CC -!- FUNCTION: Guanine nucleotide-binding proteins (G proteins) are
CC involved as modulators or transducers in various transmembrane
CC signaling systems. The G(i) proteins are involved in hormonal
CC regulation of adenylate cyclase: they inhibit the cyclase in
CC response to beta-adrenergic stimuli.
CC -!- SUBUNIT: G proteins are composed of 3 units; alpha, beta and
CC gamma. The alpha chain contains the guanine nucleotide binding
CC site.
CC -!- SIMILARITY: Belongs to the G-alpha family. G(i/o/t/z) subfamily.
