Gene Snapshot
G protein α o subunit (Gαo) 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.

Summaries
Gene Group (FlyBase)
HETEROTRIMERIC G-PROTEIN ALPHA SUBUNITS -
The Heterotrimeric G-protein alpha subunits (Gα) can bind guanine nucleotide. When inactive, Gα is bound to GDP and associates with Gβγ forming an heterotrimer. Upon GTP binding, Gα dissociates from the heterotrimer Gαβγ. Gα has an intrinsic guanosine triphosphatase (GTPase) activity. (Adapted from FBrf0209904 and FBrf0183798).
Protein Function (UniProtKB)
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, Galphai and the G-protein coupled receptor, moody, are required in the surface glia to achieve effective insulation of the nerve cord.
(UniProt, P16378)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
Gα47A: G protein α subunit at 47A
Encodes a G protein α subunit that is expressed mainly in the nervous system (DeSousa et al., 1989; Thambi et al., 1989) and shows homology to mammalian Goα. Low levels of this G protein are found in the embryo until completion of germband shortening; then high levels begin to be expressed in the neuropil (Wolfgang, et al., 1990).
Summary (Interactive Fly)
G protein alpha subunit - regulates mesenchymal-epithelial transition that takes place in cardial cells and precursor cells of the visceral musculature

Additional Descriptive Data
Up to stage 13 of embryogenesis, G-oα47A protein is detected only at low levels. After germ band retraction, and through the rest of embryogenesis, G-oα47A protein is detected in the neuropil of the brain and ventral ganglion.
G-oα47A protein is more abundant in heads than bodies. No changes in protein levels were seen in para, sev, ora and norpA mutants. G-oα47A protein levels are decreased in gust mutants and increased in rut, dnc and tur mutants and the over-expression is sex-dependent in the rut mutant.
G-oα47A protein is detected in the neuropil of the brain and the thoracic ganglion, and at lower levels in cortical regions. Some staining was detected in the distal lamina and in the synaptic zone of the lamina. The proximal half of the ocellar nerve, and a bundle of axons in the antennal nerve also stained for G-oα47A protein.

    dsRNA made from templates generated with primers against this gene tested in a cl-8 cell reporter assay to examine any role of G-oα47A in the hh signalling pathway.
    Area matching Drosophila GO protein alpha subunit homolog class II gene, Acc. No. M29602.
    G-oα47A function is required for the formation of the heart, visceral musculature and the nervous system.
    Mutants show defects in the heart, visceral musculature and nervous system.
    Mutation rate at microsatellite loci in 119 lines maintained for approximately 250 generations is estimated to be 6.3x10-6, at least one order of magnitude lower than the mutation rate in mammals.
    Mutant analysis demonstrates G-oα47A is required for embryonic development.
    G proteins belong to a family of membrane-associated guanine nucleotide-binding proteins that couple specific receptors for extracellular signals to specific intracellular effectors, thus regulating the activity of these effectors. When not interacting with the receptor, G proteins are usually in the form of a heterotrimer made up of α, β and γ subunits, with the α subunit bound to GDP. Upon activation by the receptor, the α subunit exchanges GDP for GTP, dissociates from the β-γ subunits and interacts with the effector. Afterwards GTP is hydrolyzed and the heterotrimer of α, β and γ subunits is formed again.
    Identification: Isolated from a genomic library using a bovine αi1 cDNA probe.

    Etymology
    The gene is named "brokenheart" based on the phenotype of mutant embryos.
