SARS-CoV
TIM genes are also involved in host-virus interaction. As receptors for phosphatidylserine, TIM proteins bind many families of viruses [filovirus, flavivirus, New World arenavirus and alphavirus] that include viruses such as dengue and ebola. Entry of Lassa fever virus, influenza A virus, and SARS coronavirus were not affected by TIM-1 expression. TIM-1 and TIM-4 enhanced viral entry more than TIM-3.
