RGS proteins the early days

Prog Mol Biol Transl Sci. 2009:86:1-14. doi: 10.1016/S1877-1173(09)86001-8. Epub 2009 Oct 7.


This chapter describes events that transpired in the mid-1990s during the pioneering days of RGS protein research. This period began with early studies of Sst2 in yeast, EGL-10 in nematodes, and the discovery of an expansive family of similar proteins in animals. Within a period of only 2 years, the RGS gene family was first identified, functionally characterized in diverse organisms, and their mechanism of action firmly established. Long considered a three-component signaling system (comprised of a receptor, G protein, and effector enzyme), the discovery of RGS proteins revealed a critical new component of the signaling apparatus, and resolved a long-recognized discrepancy in the rates of G protein inactivation measured in vitro and in vivo.
