Heterotrimeric G-proteins bind to cell-surface receptors and are integral in transmission of signals from outside the cell. Upon activation of the Gα subunit by binding of GTP, the Gα and Gβγ subunits dissociate and interact with effector proteins for signal transduction. Regulatory proteins with the 19-amino-acid GoLoco motif can bind to Gα subunits and maintain G-protein subunit dissociation in the absence of Gα activation. Here we describe the structural determinants of GoLoco activity as…

Drosophila GoLoco-protein Pins as a target of Gαo-mediated G protein coupled receptor signaling
TLDR
The biochemical and genetic experiments as well as structural modeling show that the poly-GoLoco protein Pins binds to both the GDP- and GTP-forms of Drosophila G αo, and conclude that Pins, through its GoLoco domain 1, is a target for Gαo-mediated GPCR signaling.
A Structural Determinant That Renders Gαi Sensitive to Activation by GIV/Girdin Is Required to Promote Cell Migration*
TLDR
A novel structural determinant in Gαi3 necessary for its regulation by GIV/girdin, a guanine-nucleotide exchange factor (GEF) that activates G αi subunits is discovered that represents an attractive target site for designing small molecules to disrupt the Gαo-GIV interface for therapeutic purposes.
Structural Determinants of Affinity Enhancement between GoLoco Motifs and G-Protein α Subunit Mutants*
TLDR
The crystal structure of Gαi1Q147L bound to the RGS14 GoLoco motif revealed disorder among three peptide residues surrounding a well defined Leu-147 side chain, and it is concluded that mutation of Glu-147 to leucine creates a hydrophobic surface favorably buried uponGoLoco peptide binding, yet the hydrophilic Leu -147 also promotes flexibility among residues 511–513 of the R GS14 Goloco peptides.
Molecular architecture of Gαo and the structural basis for RGS16-mediated deactivation
TLDR
The 2.9 Å crystal structure of the enigmatic, neuronal G protein Gαo in the GTP hydrolytic transition state, complexed with RGS16 is presented, affording insight to receptor, GAP and effector specificity.
Activation of heterotrimeric G-proteins independent of a G-protein coupled receptor and the implications for signal processing
TLDR
The discovery that AGS proteins provide a foundation for the concept that heterotrimeric G-protein subunits are processing signals within the cell involving intrinsic cues that do not involve the classical signal input from a cell surface GPCR.
The GAPs, GEFs, and GDIs of heterotrimeric G-protein alpha subunits
TLDR
More recent discoveries that have highlighted newly-appreciated roles for RGS proteins beyond mere negative regulators of 7TM signaling are reviewed, including the RGS-box-containing, RhoA-specific guanine nucleotide exchange factors (RGS-RhoGEFs) that serve as Gα effectors to couple 7TM and semaphorin receptor signaling to RHoA activation.
The GAPs, GEFs, and GDIs of heterotrimeric G-protein alpha subunits
TLDR
This work reviews more recent discoveries that have highlighted newly-appreciated roles for RGS proteins beyond mere negative regulators of 7TM signaling, and reviews the discovery of novel biochemical activities that also impinge on the guanine nucleotide binding and hydrolysis cycle of Gα subunits.
Differential G-alpha interaction capacities of the GoLoco motifs in Rap GTPase activating proteins.
The RGS14 GoLoco Domain Discriminates among Gαi Isoforms*
TLDR
The striking selectivity observed for RGS14 GDI activity in vitro points to G αi1 and Gαi3 as the likely targets of R GS14-GoLoco regulation in vivo.
The Crystal Structure of a Self-Activating G Protein α Subunit Reveals Its Distinct Mechanism of Signal Initiation
TLDR

RGS12 and RGS14 GoLoco Motifs Are GαiInteraction Sites with Guanine Nucleotide Dissociation Inhibitor Activity*
TLDR
The results indicate that both RGS12 and RGS14 harbor two distinctly different Gα interaction sites: a previously recognized RGS box possessing Gαi/o GAP activity and a C-terminal GoLoco region exhibiting G αi GDI activity, which suggests that RGS 12 and R GS14 participate in a complex coordination of G-protein signaling beyond simple Gα G AP activity.
AGS3 Inhibits GDP Dissociation from Gα Subunits of the Gi Family and Rhodopsin-dependent Activation of Transducin*
TLDR
The results suggest that proteins containing GPR motifs, in addition to their potential role as G protein-coupled receptor-independent activators of Gβγ signaling pathways, act as GDP dissociation inhibitors and negatively regulate the activation of a G protein by a Gprotein-cOUpled receptor.
Stabilization of the GDP-bound Conformation of Giα by a Peptide Derived from the G-protein Regulatory Motif of AGS3*
TLDR
The AGS3-GPR motif presents an opportunity for selective control of Giα- and Gβγ−regulated effector systems, and the GPR motif allows for alternative modes of signal input to G-protein signaling systems.
Structural basis of activity and subunit recognition in G protein heterotrimers.
Inhibition of GDP/GTP exchange on G alpha subunits by proteins containing G-protein regulatory motifs.
TLDR
The results suggest that GPR proteins are potent GDP dissociation inhibitors for Gialpha-like Galpha subunits in vitro, and in this capacity they may inhibit GPCR/Gi protein signaling in vivo.
Structures of active conformations of Gi alpha 1 and the mechanism of GTP hydrolysis.
TLDR
AlF4- complexes formed by the G protein Gi alpha 1 demonstrate specific roles in transition-state stabilization for two highly conserved residues, suggesting a mechanism that may promote release of the beta gamma subunit complex when the alpha subunit is activated by GTP.
Activator of G protein signaling 3 is a guanine dissociation inhibitor for Galpha i subunits.
TLDR
Inhibition of the Galpha subunit and stimulation of heterotrimeric G protein signaling, presumably by stimulating Gbetagamma, extend the possibilities for modulating signal transduction through heterotimeric G proteins.

Tertiary and Quaternary Structural Changes in Giα1 Induced by GTP Hydrolysis
TLDR
The amino and carboxyl termini, which contain receptor and βγ binding determinants, are disordered in the complex with GTP, but are organized into a compact microdomain on GDP hydrolysis, suggesting that multimers of α subunits or heterotrimers may play a role in signal transduction.
Receptor-independent Activators of Heterotrimeric G-protein Signaling Pathways*
TLDR
AGS proteins provide unexpected mechanisms for input to heterotrimeric G-protein signaling pathways and may also serve as novel binding partners for Gα and Gβγ that allow the subunits to subserve functions that do not require initialheterotrimer formation.
