<unk>  is a human cellular protein which inhibits retrovirus infection by preventing the diffusion of virus particles after budding from infected cells. Initially discovered as an inhibitor to HIV-1 infection in the absence of Vpu,<unk>  has also been shown to inhibit the release of other RNA viruses such as the Lassa and Marburg virions suggesting a common mechanism that inhibits enveloped virus release without interaction with viral proteins. In addition,<unk>  also restricts neuroinvasion of the DNA virus HSV-1. However, in contrast to its anti-viral role, it has recently been shown that basal levels of BST2 or<unk>  are required for HIV-1 replication but this isn't an indication that higher than basal levels of BST2 promotes viral replication. More definite research is required.
