    A, Ancestral state sequence reconstruction upstream of the Eptesicus fuscus- CaaX prenylation motif. C-terminal end of the protein alignment of the 10 bat GBP5s tested in functional assays (asterisk, stop codon). Phylogenetic tree was used to infer the ancestral sequence of the C-terminal region, the branch where the prenylation motif was lost by a premature stop codon is annotated on the tree. The site of mutagenesis for reconstruction is indicated by the blue arrow. B, Reconstruction of the C-ter relocalizes Eptesicus fuscus GBP5-CaaX to the trans- Golgi network (TGN). Briefly, TZM-bl cells were transfected with plasmids encoding HA-GBP5s and, 48 hour later, were analyzed by confocal fluorescence microscopy. GBP5, nuclei and TGN were stained with anti-HA, DAPI and anti-TGN46 antibodies, respectively. Scale bar indicates 15 μm. C, GBP5 mean intensity at the Golgi vs. the total cell was quantified for the wild-type eptFus and the mutant eptFus-CaaX . Each dot corresponds to one cell. Two independent replicates are identified by different dot colors. D, Pearson coefficient correlation per cell calculated between GBP5 and TGN signals for the wild-type eptFus and the mutant eptFus-CaaX. Data are represented as a mean ± SD. Statistics vs. the corresponding control condition, Nested t test: **, p -value < 0.01 ( n = 2). E–G, Ancestral reconstruction of the prenylation CaaX did not increase Eptesicus fuscus GBP5 restriction of intrinsic viral infectivity.

Phylogenetic tree was used to infer the ancestral sequence of the C-terminal region, the branch where the prenylation motif was lost by a premature stop codon is annotated on the tree. The site of mutagenesis for reconstruction is indicated by the blue arrow. B, Reconstruction of the C-ter relocalizes Eptesicus fuscus GBP5-CaaX to the trans- Golgi network (TGN). Briefly, TZM-bl cells were transfected with plasmids encoding HA-GBP5s and, 48 hour later, were analyzed by confocal fluorescence microscopy. GBP5, nuclei and TGN were stained with anti-HA, DAPI and anti-TGN46 antibodies, respectively. Scale bar indicates 15 μm. C, GBP5 mean intensity at the Golgi vs. the total cell was quantified for the wild-type eptFus and the mutant eptFus-CaaX . Each dot corresponds to one cell. Two independent replicates are identified by different dot colors. D, Pearson coefficient correlation per cell calculated between GBP5 and TGN signals for the wild-type eptFus and the mutant eptFus-CaaX. Data are represented as a mean ± SD. Statistics vs. the corresponding control condition, Nested t test: **, p -value < 0.01 ( n = 2). E–G, Ancestral reconstruction of the prenylation CaaX did not increase Eptesicus fuscus GBP5 restriction of intrinsic viral infectivity. E, Infectivity of RT-normalized HIV-1 pseudotyped-viruses in the presence of GBP5, normalized to the condition without GBP5 (EV control) at 100%. Dose of GBP5 plasmids: 1, 2, and 4 µg with constant total DNA transfected across conditions. Experimental setup as in . RLU, Relative light units. Viral titers (RT activity) are shown in . F, Corresponding western blot showing the expression of HA-GBP5, HIV-1 Env and Gag in the viral producer Tzm-bl cells with beta-actin as loading control (kDa, on the right). Quantification of three independent experiments is shown in . G, Intrinsic infectivity of (RT-normalized) VSVg or EBLV-1g pseudotyped retroviruses in the presence of GBP5s, normalized to EV control at 100%.
