产品描述：

background: 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.
