Barrier to autointegration factor 1
Lua error in Module:Infobox_gene at line 33: attempt to index field 'wikibase' (a nil value). Barrier-to-autointegration factor is a protein that in humans is encoded by the BANF1 gene.[1][2] It is a member of the barrier-to-autointegration factor family of proteins.
Function
The protein encoded by this gene was identified by its ability to protect retroviruses from intramolecular integration and therefore promote intermolecular integration into the host cell genome. The endogenous function of the protein is unknown. The protein forms a homodimer which localizes to the nucleus and is specifically associated with chromosomes during mitosis. This protein binds to DNA in a non-specific manner and studies in rodents suggest that it also binds to lamina-associated polypeptide 2, a component of the nuclear lamina.[2] It also associates with the LEM Domain containing proteins LAP2, Emerin, and MAN1.
Interactions
Barrier to autointegration factor 1 has been shown to interact with Thymopoietin.[3]
Clinical relevance
Mutations in this gene have been shown to cause hereditary progeroid syndrome.[4]
