STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

ric8aSynembryn; Guanine nucleotide exchange factor (GEF), which can activate some, but not all, G-alpha proteins independently of G-protein coupled receptors. Acts by exchanging bound GDP for free GTP. Plays a key role in asymmetric spindle positioning, a step for asymmetric cell division that generates cell diversity during development by activating G(i) alpha protein independently of G-protein coupled receptors. In addition to its GEF activity, it plays an essential role in cortical subcellular localization of heterotrimeric G proteins, suggesting it acts as a facilitator of G-alpha funct [...] (573 aa)    
Predicted Functional Partners:
Galphai
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.
   
 
 0.989
Galphao
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.
    
 
 0.963
P5CS
Delta-1-pyrroline-5-carboxylate synthase; Glutamate-5-semialdehyde dehydrogenase activity; glutamate 5-kinase activity; delta1-pyrroline-5-carboxylate synthetase activity. It is involved in the biological process described with: oxidation-reduction process; proline biosynthetic process; In the C-terminal section; belongs to the gamma-glutamyl phosphate reductase family.
      
 0.928
strat
Guanine nucleotide exchange factor MSS4 homolog; Guanine-nucleotide-releasing protein that acts on members of the sec4/ypt1/rab subfamily such as Rab8. During egg development, essential for establishing and maintaining epithelial cell polarity by regulating the correct polarized deposition of basal membrane (BM) proteins such as trol/Pcan and vkg/Coll IV to the basal surface of follicular epithelial (FE) cells. Likely to function by restricting the activity of the vesicle transport regulator Rab8 to the basal membrane, and thus directs BM protein-containing vesicles to the basal side o [...]
   
  
 0.904
Galphas
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.
    
 
 0.898
Gbeta5
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.
    
 
 0.866
cta
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.
   
 
 0.864
RSG7
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.
   
  
 0.859
loco
Regulator of G-protein signaling loco; Acts as a regulator of G protein signaling (RGS). Modulates G protein alpha subunits nucleotide exchange and hydrolysis activities by functioning either as a GTPase-activating protein (GAP), thereby driving G protein alpha subunits into their inactive GDP-bound form, or as a GDP-dissociation inhibitor (GDI). Confers GDI and GAP activities on G(i) alpha subunit Galphai. Confers GAP activity on G(o) alpha subunit Galphao and G(i) alpha subunit Galphai. Involved in the dorsal- ventral axis formation of the egg. Acts as a G-protein signaling for glial [...]

Galphaq
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.
