Plant G proteins: the different faces of GPA1

Curr Biol. 2001 Oct 30;11(21):R869-71. doi: 10.1016/s0960-9822(01)00519-x.

Abstract

Biochemical studies suggest that G proteins mediate a variety of signaling processes in plants, yet Arabidopsis has only one gene, GPA1, for a canonical G protein alpha subunit. Recent studies indicate that the GPA1 protein is involved in a number of very different cellular processes.
