Gnai1 function is impaired in the spinal cord of Ews/Ewsr1 (show EWSR1 ELISA Kits) KO mice
LGN (show GPSM2 ELISA Kits) and Galphai participate in a long-inferred signal that originates outside the bundle to model its staircase-like architecture, a property that is essential for direction sensitivity to mechanical deflection and hearing.
stimulation of GPR17 (show GPR17 ELISA Kits) by the small molecule agonist MDL29,951 (2-carboxy-4,6-dichloro-1H-indole-3-propionic acid) decreases myelin basic protein (show MBP ELISA Kits) expression levels mainly by triggering the Galphai/o signaling pathway.
Gnai1 missense mutation is responsible of hyperpigmentation in mouse model.
acidosis in inflamed tissues may be a decisive factor to regulate switching of PKA and PKCepsilon dependence via proton-sensing G-protein-coupled receptors.
Data show that guanine nucleotide-binding protein G(i) subunit alpha-1 and alpha-3 (Galphai1/3) can interact with CD14 antigen/Grb2-associated binding protein Gab1, which modulates macrophage polarization in vitro and in vivo.
By using mice deficient in individual Galphai/o G-protein subunits, authors demonstrate that Galphai1 and Galphai3 are the critical in vivo targets of ADP-ribosylation underlying vasoactive amine sensitization elicited by pertussis toxin exposure.
leucine can directly facilitate insulin (show INS ELISA Kits) signaling through a Galphai protein-dependent intracellular signaling pathway
Inactive Galpha(i1)-GDP enhances the affinity of RGS14 for H-Ras-GTP in live cells, resulting in a ternary signaling complex that is further regulated by G protein-coupled receptors.
Mice with mutations of Gnai1 or Gnai2 (show GNAI2 ELISA Kits) have neither fusions of ribs nor lumbar vertebrae, but loss of both Gnai3 (show GNAI3 ELISA Kits) and one of the other two genes increases the number and severity of rib fusions without affecting the lumbar fusions.
These data indicate that, unlike in taste cells, TAS2Rs couple to the prevalent G proteins, Galphai1, Galphai2 (show GNAI2 ELISA Kits), and Galphai3 (show GNAI3 ELISA Kits), with no evidence for functional coupling to Galphagust.
testosterone rapidly increased whole-cell HCAEC SKCa and BKCa (show KCNMA1 ELISA Kits) currents via a surface androgen receptor (show AR ELISA Kits), Gi/o protein, and protein kinase A
These findings suggest that Gi1 interacts only with active GPCRs and that the well known high speed of GPCR signal transduction does not require preassembly between G proteins and GPCRs.
CGRP (show S100A12 ELISA Kits) family of receptors displays both ligand- and RAMP-dependent signaling bias among the Galphas (show GNAS ELISA Kits), Galphai, and Galphaq (show GNAQ ELISA Kits)/11 pathways.
biochemical and computational data indicate that the interactions between alpha5, alpha1, and beta2-beta3 are not only vital for GDP release during G protein activation, but they are also necessary for proper GTP binding (show RND2 ELISA Kits) (or GDP rebinding).
Data indicate that hydroxyurea (HU) induces SAR1 (show IQGAP1 ELISA Kits) protein expression, which in turn activates gamma-globin (show HBG1 ELISA Kits) expression, predominantly through the Gialpha/JNK (show MAPK8 ELISA Kits)/Jun (show JUN ELISA Kits) pathway.
Gi alpha subunit (show POLG ELISA Kits) was found to be a key modulator of GABAB-receptors signaling in analgesia.
AC5, by binding active Galphai1, interferes with G-protein deactivation and reassembly and thereby might sensitize its own regulation.
Data indicate that focal adhesion kinase (FAK) activation and cell migration require Src, Gi/Go, COX-2 and LOXs activities.
resistin (show RETN ELISA Kits) contributes to the pro-inflammatory state of SMC (show DYM ELISA Kits) by the up-regulation of CX3CL1 (show CX3CL1 ELISA Kits) and CX3CR1 (show CX3CR1 ELISA Kits) expression via a mechanism involving NF-kB, AP-1 (show FOSB ELISA Kits), and STAT1 (show STAT1 ELISA Kits)/3 transcription factors, (2) resistin (show RETN ELISA Kits) employs TLR4 (show TLR4 ELISA Kits) and Gi-protein signaling.
Guanine nucleotide binding proteins are heterotrimeric signal-transducing molecules consisting of alpha, beta, and gamma subunits. The alpha subunit binds guanine nucleotide, can hydrolyze GTP, and can interact with other proteins. The protein encoded by this gene represents the alpha subunit of an inhibitory complex. The encoded protein is part of a complex that responds to beta-adrenergic signals by inhibiting adenylate cyclase. Two transcript variants encoding different isoforms have been found for this gene.
