title: Nongenomic interactions of retinoic acid and thyroid hormone at the plasma membrane.
abstract: Both thyroxine (T4) and 3,3'5-L-tri-iodothyronine (T3) can activate the calcium-magnesium-dependent adenosine triphosphatase (ATP-ase) in plasma membranes of enucleate erythrocytes. This activation of Ca2+-ATPase is blocked by retinoic acid and perhaps by competing T4-binding sites on the membranes.
