Characterization of the endosomal sorting signal of the cation-dependent mannose 6-phosphate receptor.
Intracellular cycling of the cation-dependent mannose 6-phosphate receptor (CD-MPR) between different compartments is directed by signals localized in its cytoplasmic tail. A di-aromatic motif (Phe18-Trp19 with Trp19 as the key residue) in its cytoplasmic tail is required for the sorting of the receptor from late endosomes back to the Golgi apparatus. However, the cation-independent mannose 6-p...
متن کاملLigand interactions of the cation-dependent mannose 6-phosphate receptor. Comparison with the cation-independent mannose 6-phosphate receptor.
The interactions of the bovine cation-dependent mannose 6-phosphate receptor with monovalent and divalent ligands have been studied by equilibrium dialysis. This receptor appears to be a homodimer or a tetramer. Each mole of receptor monomer bound 1.2 mol of the monovalent ligands, mannose 6-phosphate and pentamannose phosphate with Kd values of 8 X 10(-6) M and 6 X 10(-6) M, respectively and 0...
متن کاملA determinant in the cytoplasmic tail of the cation-dependent mannose 6- phosphate receptor prevents trafficking to lysosomes
The bovine cation-dependent mannose 6-phosphate receptor (CD-MPR) is a type 1 transmembrane protein that cycles between the trans-Golgi network, endosomes, and the plasma membrane. When the terminal 40 residues were deleted from the 67-amino acid cytoplasmic tail of the CD-MPR, the half-life of the receptor was drastically decreased and the mutant receptor was recovered in lysosomes. Analysis o...
متن کاملTransport of surface mannose 6-phosphate receptor to the Golgi complex in cultured human cells.
The cation-independent mannose 6-phosphate receptor (MPRCI) functions in the packaging of both newly made and extracellular lysosomal enzymes into lysosomes. The subcellular location of MPRCI reflects these two functions; receptor is found in the Golgi complex, in endosomes, and on the cell surface. To learn about the intracellular pathway followed by surface receptor and to study the relations...
متن کاملTargeting of beta-glucuronidase to lysosomes in mannose 6-phosphate receptor-deficient MOPC 315 cells
The murine plasma cell line MOPC 315 efficiently targets newly synthesized acid hydrolases to lysosomes in spite of a marked deficiency in the level of the mannose 6-phosphate receptor (Gabel, C., D. Goldberg, and S. Kornfeld, 1983, Proc. Natl. Acad. Sci. USA, 80:775-779). To better understand the routing of lysosomal enzymes in this cell line, pulse-chase experiments were performed with [2-3H]...
