Check out the top hotspot genes for each virus.
Viruses may intrude human cellular system and even insert their genetic material into the host genome, thus affecting the normal function of the molecules in the host cells.It is of great significance to construct a knowledgebase of virus integration site(VIS) and to curate site-related information to facilitate those work on virus related pathology, virus biology, host-pathogen interaction, sequence motif discovery/pattern recognition, molecular evolution and adaption, disease study, among others.
