Heterotrimeric G protein subunit Gγ13 is critical to olfaction.
The activation of G-protein-coupled olfactory receptors on the olfactory sensory neurons (OSNs) triggers a signaling cascade, which is mediated by a heterotrimeric G-protein consisting of α, β, and γ subunits. Although its α subunit, Gαolf, has been identified and well characterized, the identities of its β and γ subunits and their function in olfactory signal transduction, however, have not be...
متن کاملThe heterotrimeric G protein alpha subunit acts upstream of the small GTPase Rac in disease resistance of rice.
We used rice dwarf1 (d1) mutants lacking a single-copy Galpha gene and addressed Galpha's role in disease resistance. d1 mutants exhibited a highly reduced hypersensitive response to infection by an avirulent race of rice blast. Activation of PR gene expression in the leaves of the mutants infected with rice blast was delayed for 24 h relative to the wild type. H(2)O(2) production and PR gene e...
متن کاملRice dwarf mutant d1, which is defective in the alpha subunit of the heterotrimeric G protein, affects gibberellin signal transduction.
Previously, we reported that the rice dwarf mutant, d1, is defective in the alpha subunit of the heterotrimeric G protein (Galpha). In the present study, gibberellin (GA) signaling in d1 and the role of the Galpha protein in the GA-signaling pathway were investigated. Compared with the wild type, GA induction of alpha-amylase activity in aleurone cells of d1 was greatly reduced. Relative to the...
متن کامل5 - Hydroxytryptamine 4 ( a ) Receptor Is Coupled to the G Subunit of Heterotrimeric G 13 Protein
Serotonin (5-hydroxytryptamine (5-HT)) is an important neurotransmitter that regulates multiple events in the central nervous system. Many of the 5-HT functions are mediated via G protein-coupled receptors that are coupled to multiple heterotrimeric G proteins, including Gs, Gi, and Gq subfamilies (Martin, G. R., Eglen, R. M., Hamblin, M. W., Hoyer, D., and Yocca, F. (1998) Trends Pharmacol. Sc...
متن کاملBlunted apoptosis of erythrocytes in mice deficient in the heterotrimeric G-protein subunit Gαi2
Putative functions of the heterotrimeric G-protein subunit Gαi2-dependent signaling include ion channel regulation, cell differentiation, proliferation and apoptosis. Erythrocytes may, similar to apoptosis of nucleated cells, undergo eryptosis, characterized by cell shrinkage and cell membrane scrambling with phosphatidylserine (PS) exposure. Eryptosis may be triggered by increased cytosolic Ca...
