Heterotrimeric G protein signaling: Getting inside the cell

Cell. 2006 Jul 14;126(1):25-7. doi: 10.1016/j.cell.2006.06.026.

Abstract

Heterotrimeric G proteins have traditionally been thought to transduce signals at the plasma membrane. In this issue, Slessareva et al. (2006) now show that a G protein alpha subunit acts at the endosome to stimulate a phosphatidylinositol 3-kinase to help yeast respond to mating pheromones.
