Data show that synaptosome associated protein 25 (SNAP25)Delta3 mutation has a twofold reduction in GTP-binding protein beta/gamma (Gbetagamma) binding.
Title: Disabling the Gβγ-SNARE interaction disrupts GPCR-mediated presynaptic inhibition, leading to physiological and behavioral phenotypes.
During corticogenesis, a cilium-transduced, noncanonical IGF-1R-Gbetagamma-phospho(T94)Tctex-1 signaling pathway promotes the proliferation of neural progenitors through modulation of ciliary resorption and G1 length.
Title: IGF-1 activates a cilium-localized noncanonical Gβγ signaling pathway that regulates cell-cycle progression.
Data indicate that a decrease in the Gbeta1 production in Ggamma1 knockout rods resulted in a significant reduction in proteasomal overload and caused a striking reversal of photoreceptor degeneration.
Title: Proteasome overload is a common stress factor in multiple forms of inherited retinal degeneration.
ectopically expressed cTalpha 1) forms a heterotrimeric complex with rod Gbeta(1)gamma(1), and substitutes equally for rTalpha in generating photoresponses initiated by either rhodopsin or S-cone opsin
Title: Functional comparison of rod and cone Gα(t) on the regulation of light sensitivity.
Results suggest a model in which the Gbetagamma dimer that is released as a result of the dissociation from Galpha(o) upon activation of mGluR6 closes the TRPM1 channel, perhaps via a direct interaction.
Title: G-protein-mediated inhibition of the Trp channel TRPM1 requires the Gβγ dimer.
WDR26 is a novel Gbetagamma-binding protein that is required for the efficacy of Gbetagamma signaling and leukocyte migration
Title: The WD40 repeat protein WDR26 binds Gβγ and promotes Gβγ-dependent signal transduction and leukocyte migration.
findings demonstrate that transducin betagamma-complex controls signal amplification of the rod phototransduction cascade and is critical for the ability of rod photoreceptors to function in low light conditions.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
