**Background of BANF1 Recombinant Protein**
BANF1 (Barrier-to-Autointegration Factor 1) is a highly conserved DNA-binding protein critical for maintaining nuclear architecture and genome stability. It plays essential roles in chromatin organization, nuclear envelope assembly, and mitotic chromosome segregation. BANF1 binds nonspecifically to double-stranded DNA, facilitating chromatin compaction and bridging distant DNA regions. During cell division, it assists in reforming the nuclear envelope by interacting with LEM-domain proteins (e.g., LAP2. emerin) and promoting membrane fusion.
Recombinant BANF1 protein is produced *in vitro* using expression systems like *E. coli* or mammalian cells, enabling functional studies and therapeutic exploration. Structurally, it forms a dimer with two helix-turn-helix motifs, allowing DNA interaction. Its dysfunction is linked to diseases; mutations in BANF1 cause autosomal recessive **Emery-Dreifuss muscular dystrophy (EDMD)**, characterized by muscle wasting and cardiac defects, due to disrupted nuclear envelope integrity. Additionally, BANF1 overexpression is observed in certain cancers, correlating with poor prognosis.
Research applications include investigating nuclear dynamics, chromatin remodeling, and DNA repair mechanisms. In gene therapy, BANF1’s ability to compact DNA is leveraged to enhance viral vector efficiency. Notably, it also serves as a host factor for viral infections, such as HIV-1. where it interacts with viral preintegration complexes. Overall, BANF1 recombinant protein is a vital tool for dissecting nuclear biology and developing targeted therapies.
