The mannose 6-phosphate/insulin-like growth factor II receptor (M6P/IGF2R) is a multifunctional, type I transmembrane receptor that is a member of the P-type lectin family. A large, extracytoplasmic (EC) region of the M6P/IGF2R binds various ligands, allowing the receptor to regulate multiple biological functions, including the role as a tumor suppressor. Two major classes of ligands, M6P-glycosylated (i.e. any proteins that bear M6P due to post-translational modification in the trans-Golgi network (TGN)) and non-glycosylated (i.e., the mitogen insulin-like growth factor II (IGF-II)), bind within distinct regions of the EC of the receptor and are trafficked to the lysosome. The M6P/IGF2R as …
