Red List (low evidence)

Evidence Summary from Illumina curation team: BANF1 is an abundant, highly conserved DNA binding protein involved in multiple pathways including mitosis, nuclear assembly, viral infection, chromatin and gene regulation and the DNA damage response. It is also essential for early development in metazoans and relevant to human physiology. Variants in the gene are associated with Nestor-Guillermo progeria syndrome (OMIM #614008). Different viral infections can lead to changes in the subcellular distribution of BANF1 infections with a B1 kinase-deficient vaccinia virus cause re-localization at sites of viral DNA accumulation in the cytoplasm, while no change in localization is found during infection with wild-type vaccinia. By contrast, in cells infected with Herpes Simplex Virus Type-1 (HSV-1) BAF localizes to the nucleus, where HSV-1 viral DNA replicates. BANF1 actively protects the genome by intercepting foreign DNA. This protective function is exploited by retroviruses for inhibiting self-destructing autointegration of retroviral DNA, thereby promoting integration of viral DNA into the host chromosome. However, with other viruses, including the poxvirus vaccinia and HSV-1, BANF1 has an antiviral activity by blocking viral DNA replication (PMID 2607214: Jamin et al. 2015).
