The antiretroviral restriction factor TRIM5 has recently emerged as an important mediator of innate immunity and species-specific inhibition of retroviral replication in mammals. Selection pressure from pathogenic infection has driven rapid evolution of TRIM5 genes, leading to the antiviral specificities we see today. Remarkably, the New World owl monkey… (More)
