
FH Christine (Verified Customer) (10-08-2021) | Detects endogenous BST2 in HeLa cells (BST2 positive), also when overexpressed as FLAG tagged version in HeLa cells. Does no detect anything in HEK293T cells (BST2 negative) but detects many bands when FLAG BST2 or untagged BST2 is overexpressed in these cells.
