背景信息

**Background on FBN1 Recombinant Protein**

FBN1 (fibrillin-1) is a large extracellular matrix glycoprotein encoded by the *FBN1* gene, primarily known for its critical role in forming microfibrils—elastic structures essential for connective tissue integrity. These microfibrils provide structural support to tissues and regulate signaling pathways, particularly those involving transforming growth factor-beta (TGF-β). Mutations in *FBN1* are linked to Marfan syndrome, a genetic disorder affecting the cardiovascular, ocular, and skeletal systems.

Recombinant FBN1 protein is produced using biotechnological methods, such as expression in mammalian cell systems (e.g., HEK293 or CHO cells), to ensure proper post-translational modifications like glycosylation and disulfide bond formation. The process involves cloning the *FBN1* cDNA into expression vectors, followed by purification via affinity chromatography. Challenges in production include the protein’s large size (~350 kDa) and complex domain structure, requiring optimized conditions for solubility and stability.

Research applications of recombinant FBN1 include studying its interactions with extracellular matrix components (e.g., integrins, elastin) and elucidating pathogenic mechanisms in Marfan syndrome. It also serves as a tool to investigate TGF-β dysregulation and test therapeutic strategies, such as angiotensin receptor blockers, which may mitigate aortic complications. In tissue engineering, FBN1 recombinant protein is explored for developing biomimetic scaffolds to enhance cell adhesion and tissue repair.

Despite advances, producing bioactive FBN1 remains technically demanding, limiting its widespread use. Ongoing efforts focus on improving yield, scalability, and functional fidelity to better model diseases and advance therapeutic interventions.
