FIG. 5.

Surface distribution of mutant F and G proteins. (A) Amino acid sequences of the cytoplasmic domains of wild-type and mutant F and G proteins. Numbers above the sequences indicate amino acid positions. Boldface letters indicate exchanged amino acid residues. Vertical lines indicate the beginning of the predicted transmembrane domains. (B and C) Surface distribution of mutant NiV glycoproteins. MDCK cells stably expressing either wild-type or mutant NiV F (B) or G (C) proteins were immunostained as described in the legend to Fig. 4. Vertical sections through the cell monolayers are shown. Bar, 10 μm.
