Figure 8. SGTA overexpression stabilizes non-glycosylated tetherin in the presence of Vpu.

Figure 8

(A) 293T cells were transfected with the vector expressing HA-tagged tetherin with or without Vpu and FLAG-tagged SGTA expression vectors. 24 h post-transfection, cells were labeled with [35S]Met/Cys for 30 min and then chased for 0, 0.5, 1, 2, or 4 h. Cells were lysed and immunoprecipitated with anti-HA antibodies and analyzed by SDS-PAGE followed by fluorography. Positions of 26-kDa (glycosylated) and 23-kDa (non-glycosylated) tetherin are indicated. (B) the ratio of 23- to 26-kDa tetherin species was calculated from three independent experiments, ± SD. This ratio increased significantly over time in the presence of SGTA and Vpu, p < 0.01.
