Summary: Predicted to enable G protein-coupled receptor binding activity; G-protein beta/gamma-subunit complex binding activity; and GTPase activity. Involved in several processes, including positive regulation of feeding behavior; response to trehalose; and sensory perception of sweet taste. Located in basement membrane and plasma membrane. Part of heterotrimeric G-protein complex. Is active in neuromuscular junction; postsynapse; and presynapse. Is expressed in several structures, including chemosensory sensory organ; embryonic/larval midgut primordium; gut section; larval muscle cell; and organism subdivision. Human ortholog(s) of this gene implicated in several diseases, including ACTH-independent macronodular adrenal hyperplasia 1; dystonia 25; pituitary adenoma 3; progressive osseous heteroplasia; and pseudohypoparathyroidism (multiple). Orthologous to several human genes including GNAL (G protein subunit alpha L). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

This study observed an unexpected and significant Galphas -dependent increase in cAMP levels in response to strong Smo activation in Smo-transfected cells.
Title: Activation of Smoothened in the Hedgehog pathway unexpectedly increases Gα(s)-dependent cAMP levels in Drosophila.
dgsR60 mutant synaptic transmission defects were caused predominantly by lack of Gs(alpha) in presynaptic neurons and not in postsynaptic muscles
Title: Presynaptic impairment of synaptic transmission in Drosophila embryos lacking Gs(alpha).
DGsalpha is involved in trehalose perception. We suggest that sugar-taste signals are processed through the Gsalpha-mediating signal transduction pathway in sugar-sensitive GRNs in Drosophila.
Title: Gsalpha is involved in sugar perception in Drosophila melanogaster.
