Transport of phosphorylated lysosomal enzymes from the Golgi complex and the cell surface to lysosomes. Lysosomal enzymes bearing phosphomannosyl residues 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. This receptor also binds IGF2. Acts as a positive regulator of T-cell coactivation, by binding DPP4.

Titration of the IGF2R antibody may be required due to differences in protocols and substrate sensitivity.

A portion of amino acids 2424-2458 from the human protein was used as the immunogen for the IGF2R antibody.

Aliquot the IGF2R antibody and store frozen at -20oC or colder.Avoid repeated freeze-thaw cycles.
