G-Protein Regulation of Plant K+ Channels

  • Chapter
Signal Transduction in Plant Growth and Development

Part of the book series: Plant Gene Research ((GENE))

Abstract

A diversity of GTP-binding proteins is found in living organisms. These include small G proteins involved in vesicle trafficking and secretion (e.g., rab proteins), cytoskeleton organization (e.g., rho and rac proteins), and cell growth and differentiation (e.g., the proto-oncogenic ras proteins), as well as tubulins, signal-recognition particles (SRPS), translation factors, and the signal-transducing heterotrimeric G proteins (Kaziro et al., 1991; Marsh and Goode, 1993; Boguski and McCormick, 1993). Common to all of these proteins is a mechanism in which the protein is activated upon binding of GTP and inactivated by subsequent GTP hydrolysis. This chapter focuses on the signal-transducing G proteins (reviewed in Gilman, 1987; Neer and Clapham, 1988; Simon et al., 1991) and their roles as regulators of plant ion channels. Other plant members of the GTPase superfamily are discussed in detail by Yang (1996) as well as in recent reviews (Kaufman, 1994; Ma, 1994; Terryn et al., 1993).
