Tubulin as a regulator of G-protein signaling.
Tubulin is known to form high-affinity complexes with certain G proteins. The formation of such complexes allows tubulin to activate Galpha and fosters a system whereby elements of the cytoskeleton can influence G-protein signaling. This article describes the interaction between tubulin and G proteins and discusses methods for examining this interaction.
