UniProtKB description:  Factor of infectivity and pathogenicity, required for optimal virus replication. Alters numerous pathways of T-lymphocyte function and down-regulates immunity surface molecules in order to evade host defense and increase viral infectivity. Alters the functionality of other immunity cells, like dendritic cells, monocytes/macrophages and NK cells. One of the earliest and most abundantly expressed viral proteins (By similarity).
