Wong et al., Hong Kong, Hong Kong. In Mol Cell Biochem, Mar 2015
It has recently been demonstrated in reconstitution experiments that the AGS3/Gα(i/o)-GDP complex may act as a substrate of resistance to inhibitors of cholinesterase 8A (Ric-8A), a guanine exchange factor (GEF) for heterotrimeric Gα proteins.

Ric-8A is a soluble cytoplasmic protein essential for embryonic development that acts as both a guanine nucleotide exchange factor (GEF) and a chaperone for Gα subunits of the i, q, and 12/13 classes.
The guanine-exchange factor Ric8a binds to the Ca²⁺ sensor NCS-1 to regulate synapse number and neurotransmitter release.
Ferrús et al., Madrid, Spain. In J Cell Sci, 2014
We show here that Drosophila Ric8a (a homolog of mammalian synembryn, which is also known as Ric8a), a receptor-independent activator of G protein complexes, binds to Frq2 but not to the virtually identical homolog Frq1.

Chern et al., Taipei, Taiwan. In Neurosignals, 2008
Based on recent studies on AC-interacting proteins (particularly Snapin and Ric8a), this review focuses on the importance and possible involvement of AC-interacting proteins in (1) the association of the cAMP signaling pathway with various cellular machineries and (2) the coordination of tightly regulated cAMP signaling by other signaling molecules.
Heterotrimeric G proteins in C. elegans.
Mendel et al., Pasadena, United States. In Wormbook, 2005
The rate of G protein activation can be enhanced by the guanine-nucleotide exchange factor, RIC-8, while the rate of GTP hydrolysis can be enhanced by RGS proteins such as EGL-10 and EAT-16.
