The G-protein α subunit GhGPA positively regulates Gossypium hirsutum resistance to Verticillium dahliae via induction of SA and JA signaling pathways and ROS accumulation

Crop Journal, 2021
Verticillium wilt, a devastating disease in cotton caused by Verticillium dahliae, reduces cotton quality and yield. Heterotrimeric GTP-binding proteins, consisting of Gα, Gβ, and Gγ subunits, transducers of receptor signaling, function in a wide range ...

Characterisation of Bombyx mori odorant-binding proteins reveals that a general odorant-binding protein discriminates between sex pheromone components [PDF]

, 2009
In many insect species, odorant-binding proteins (OBPs) are thought to be responsible for the transport of pheromones and other semiochemicals across the sensillum lymph to the olfactory receptors (ORs) within the antennal sensilla.

Dopamine D2L receptor-interacting proteins regulate dopaminergic signaling

Journal of Pharmacological Sciences, 2017
Dopamine receptor family proteins include seven transmembrane and trimeric GTP-binding protein-coupled receptors (GPCRs). Among them, the dopamine D2 receptor (D2R) is most extensively studied.

A P-loop mutation in Gα subunits prevents transition to the active state: implications for G-protein signaling in fungal pathogenesis.

PLoS Pathogens, 2012
Heterotrimeric G-proteins are molecular switches integral to a panoply of different physiological responses that many organisms make to environmental cues.

Structure and function of bacterial dynamin-like proteins [PDF]

, 2012
Membrane dynamics are essential for numerous cellular processes in eukaryotic and prokaryotic cells. In eukaryotic cells, membrane fusion and fission are often catalyzed by large GTPases of the dynamin protein family. These proteins couple GTP hydrolysis

A method for the prediction of GPCRs coupling specificity to G-proteins using refined profile Hidden Markov Models

BMC Bioinformatics, 2005
Background G- Protein coupled receptors (GPCRs) comprise the largest group of eukaryotic cell surface receptors with great pharmacological interest. A broad range of native ligands interact and activate GPCRs, leading to signal transduction within cells.

The activation mechanism of Irga6, an interferon-inducible GTPase contributing to mouse resistance against Toxoplasma gondii [PDF]

, 2011
Background: The interferon-inducible immunity-related GTPases (IRG proteins/p47 GTPases) are a distinctive family of GTPases that function as powerful cell-autonomous resistance factors.

Small GTP-binding proteins of squid photoreceptor Interaction with photoactivated rhodopsin [PDF]

, 1994
Squid photoreceptor membranes contain several small GTP-binding proteins (22–27 kDa) in addition to heterotrimeric G-proteins. In addition, these membranes contain several proteins which can be ADP-ribosylated by exoenzyme C3 from Clostridiumbotulinum ...
