CC -!- FUNCTION: Guanine nucleotide-binding proteins (G proteins) are involved
CC as modulators or transducers in various transmembrane signaling
CC systems. The G(i) proteins are involved in hormonal regulation of
CC adenylate cyclase: they inhibit the cyclase in response to beta-
CC adrenergic stimuli. May play a role in cell division.
CC {ECO:0000256|ARBA:ARBA00037181}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|ARBA:ARBA00004236}.
CC Cytoplasm, cytoskeleton, microtubule organizing center, centrosome
CC {ECO:0000256|ARBA:ARBA00004300}. Membrane
CC {ECO:0000256|ARBA:ARBA00004370}.
CC -!- SIMILARITY: Belongs to the G-alpha family. G(i/o/t/z) subfamily.
CC {ECO:0000256|ARBA:ARBA00006628}.
