CC -!- FUNCTION: Heterotrimeric guanine nucleotide-binding proteins (G
CC proteins) function as transducers downstream of G protein-coupled
CC receptors (GPCRs) in numerous signaling cascades. The alpha chain
CC contains the guanine nucleotide binding site and alternates between an
CC active, GTP-bound state and an inactive, GDP-bound state. Signaling by
CC an activated GPCR promotes GDP release and GTP binding. The alpha
CC subunit has a low GTPase activity that converts bound GTP to GDP,
CC thereby terminating the signal (PubMed:2159473). Both GDP release and
CC GTP hydrolysis are modulated by numerous regulatory proteins. Signaling
CC is mediated via effector proteins, such as adenylate cyclase. Inhibits
CC adenylate cyclase activity, leading to decreased intracellular cAMP
CC levels. Stimulates the activity of receptor-regulated K(+) channels.
CC The active GTP-bound form prevents the association of RGS14 with
CC centrosomes and is required for the translocation of RGS14 from the
CC cytoplasm to the plasma membrane. May play a role in cell division.
CC {ECO:0000250|UniProtKB:P08754, ECO:0000269|PubMed:2159473}.
CC -!- SUBUNIT: Heterotrimeric G proteins are composed of 3 units; alpha, beta
CC and gamma. The alpha subunit contains the guanine nucleotide binding
CC site (PubMed:2159473). GTP binding causes dissociation of the
CC heterotrimer, liberating the individual subunits so that they can
CC interact with downstream effector proteins. Forms a complex with
CC CCDC88A/GIV and EGFR which leads to enhanced EGFR signaling and
CC triggering of cell migration; ligand stimulation is required for
CC recruitment of GNAI3 to the complex (PubMed:20462955). Interacts
CC (inactive GDP-bound form) with CCDC88A/GIV (via GBA motif); the
CC interaction leads to activation of GNAI3 (PubMed:19211784). Interacts
CC (inactive GDP-bound form) with CCDC88C/DAPLE (via GBA motif); the
CC interaction leads to activation of GNAI3 (By similarity). Interacts
CC (inactive GDP-bound form) with NUCB1 (via GBA motif) and NUCB2 (via GBA
CC motif); the interaction leads to activation of GNAI3 (PubMed:21653697).
CC Interacts (inactive GDP-bound form) with PLCD4 (via GBA motif); the
CC interaction leads to activation of GNAI3 (By similarity). Interacts
CC with INSR; the interaction is probably mediated by CCDC88A/GIV
CC (PubMed:25187647). Interacts with GPSM1 (PubMed:11121039). Interacts
CC (GDP-bound form) with GPSM2 (via GoLoco domains). Does not interact
CC with RGS2. Interacts with RGS8 and RGS10; this strongly enhances the
CC intrinsic GTPase activity (By similarity). Interacts with RGS12
CC (PubMed:11387333). Interacts with RGS16; this strongly enhances the
CC intrinsic GTPase activity (By similarity). Interacts (via active
CC GTP- or inactive GDP-bound form) with RGS14 (PubMed:11387333,
CC PubMed:16870394). {ECO:0000250|UniProtKB:P08754,
