+==G PROTEIN HETEROTRIMER GI_ALPHA_1 BETA_1 GAMMA_2 WITH GDP BOUND==
-The crystallographic structure of the G protein heterotrimer Gi alpha, 1(GDP)beta 1 gamma 2 (at 2.3 A) reveals two nonoverlapping regions of, contact between alpha and beta, an extended interface between beta and, nearly all of gamma, and limited interaction of alpha with gamma. The, major alpha/beta interface covers switch II of alpha, and GTP-induced, rearrangement of switch II causes subunit dissociation during signaling., Alterations in GDP binding in the heterotrimer (compared with alpha-GDP), explain stabilization of the inactive conformation of alpha by beta gamma., Repeated WD motifs in beta form a circularized sevenfold beta propeller., The conserved cores of these motifs are a scaffold for display of their, more variable linkers on the exterior face of each propeller blade.

+== Function ==
+[https://www.uniprot.org/uniprot/GNAI1_RAT GNAI1_RAT] Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. The G(i) proteins are involved in hormonal regulation of adenylate cyclase: they inhibit the cyclase in response to beta-adrenergic stimuli. The inactive GDP-bound form prevents the association of RGS14 with centrosomes and is required for the translocation of RGS14 from the cytoplasm to the plasma membrane. May play a role in cell division.<ref>PMID:16870394</ref>
