Changes in the serine incorporator 5 (SERINC5)-induced non-glycosylation of hepatitis B virus (HBV) LHB, MHB, and SHB proteins were similar to the pattern of glycan mutants. (A) HEK293T cells were co-transfected with LHBs-flag, MHBs-flag, or SHBs-flag proteins or the indicated glycan mutants plus a negative control vector VR1012 or the SERINC5-HA. Immunoblot analysis of SERINC5 and LHB, MHB, SHB, expression using anti-HA or anti-flag antibodies. (B) SERINC5 had a similar effect on HBV LHB, MHB, and SHB proteins (C) but not BST-2 with tunicamycin. HEK293T cells were co-transfected as indicated. Twelve hours prior to cell harvest, the cells were treated with 10 μg/ml tunicamycin. Immunoblot analysis of SERINC5, LHB, MHB, SHB, and BST-2 expression. Tubulin served as a loading control.
