The catecholamine-stimulated cotransport of sodium and potassium ions across the plasma membrane of the turkey erythrocyte was previously found to be associated with increased 32P incorporation into a high molecular weight protein. To determine the subcellular localization of this phosphorylated protein, which we have termed goblin, a new method has been developed for isolation of pure plasma membranes from turkey erythrocytes. With this method, it has been demonstrated that goblin is located in the plasma membrane. Goblin is not extracted by solutions of low or high ionic strength but is partially extracted by nonionic detergents, indicating that it is not a component of turkey erythrocyte spectrin and suggesting that it may be an intrinsic protein of the plasma membrane. The data are compatible with a possible role for goblin in the hormonal control of ion movements across the plasma membrane.
