The 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 کاملThe 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 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 کاملAn ELISA method to quantify the mannose 6-phosphate receptors.
Mannose 6-phosphate receptor proteins mediate transport of lysosomal enzymes to lysosomes in eukaryotes. Two receptors designated as MPR 300 and MPR 46 based on their apparent molecular mass have been well studied from human and bovine liver. In humans, it has been shown that the receptors are present in different concentrations in different tissues. In the present study, MPR 300 and MPR 46 wer...
