Viral protein involved in the modulation of host dendritic cell activity. Dendritic cells operate at the interface between the innate and adaptive immune response by their ability to sample their environment for pathogenic products, to process them, and to present viral antigens to T-cells. This results in T cell proliferation and the induction of virus-specific adaptive immune responses. Therefore impairing dendritic cell function by viruses is an effective strategy to disrupt the host immune response.
