A Peptide Core Motif for Binding to Heterotrimeric G Protein α Subunits [PDF]

open access: yes, 2005
Recently, in vitro selection using mRNA display was used to identify a novel peptide sequence that binds with high affinity to G{alpha}i1. The peptide was minimized to a 9-residue sequence (R6A-1) that retains high affinity and specificity for the GDP ...

Multi-Omics Analysis of Multiple Glucose-Sensing Receptor Systems in Yeast

open access: yesBiomolecules, 2022
The yeast Saccharomyces cerevisiae has long been used to produce alcohol from glucose and other sugars. While much is known about glucose metabolism, relatively little is known about the receptors and signaling pathways that indicate glucose availability.

Inhibition of Subsets of G Protein-coupled Receptors by Empty Mutants of G Protein α Subunits in Go, G11, and G16 [PDF]

open access: yes, 2000
We previously reported that the xanthine nucleotide binding Goα mutant, GoαX, inhibited the activation of Gi-coupled receptors. We constructed similar mutations in G11α and G16α and characterized their nucleotide binding and receptor interaction.

Calcium-independent inhibitory G-protein signaling induces persistent presynaptic muting of hippocampal synapses [PDF]

open access: yes, 2011
Adaptive forms of synaptic plasticity that reduce excitatory synaptic transmission in response to prolonged increases in neuronal activity may prevent runaway positive feedback in neuronal circuits.

Crystal structure of rhodopsin bound to arrestin by femtosecond X-ray laser. [PDF]

open access: yes, 2015
G-protein-coupled receptors (GPCRs) signal primarily through G proteins or arrestins. Arrestin binding to GPCRs blocks G protein interaction and redirects signalling to numerous G-protein-independent pathways.

G Protein Trafficking [PDF]

open access: yes, 2012
The classical view of heterotrimeric G protein signaling places G -proteins at the cytoplasmic surface of the cell's plasma membrane where they are activated by an appropriate G protein-coupled receptor. Once activated, the GTP-bound Gα and the free Gβγ are able to regulate plasma membrane-localized effectors, such as adenylyl cyclase, phospholipase C ...

Role of G{alpha}12 and G{alpha}13 as Novel Switches for the Activity of Nrf2, a Key Antioxidative Transcription Factor [PDF]

open access: yes, 2007
G{alpha}12 and G{alpha}13 function as molecular regulators responding to extracellular stimuli. NF-E2-related factor 2 (Nrf2) is involved in a protective adaptive response to oxidative stress.

The G protein γ subunit SlGGC1 regulates saline-alkali stress response in tomato

open access: yesVegetable Research
Saline-alkali stress poses a severe threat to crop yield and quality. While significant progress has been achieved in elucidating the mechanisms of plant resistance to salt stress, the molecular underpinnings governing plant responses to saline-alkali ...

Mycobacterium tuberculosis CarD, an essential global transcriptional regulator forms amyloid-like fibrils

open access: yesScientific Reports, 2018
CarD is an essential global transcription regulator from Mycobacterium tuberculosis (Mtb) that binds RNA polymerase and activates transcription by stabilizing the transcription initiation complex.
