Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0005322
UniProt IDP11717
Primary gene name(s)IGF2R
Synonym gene name(s)MPRI
Protein nameCation-independent mannose-6-phosphate receptor
Protein functionTransport 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. {ECO:0000269|PubMed:10900005}.
Subcellular locationLysosome membrane {ECO:0000269|PubMed:10900005};
Single-pass type I membrane protein {ECO:0000269|PubMed:10900005}. Note=Colocalized with DPP4 in internalized cytoplasmic vesicles adjacent to the cell surface.
