**Background of ABCA2 Recombinant Protein**
ABCA2 (ATP-binding cassette subfamily A member 2) is a transmembrane protein belonging to the ABC transporter superfamily, which plays critical roles in cellular lipid transport, membrane homeostasis, and metabolic regulation. Predominantly expressed in the brain, spleen, and myeloid cells, ABCA2 is localized to endosomal and lysosomal compartments, where it is implicated in intracellular lipid trafficking, particularly sphingolipid metabolism. Its dysfunction has been linked to neurodegenerative disorders (e.g., Alzheimer’s disease), cancer drug resistance, and lysosomal storage diseases, highlighting its biomedical relevance.
Recombinant ABCA2 protein is engineered *in vitro* using genetic cloning techniques, often expressed in mammalian or insect cell systems to ensure proper post-translational modifications and functional folding. This engineered protein retains key structural domains, including two transmembrane domains (TMDs) and two nucleotide-binding domains (NBDs), essential for ATP hydrolysis and substrate transport. Researchers utilize ABCA2 recombinant protein to study its molecular mechanisms, ligand interactions, and role in lipid regulation. It also serves as a tool for screening potential therapeutic agents targeting ABCA2-associated pathologies. Despite progress, challenges remain in elucidating its precise substrates and regulatory pathways, driving ongoing research to harness its therapeutic potential in diseases linked to lipid dysregulation.
