title: Determining cellular role of G alpha 12.
abstract: Using the expression strategies described here, we have demonstrated a model system whereby the sequential signaling events involved in cell proliferation and subsequent transformation regulated by G alpha 12 can be investigated. The model system presented here can also be used to study the temporal interrelationships between small GTPases, kinases, and other signaling proteins involved in G alpha 12-signaling pathways. Further analyses using this model system and the strategies presented here should provide valuable clues in defining the signaling network regulated by G alpha 12 in stimulating cell proliferation and oncogenic transformation.
