IGF2R Protein, Human (Domain 1-3, HEK293, His-Avi)

IGF2R proteins coordinate cellular processes by transporting phosphorylated lysosomal enzymes from the Golgi complex to lysosomes. Lysosomal enzymes with phosphomannosyl residues bind to mannose-6-phosphate receptors in the Golgi apparatus, form complexes, and transport to the acidic prelysosomal compartment. IGF2R Protein, Human (Domain 1-3, HEK293, His-Avi) is the recombinant human-derived IGF2R protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of IGF2R Protein, Human (Domain 1-3, HEK293, His-Avi) is 422 a.a., with molecular weight of 55-65 kDa.

IGF2R Protein serves as a crucial mediator in cellular processes, orchestrating the transport of phosphorylated lysosomal enzymes from the Golgi complex and the cell surface to lysosomes. Lysosomal enzymes carrying phosphomannosyl residues specifically bind to mannose-6-phosphate receptors in the Golgi apparatus, forming a receptor-ligand complex that is transported to an acidic prelysosomal compartment. The low pH in this compartment facilitates the dissociation of the complex, after which the receptor is recycled back to the Golgi for further trafficking through its interaction with the retromer. Additionally, IGF2R binds IGF2 and acts as a positive regulator of T-cell coactivation by directly interacting with DPP4. The protein further engages with HA-I and HA-II plasma membrane adapters, demonstrating its versatile molecular interactions. Its binding to the heterotrimeric retromer cargo-selective complex highlights its involvement in retrograde trafficking from endosomes to the Golgi apparatus, underscoring its essential role in intracellular transport and cellular homeostasis.
