Mannose-6-phosphate receptor binding domain superfamily
IPR009011
Definition
Mannose-6-phosphate receptors (MPRs) are transmembrane proteins involved in the transport of lysosomal enzymes from the Golgi complex and the cell surface to lysosomes PMID:1376319. Lysosomal enzymes bearing phosphomannosyl residues bind specifically to MPRs in the Golgi apparatus and the resulting receptor-ligand complex is transported to an acidic prelysosomal compartment, where the low pH mediates dissociation of the complex. There are two distinct MPRs that function in the recognition of mannose-6-phosphate-containing proteins: the cation-dependent MPR (CD-MPR) and the cation-independent MPR (CI-MPR). The CI-MPR is also known as the insulin-like growth factor II receptor, a multi-functional protein implicated in tumour suppression.
8 human proteins with this domain
Each is a reviewed human protein in the Seroatlas serome and a potential autoantibody target; this domain groups them into one antibody-relevant category. Every entry links to its own record.
