The human urine mannose 6-phosphate glycoproteome.
Glycoproteins containing the mannose 6-phosphate (Man-6-P) modification represent a class of proteins of considerable biomedical importance. They include over sixty different soluble lysosomal hydrolases and accessory proteins, deficiencies of which result in over forty different known human genetic diseases. In addition, there are patients with lysosomal storage diseases of unknown etiology an...
متن کاملThe mannose 6-phosphate glycoprotein proteome.
Most luminal lysosomal proteins are synthesized as precursors containing mannose 6-phosphate (Man6-P) and a number of recent studies have conducted affinity purification of Man6-P containing proteins as a step toward defining the composition of the lysosome. Approximately 60 known lysosomal proteins have been found in such studies as well as many other Man-6-P glycoproteins, some of which repre...
متن کاملLigand interactions of the cation-independent mannose 6-phosphate receptor. The stoichiometry of mannose 6-phosphate binding.
The interaction of the bovine cation-independent mannose 6-phosphate receptor with a variety of phosphorylated ligands has been studied using equilibrium dialysis and immobilized receptor to measure ligand binding. The dissociation constants for mannose 6-phosphate, pentamannose phosphate, bovine testes beta-galactosidase, and a high mannose oligosaccharide with two phosphomonoesters were 7 X 1...
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 کاملGranzyme-mediated cytotoxicity does not involve the mannose 6-phosphate receptors on target cells.
Cytotoxic T lymphocytes (CTL) and natural killer cells secrete granzymes to kill infected or transformed cells. The mannose 6-phosphate receptor (Mpr) 300 on target cells has been reported to function as receptor for secreted granzyme B. Using lymphoblasts and mouse embryonal fibroblast lines from Mpr300 and Mpr46 knockout mice, we show here that both receptors are not essential for CTL-induced...
