Glucocorticoid receptor of frog (Rana esculenta) liver

The presence of a glucocorticoid soluble receptor is demonstrated in frog liver cytosol. The kinetic characterization of frog liver cytosolic receptor for glucocorticoids is reported and its steroid specificity assessed. Results indicate a gross similarity between frog liver and mammalian glucocorticoid receptor, being a major difference the reduced binding capacity.
