Fig. 6From: Mutagenesis of N-terminal residues of feline foamy virus Gag reveals entirely distinct functions during capsid formation, particle assembly, Gag processing and buddingSubcellular localization of wt and single-mutant FFV Gag proteins. HeLa cells were transfected with proviral pCF-7-based Gag mutants (R32A, G36A, G39A and R43A) and the parental provirus pCF-7. pcDNA plasmid was used for transfection as negative control. At 36 h p.t., cells were fixed and stained with a rabbit polyclonal antiserum generated against FFV Gag and Alexa-488-conjugated secondary antibody. Nuclei were stained with DAPI.
