Glucocorticoid receptor phosphorylation in mouse L-cells.
This paper summarizes our observations on the phosphorylation state of untransformed and transformed glucocorticoid receptors isolated from 32P-labeled L-cells. The 300-350-kDa 9S untransformed murine glucocorticoid receptor complex is composed of a 100-kDa steroid-binding phosphoprotein and one or possibly two units of the 90-kDa heat shock protein (hsp90), which is also a phosphoprotein. Tran...
متن کاملPhosphorylation 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 کاملDomain structure of the glucocorticoid receptor protein.
The purified rat liver glucocorticoid receptor protein was analyzed by limited proteolysis and amino acid sequence determination. The NH2 terminus appears to be blocked. The steroid-binding domain, defined by a unique tryptic cleavage site, corresponds to the COOH-terminal part of the protein with the domain border in the region of residue 518. The DNA-binding domain, defined by a region with c...
متن کاملG-protein Coupled Receptor Dimerization
A growing body of evidence suggests that GPCRs exist and function as dimers or higher oligomers. The evidence for GPCR dimerization comes from biochemical, biophysical and functional studies. In addition, researchers have shown the occurrence of heterodimerization between different members of the GPCR family. Two receptors can interact with each other to make a dimer through their extracellular...
متن کاملPhosphorylation of Glucocorticoid Receptor-associated and Free Forms of the -90-kDa Heat Shock Protein before and after Receptor Activation*
Several lines of evidence have suggested that glucocorticoid receptor function may be regulated by phosphorylation-dephosphorylation reactions, and it has been proposed that dephosphorylation accompanies activation to the DNA-binding form. The phosphate content of the -100-kDa steroid-binding protein has been determined directly and was found not to change during activation in intact cells (Men...
