- Herpesviruses are ubiquitous in the human population and they extensively remodel the cellular environment during infection. Multiplexed quantitative proteomic analysis over a whole time-course of herpes simplex virus (HSV)-1 infection was used to characterize changes in the host-cell proteome and to probe the kinetics of viral protein production. Several host-cell proteins were targeted for rapid degradation by HSV-1, including the cellular trafficking factor GOPC. We identify that the poorly-characterized HSV-1 protein pUL56 binds directly to GOPC, stimulating its ubiquitination and proteasomal degradation. Plasma membrane profiling revealed that pUL56 mediates specific changes to the surface proteome of infected cells, including loss of IL18 receptor and Toll-like receptor 2, and delivery of Toll-like receptor 2 to the cell-surface requires GOPC. Our study highlights an unanticipated and efficient mechanism whereby a single virus protein targets a cellular trafficking factor to modify the abundance of multiple signaling molecules at the surface of infected cells. This deposition includes quantified peptide data for the four experiments presented in the manuscript. In HSV_UL56_GOPC_Figures3_and_6.xlsx, 090316_Exp[123] relate to the SILAC IP shown in Figure 3, and Exp1_2018_singleshot_SILAC_LMH_Mock_WT_dUL56" and "Exp2_2018_Fraction[123456]_SILAC_LMH_Mock_WT_dUL56" relate to the plasma membrane profiling experiment shown in Figure 6.
