Cytoplasmic expression of mutant gI protein gI-S343A transfected with the plasmid PTM1-gI-S343A. This mutant has a Serine changed to an Alanine at amino acid 343 which lies in a major phosphorylation site. Each of the mutants showed similar cellular distubution as wild type gI. Other experiments showed that the phosphorylation of the mutant gI was signifigantly lowered.
