Phosphorylation of rat liver glucocorticoid receptor.
Rat liver glucocorticoid-receptor complex (GRc) was purified 2000-fold by a combination of methods including (NH4)2SO4-fractionation and phosphocellulose and DNA-cellulose chromatography. The purified glucocorticoid receptor preparation contained a major peptide of Mr = 90,000 and the GRc sedimented as 4 S in 5-20% sucrose gradients. An additional peptide of Mr = 45,000 (45K) was also observed....
متن کاملPurification of the glucocorticoid receptor from rat liver cytosol.
The [3H]-triamcinolone acetonide-labeled glucocorticoid receptor from rat liver cytosol was purified to 85% homogeneity according to sodium dodecyl sulfate gel electrophoresis. It consisted of one subunit with a molecular weight of 89,000 and had one ligand-binding site per molecule. The purification involved sequential chromatography on phosphocellulose, DNA-cellulose twice, and Sephadex G-200...
متن کاملInteraction of rat liver glucocorticoid receptor with sodium tungstate.
Effects of sodium tungstate on various properties of rat liver glucocorticoid receptor were examined at pH7 and pH 8. At pH 7, [3H]triamcinolone acetonide binding in rat liver cytosol preparations was completely blocked in the presence of 10--20 mM-sodium tungstate at 4 degrees C, whereas at 37 degrees C a 30 min incubation of cytosol receptor preparation with 1 mM-sodium tungstate reduced the ...
متن کاملCharacterization of the purified activated glucocorticoid receptor from rat liver cytosol.
The activated glucocorticoid receptor (GR) from rat liver cytosol was purified by sequential chromatography on DNA-cellulose and DEAE-Sepharose. Analysis by sodium dodecyl sulfate-gel electrophoresis demonstrated a main band with Mr = 94,000 (94K band). Two minor bands with Mr = 79,000 (79K band) and 72,000 (72K band) were also seen in this preparation. Photoaffinity labeling showed that the ho...
متن کاملThe galactose-specific receptor system in rat liver during development.
The number and distribution of galactose-specific binding sites were investigated in rat liver cells during perinatal development. Ligand binding to hepatocytes, macrophages and endothelial cells was followed with in vitro and in situ experiments by electron microscopy, using lactosylated bovine serum albumin adsorbed onto 5 nm colloidal gold particles as ligand. Binding capacity, starting at a...
