FIG. 2.
F2-C68 and F1-C195 residues are required for F processing. Biotinylated F protein displayed at the cell surface (SF) and total cell lysates (TL) were detected by Western blot analysis using antibodies directed against the F cytosolic tail. As a control (Co), biotinylation of cells transfected with equal amounts of F-Edm was omitted.
