G protein alpha o subunit (Galphao) encodes the most abundant G protein in the nervous tissue and is involved in signaling by a variety of GPCRs. It contributes to heart development, axonogenesis, neuro-muscular junction formation, asymmetric cell division, planar cell polarity, blood-brain barrier establishment, Wnt signaling, and gustatory and olfactory sensory perception; Belongs to the G-alpha family. G(i/o/t/z) subfamily.

G protein alpha s subunit (Galphas) encodes an alpha subunit of the class of heterotrimeric G proteins, found on the cytosolic face of the plasma membrane. An inactive GDP-bound form forms a heterotrimer with beta and gamma subunits. On activation by a 7-TM receptor, the product of Galphas exchanges GDP for GTP, dissociates from the trimer, and activates adenylyl cyclase, thus initiating cAMP signaling. Galphas roles include neurophysiology, and behaviors including learning; Belongs to the G-alpha family. G(s) subfamily.

Guanine nucleotide-binding protein subunit beta-2; G protein beta-subunit 76C (Gbeta76C) encodes a protein that forms a Gbeta-gamma complex that is anchored to the plasma membrane via lipid modification of the gamma-subunit. The Gbeta-gamma complex plays an essential role in phototransduction by presenting the Gqalpha-subunit to rhodopsin GPCRs for efficient activation, and preventing spontaneous GDP-GTP exchange on the Gqalpha-subunit.

Guanine nucleotide-binding protein subunit gamma-e; Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction. This subunit functions in visual transduction in the compound eye.

RH17413p; GTPase activator activity; G-protein gamma-subunit binding. It is involved in the biological process described with: G protein-coupled receptor signaling pathway; dopamine receptor signaling pathway; positive regulation of GTPase activity.

Guanine nucleotide-binding protein subunit alpha homolog; May play a role in a signal transduction pathway used during gastrulation. Required specifically for the ventral furrow and posterior midgut invaginations, where it is necessary for coordinating cell shape changes; Belongs to the G-alpha family. G(12) subfamily.

G protein alpha q subunit; Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. Could be the transducin analog, an amplifier and one of the transducers of a visual impulse that performs the coupling between opsin and cGMP-phosphodiesterase. Could mediate a subset of olfactory and gustatory responses.

G protein alpha i subunit; Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. Plays a role in glial cell differentiation during embryogenesis; loco, Galphao and the G-protein coupled receptor, moody, are required in the surface glia to achieve effective insulation of the nerve cord; Belongs to the G-alpha family. G(i/o/t/z) subfamily.

G protein alpha f subunit (Galphaf) encodes a transcriptional target of the JAK/STAT pathway in blood cells where it regulates cell shape and function; Belongs to the G-alpha family.
