Description
Guanine nucleotide-binding proteins (G proteins are involved as a modulator or transducer in various transmembrane signaling systems (Probable. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction (Probable. Involved in the regulation of plant architecture, panicle erectness, panicle and grain length, grain weight, and grain yield. Involved in the regulation of grain size.
