**Background of Recombinant RBP1 Protein**
Recombinant Retinol-Binding Protein 1 (RBP1) is a engineered version of the endogenous RBP1. a key carrier protein involved in the transport and metabolism of vitamin A (retinol) within the body. Naturally, RBP1 is synthesized primarily in the liver and plays a critical role in binding and solubilizing hydrophobic retinol, facilitating its delivery to target tissues such as the retina, where it supports vision, and epithelial cells, which rely on vitamin A for differentiation and function. RBP1 also interacts with transthyretin (TTR) in circulation, forming a complex that prevents renal filtration and stabilizes retinol during transport.
The recombinant form of RBP1 is produced using biotechnological platforms, such as *E. coli* or mammalian cell expression systems, to ensure high purity and bioactivity. By cloning the *RBP1* gene into expression vectors, researchers can produce large quantities of the protein for functional studies. Recombinant RBP1 retains the ability to bind retinol and interact with TTR, making it invaluable for investigating vitamin A metabolism, cellular signaling pathways, and diseases linked to retinoid dysregulation, such as age-related macular degeneration, cancer, and metabolic disorders.
Additionally, recombinant RBP1 serves as a tool in drug discovery, enabling the screening of compounds that modulate retinol delivery or disrupt RBP1-receptor interactions. Its role in maintaining retinoid homeostasis has also spurred interest in therapeutic applications, including targeted delivery systems for vitamin A-based therapies. Overall, recombinant RBP1 bridges fundamental research and clinical innovation, offering insights into retinoid biology and potential treatments for related pathologies.
