RPS3 and infection: In infected cells, UL47 phosphorylation was also detected in Chinese virulent strain (CHv) infection but not in ΔUS3, and lack of US3 protein caused a delay of UL47 translocation to the cytoplasm, suggesting that US3 is important for the cytoplasmic localization of UL47 during DPV infection, with further understanding of the functions of US3 in DPV.
