The effect of alpha subunit of G protein on signaling pathway needs to be explained. Concept introduction: Heterotrimeric globular proteins are comprised of alpha, beta, and gamma subunits. Alpha subunit ties effectively to one of the two guanine subunits, GTP or GDP. Alpha subunit joins with GTP and leaves the other subunits in order to activate secondary messengers.
