  • Title: Isolation and characterization of rat liver nuclear glucocorticoid receptor.
    Author: Govindan MV.
    Journal: Biochim Biophys Acta; 1980 Aug 13; 631(2):327-33. PubMed ID: 6773588.
    Abstract:
    The rat liver nuclear glucocorticoid receptor has a molecular weight of 90 000. Using antibody bound to the stationary matrix, the cytosol and nuclear glucocorticoid receptors from rat liver were purified. The translocation of glucocorticoid receptor from rat liver cytosol into the nucleus was studied using immunoaffinity chromatography. Immediately after the intraperitioneal injection of rats with the hormone, the receptor translocation started and was complete within 10 min. The 90 000 dalton nuclear receptor component is identical to the 90 000 dalton cytosol component. They have identical molecular weights in the same gel electrophoresis system and produce identical peptide fragments after digestion with Staphyolococcal aureus V8 protease. The receptor component enriched by immunoaffinity chromatography from cytosol of adrenalectomised rats contained mainly a 45 000 dalton component.
