We have purified a novel GTP-binding protein, designated as the smg-25A protein (smg p25A), from bovine brain membranes and determined its primary structure. In the present studies, the smg-25A mRNA levels in various tissues have been studied. The 1.6-kilobase smg-25A mRNA is detected in rat brain by Northern blot analysis. This mRNA is not detected in other rat tissues including thymus, lung, heart, liver, small intestine, kidney, and skeletal muscle. The 1.6-kilobase smg-25A mRNA is also detected in bovine adrenal medulla but not in the cortex. Moreover, this mRNA is detected in rat pheochromocytoma PC-12 cells and its level increases after differentiation of the cells into sympathetic neuron-like cells in response to nerve growth factor or dibutyryl cyclic AMP. This mRNA level does not increase in response to 12-O-tetradecanoylphorbol-13-acetate incapable of inducing differentiation. These results suggest that the smg-25A gene is specifically expressed in nerve tissues and that smg p25A plays a role in some neuronal functions.
