Abstract excerpt

The occurrence of individual G proteins within Golgi membranes from liver and from adrenal medulla were analyzed by Western blotting. Two splice variants of G alpha s and also G alpha i-3 were found in both tissues. Additionally, G alpha i-2, its 43-kDa splice variant and G alpha o were strongly labeled in Golgi of adrenal medulla. Golgi preparations of liver contained comparable quantities of G alpha i-2 and a...
