Data, including data from studies using transgenic/knockout mice, suggest that Ppp1ca (显示 PPP1CA ELISA试剂盒) and Gnb1 interact in quiescent platelets; then, Ppp1ca (显示 PPP1CA ELISA试剂盒) and Plcb3 (显示 PLCB3 ELISA试剂盒) interact during platelet aggregation; thus, Gnb1 enlists Ppp1ca (显示 PPP1CA ELISA试剂盒) to modulate G protein-coupled receptor (显示 GPR34 ELISA试剂盒) signaling. (Ppp1ca (显示 PPP1CA ELISA试剂盒) = protein phosphatase 1 (显示 PPP1CB ELISA试剂盒), catalytic subunit alpha; Gnb1 = guanine nucleotide-binding protein (显示 TRIM23 ELISA试剂盒), subunit beta-1; Plcb3 (显示 PLCB3 ELISA试剂盒) = phospholipase C (显示 PLC ELISA试剂盒), subunit beta-3)
It was concluded that GIRK2 (显示 KCNJ6 ELISA试剂盒), through its dual responsiveness to G protein beta (显示 GNB3 ELISA试剂盒)-gamma and Na+, mediates a form of neuronal inhibition that is amplifiable in the setting of excess electrical activity.
During corticogenesis, a cilium-transduced, noncanonical IGF-1R (显示 IGF1R ELISA试剂盒)-Gbetagamma-phospho(T94)Tctex-1 (显示 DYNLT1 ELISA试剂盒) signaling pathway promotes the proliferation of neural progenitors through modulation of ciliary resorption and G1 length.
ectopically expressed cTalpha (显示 PCYT1A ELISA试剂盒) 1) forms a heterotrimeric complex with rod Gbeta (显示 SUCLG2 ELISA试剂盒)(1)gamma(1), and substitutes equally for rTalpha in generating photoresponses initiated by either rhodopsin (显示 RHO ELISA试剂盒) or S-cone opsin (显示 RHO ELISA试剂盒)
Results suggest a model in which the Gbetagamma dimer that is released as a result of the dissociation from Galpha(o (显示 GNAO1 ELISA试剂盒)) upon activation of mGluR6 (显示 GRM6 ELISA试剂盒) closes the TRPM1 (显示 TRPM1 ELISA试剂盒) channel, perhaps via a direct interaction.
WDR26 (显示 WDR26 ELISA试剂盒) is a novel Gbetagamma-binding protein that is required for the efficacy of Gbetagamma signaling and leukocyte migration
Our data suggest that the G-protein beta(1)gamma(2) dimer may play an important regulatory role in skeletal muscle excitation-contraction coupling.
G protein subunits beta1 and beta2 have different roles in neutrophil function, as revealed by gene expression silencing in primary mouse neutrophils
G betagamma binds HDAC5 (显示 HDAC5 ELISA试剂盒) and inhibits its transcriptional co-repression activity
G protein betagamma subunits stimulate type V and VI adenylyl cyclases
Through analysis of the genomic and proteomic profiles of resistant cells, we identified an acquired mutation in the GNB1 gene, K89M, as the most likely cause of the resistance
Germline De Novo Mutations in GNB1 Cause Severe Neurodevelopmental Disability, Hypotonia, and Seizures.
we demonstrate a pathogenic role of de novo and autosomal dominant mutations in GNB1 as a cause of Global developmental delay and provide insights how perturbation in heterotrimeric G protein function contributes to the disease
PhLP1 binding stabilizes the Gbeta (显示 SUCLG2 ELISA试剂盒) fold, disrupting interactions with CCT (显示 FLVCR2 ELISA试剂盒) and releasing a PhLP1-Gbeta (显示 SUCLG2 ELISA试剂盒) dimer for assembly with Ggamma.
GNB1 and GNB2 alterations confer transformed and resistance phenotypes across a range of human tumors and may be targetable with inhibitors of G protein signaling.
Data indicate that endogenous mTOR (显示 FRAP1 ELISA试剂盒) interacts with Gbetagamma.
GNB1 plays an important role in the mTOR (显示 FRAP1 ELISA试剂盒)-related anti-apoptosis pathway and can potentially be targeted in the treatment of human breast cancer.
Findings suggest a wide-ranging mechanism by which direct interaction of Gbetagamma with specific chromatin bound transcription factors regulates functional gene networks in response to GPCR (显示 NMUR1 ELISA试剂盒) activation in cells including the angiotensin II type 1 receptor (显示 AGTR1 ELISA试剂盒).
This study provided evidence that GNB1 gene polymorphisms are related to rapid virological response in HCV-1 and HCV-2 (显示 BMPER ELISA试剂盒) infected patients. GNB1 may play an important role in activating the antiviral response prior to treatment.
Gbeta1gamma2-mediated epithelial sodium channel (ENaC (显示 SCNN1A ELISA试剂盒)) inhibition involves activation of phospholipase C-beta (显示 PLCb4 ELISA试剂盒) and its enzymatic products that induce protein kinase C (显示 PKC ELISA试剂盒) and ERK1/2 (显示 MAPK1/3 ELISA试剂盒) signaling pathways.
Data suggest that a hetero-multimer complex forms between light-activated rhodopsin (显示 RHO ELISA试剂盒) and light-activated heterotrimeric transducin (显示 GNAT1 ELISA试剂盒) (T-alpha-1, Gnb1, Gngt1 (显示 GNGT1 ELISA试剂盒)); the stoichiometry is 1:1 rhodopsin:transducin. The complex appears to form on native rod outer segment membranes upon light activation.
The PIP2-induced orientation of the GRK2 (显示 ADRBK1 ELISA试剂盒)-Gbeta1gamma2 complex is therefore most likely caused by specific interactions between PIP2 and the GRK2 (显示 ADRBK1 ELISA试剂盒) PH domain.
determined the crystallographic structure of GRK2 in complex with G protein beta1gamma2 subunits
conclude that GNB1 constitutes over 99% of the GNbeta expressed in bovine rod outer segments and displays structural heterogeneity that is due to post-translational modification, some of which is due to phosphorylation of GNB1.
Heterotrimeric guanine nucleotide-binding proteins (G proteins), which integrate signals between receptors and effector proteins, are composed of an alpha, a beta, and a gamma subunit. These subunits are encoded by families of related genes. This gene encodes a beta subunit. Beta subunits are important regulators of alpha subunits, as well as of certain signal transduction receptors and effectors. This gene uses alternative polyadenylation signals.
