SSBP1 (Single-Stranded DNA Binding Protein 1) is a conserved eukaryotic protein critical for maintaining genome stability and facilitating DNA metabolism. It binds preferentially to single-stranded DNA (ssDNA) with high affinity, a function essential for DNA replication, repair, and recombination. Structurally, SSBP1 forms a homotetramer and contains an oligosaccharide/oligonucleotide-binding (OB) fold domain, which mediates its interaction with ssDNA. This protein is particularly vital in mitochondrial DNA (mtDNA) maintenance, where it coats and stabilizes displaced ssDNA during replication, prevents DNA degradation, and coordinates with enzymes like DNA polymerase γ and helicase TWINKLE.
Recombinant SSBP1 protein, produced through heterologous expression systems (e.g., *E. coli* or mammalian cells), serves as a key tool for studying DNA-protein interactions *in vitro*. Its applications span structural studies (e.g., crystallography), biochemical assays (e.g., electrophoretic mobility shift assays), and functional analyses of mitochondrial disorders. Mutations in the *SSBP1* gene are linked to human diseases such as autosomal dominant optic atrophy (ADOA) and mtDNA depletion syndromes, underscoring its role in cellular health. Recombinant SSBP1 enables researchers to dissect pathogenic mechanisms, screen potential therapeutics, and explore its interplay with other replication machinery components. Additionally, it aids in understanding nuclear DNA processes, including replication fork protection and telomere maintenance. The development of recombinant SSBP1 has significantly advanced both basic research and translational studies in genetics and molecular medicine.
