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.

Latrophilin Cirl; Latrotoxin receptor activity; G protein-coupled receptor activity; carbohydrate binding; Belongs to the G-protein coupled receptor 2 family. LN-TM7 subfamily.

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.

Regulator of G-protein signaling 7, isoform A; It is involved in the biological process described with: regulation of G protein-coupled receptor signaling pathway; intracellular signal transduction.

Uncharacterized protein, isoform B; It is involved in the biological process described with: intracellular signal transduction; G protein-coupled receptor signaling pathway.

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.

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.

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.

SD21019p; GTPase activity; G protein-coupled receptor binding; guanyl nucleotide binding; G-protein beta/gamma-subunit complex binding. It is involved in the biological process described with: adenylate cyclase-modulating G protein-coupled receptor signaling pathway; phospholipase C-activating dopamine receptor signaling pathway.
