The active role of beta gamma in signal transduction

Curr Opin Cell Biol. 1994 Apr;6(2):198-203. doi: 10.1016/0955-0674(94)90136-8.

Abstract

Many receptors that sense the environment effect intracellular regulation through stimulation of heterotrimeric G proteins and the consequences thereof. While prominence was originally given to the alpha-subunits of G proteins as the pathway for downstream regulation, very active roles for the beta gamma-subunits have emerged in the past year. Recent experiments highlight the versatility of beta gamma-subunits in these regulatory pathways, but also emphasize some fundamental questions that remain.
