CC -!- FUNCTION: Guanine nucleotide-binding proteins (G proteins) are involved
CC as modulators or transducers in various transmembrane signaling
CC systems. {ECO:0000256|RuleBase:RU368109}.
CC -!- SUBUNIT: G proteins are composed of 3 units; alpha, beta and gamma. The
CC alpha chain contains the guanine nucleotide binding site.
CC {ECO:0000256|RuleBase:RU368109}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|RuleBase:RU368109}.
CC -!- DOMAIN: The helical domain is required for self-activation.
CC {ECO:0000256|RuleBase:RU368109}.
CC -!- SIMILARITY: Belongs to the G-alpha family.
CC {ECO:0000256|RuleBase:RU368109}.
