Intrinsic defenses targeting foreign DNA are one facet of the cellular armament tasked with protecting host genomic integrity. The DNA binding protein BAF (barrier to autointegration factor) contributes to multiple aspects of genome maintenance and intercepts retrovirus, poxvirus, and herpesvirus genomes during infection. In this gem, we discuss the unique position BAF occupies at the virus-host interface and how both viral and cellular mechanisms may regulate its capacity to act as a pro- or antiviral effector targeting viral DNA.
