a multifunctional type I transmembrane protein receptor that binds insulin-like growth factor 2 at the cell surface and mannose-6-phosphate-tagged proteins in the trans-Golgi network. Also known as the cation-independent mannose-6 phosphate (M6P) receptor. Clears IGF2 from the cell surface to attenuate signaling, and transports M6P-tagged lysosomal enzymes from the Golgi complex and the cell surface to lysosomes. M6P-tagged lysosomal enzymes bind specifically to mannose-6- phosphate receptors in the Golgi apparatus and the resulting receptor-ligand complex is transported to an acidic prelyosomal compartment where the low pH mediates the dissociation of the complex. Acts as a positive regulator of T-cell coactivation, by binding DPP4. Belongs to the MRL1/IGF2R family. Note: This description may include information from UniProtKB.
