title: G proteins in cellular control.
abstract: In the past year, cDNA cloning has revealed substantial diversity in G protein alpha, beta and gamma subunits. The number of cellular functions recognized to be controlled by G proteins is also increasing. Most G proteins are associated with the cytoplasmic surface of the plasma membrane, and molecular mechanisms for membrane association of certain G protein subunits have been defined recently. Mutations in G protein subunits, both artificially induced and naturally occurring, have provided important insights into G protein structure and function.
