背景信息

**Background of IGF2R Recombinant Protein**

The insulin-like growth factor 2 receptor (IGF2R), also known as the cation-independent mannose-6-phosphate receptor (CI-M6PR), is a multifunctional transmembrane protein critical for regulating cell growth, lysosomal enzyme trafficking, and ligand degradation. It binds insulin-like growth factor 2 (IGF2), a potent mitogen, to control its extracellular levels by internalizing and degrading it via lysosomes. This process helps prevent excessive IGF2 signaling, which is linked to developmental abnormalities and cancer progression.

Structurally, IGF2R contains a large extracellular domain with multiple ligand-binding sites, a transmembrane region, and a short cytoplasmic tail mediating endocytosis and intracellular trafficking. Beyond IGF2. it interacts with mannose-6-phosphate (M6P)-tagged lysosomal enzymes, ensuring their proper transport to lysosomes. Dysregulation of IGF2R is associated with diseases like cancers, neurodegenerative disorders, and lysosomal storage diseases due to impaired enzyme trafficking.

Recombinant IGF2R proteins are engineered in vitro using expression systems (e.g., mammalian cells, bacteria) to study its biochemical functions, ligand interactions, and therapeutic potential. These proteins retain key domains for binding IGF2. M6P enzymes, and other ligands, enabling research into receptor-ligand dynamics, cancer mechanisms, and lysosomal disorders. Recombinant IGF2R also serves as a tool for developing targeted therapies, such as blocking IGF2-driven tumor growth or enhancing lysosomal enzyme delivery in genetic diseases.

As an imprinted gene (maternally expressed), IGF2R's role in development and disease highlights its importance in cellular homeostasis, making it a focal point for biomedical research and therapeutic innovation.
