BANF1
The protein encoded by this gene was first identified by its ability to protect retroviruses from intramolecular integration and therefore promote intermolecular integration into the host cell genome. The protein forms a homodimer which localizes to both the nucleus and cytoplasm and is specifically associated with chromosomes during mitosis. This protein binds to double stranded DNA in a non-specific manner and also binds to LEM-domain containing proteins of the nuclear envelope. This protein is thought to facilitate nuclear reassembly by binding with both DNA and inner nuclear membrane proteins and thereby recruit chromatin to the nuclear periphery. Alternative splicing results in multiple transcript variants encoding the same protein.

Interaction
Homodimer (PubMed:16337940, PubMed:22399800, PubMed:28841419). Heterodimerizes with BANF2 (PubMed:16337940). Interacts with ANKLE2/LEM4, leading to decreased phosphorylation by VRK1 and promoting dephosphorylation by protein phosphatase 2A (PP2A) (PubMed:22770216). Binds non-specifically to double-stranded DNA, and is found as a hexamer or dodecamer upon DNA binding. Binds to LEM domain-containing nuclear proteins such as LEMD3/MAN1, TMPO/LAP2 and EMD (emerin) (PubMed:11792822, PubMed:15681850). Interacts with ANKLE1 (via LEM domain); the interaction may favor BANF1 dimerization (PubMed:22399800). Interacts with CRX and LMNA (lamin-A). Binds linker histone H1.1 and core histones H3 (PubMed:16203725). Interacts with LEMD2 (via LEM domain) (PubMed:32494070). (Microbial infection) Interacts with HIV-1 pre-integration complex in cytoplasm by binding to viral matrix protein and Gag polyprotein.
