| Abstract: | The glucocorticoid hormone-receptor complex has been shown to exist in several forms. The transformation status of various forms of the complex isolated from rat thymus cytosol in the presence of molybdate was determined. The non-transformed receptor had a higher affinity for DEAE-cellulose than the transformed receptor. The rate at which the non-transformed complex was transformed to a smaller form with a low affinity for DEAE-cellulose by exposure to salt was greater in the absence of molybdate than in its presence. We conclude that salt-induced transformation of the complex is retarded but not prevented by molybdate and is associated with subunit dissociation. |
