The presence of HSV-1 miR-LAT-ICP34.5 indicates that miRNAs encoded by HSV-1 and HSV-2 LATs are evolutionarily conserved in their locations rather than in their sequences, implying that the mechanism by which LAT functions in trans as miRNAs in regulating ICP34.5 expression is shared in HSV-1 and HSV-2.
An overview of known targets of cellular or viral targets is given in tables 2 and 3.Table 2 Cellular Targets of viral miRNAs.Table 3 Viral Targets of viral miRNAs.
