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

smoProtein smoothened; Segment polarity protein required for correct patterning of every segment. G protein-coupled receptor that associates with the patched protein (ptc) to transduce the hedgehog (hh) signal through the activation of an inhibitory G-protein. In the absence of hh, ptc represses the constitutive signaling activity of smo through fused (fu). Essential component of a hh-signaling pathway which regulates the Duox-dependent gut immune response to bacterial uracil; required to activate Cad99C-dependent endosome formation, norpA-dependent Ca2+ mobilization and p38 MAPK, which a [...] (1036 aa)    
Predicted Functional Partners:
cos
Kinesin-like protein costa; Regulates cubitus interruptus (ci) processing by recruiting multiple kinases to promote its efficient phosphorylation. Scaffolds multiple kinases and ci into proximity to promote its hyperphosphorylation, which then targets it for SCFSlimb/proteasome- mediated processing to generate its repressor form. Hh signaling inhibits ci phosphorylation by interfering with the cos-ci-kinases complex formation. Negatively regulates hh-signaling pathways during various processes, including photoreceptor differentiation. May negatively regulate a hh- signaling pathway whi [...]

ptc
Protein patched; Segmentation polarity protein. Acts as a receptor for the hedgehog protein (HH). Associates with the smoothened protein (SMO) to transduce the hedgehog signal leading to the activation of wingless, decapentaplegic and patched itself. Participates in cell interactions that establish pattern within the segment and the imaginal disks during development. In the absence of HH, represses the constitutive signaling activity of smo through fused (FU).
    
 0.999
Su(fu)
Suppressor of fused (Su(fu)) encodes a negative regulator of the Hedgehog signaling pathway. It forms a complex with the transcription factor encoded by ci to inhibit its activity; Belongs to the SUFU family.
   
 
 0.997
hh
Protein hedgehog C-product; Intercellular signal essential for a variety of patterning events during development. Establishes the anterior-posterior axis of the embryonic segments and patterns the larval imaginal disks. Binds to the patched (ptc) receptor, which functions in association with smoothened (smo), to activate the transcription of target genes wingless (wg), decapentaplegic (dpp) and ptc. In the absence of hh, ptc represses the constitutive signaling activity of smo through fused (fu). Essential component of a signaling pathway which regulates the Duox-dependent gut immune r [...]

Pka-C1
cAMP-dependent protein kinase catalytic subunit 1; Serine/threonine-protein kinase involved in memory formation. Promotes long-term memory by phosphorylating meng and by regulating CrebB protein stability and activity. As part of ethanol response in the glia, mediates ethanol-induced structural remodeling of actin cytoskeleton and perineurial membrane topology when anchored to the membrane.
   
 0.996
Gprk2
G protein-coupled receptor kinase 2 (Gprk2) encodes a member of a family of serine/threonine kinases that modulate G-protein coupled receptors. It is required for female fertility, normal egg shape, and normal egg cAMP levels. It is also implicated in Hedgehog signaling and olfactory rhythmicity; Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. GPRK subfamily.
   
 0.995
Pka-C2
ATP binding; protein serine/threonine kinase activity; cAMP-dependent protein kinase activity; protein kinase A regulatory subunit binding. It is involved in the biological process described with: protein kinase A signaling; peptidyl-serine phosphorylation.
     
 0.985
ci
Transcriptional activator cubitus interruptus; Has a dual function as a transcriptional activator and a repressor of the hedgehog (Hh) pathway. The full-length ci form (ciFL), acts as an activator (ciA) while ciR, its C-terminally truncated form, acts as a repressor. Involved in segment polarity. Required for the normal development of the posterior half of each embryonic segment. Engrailed protein directly represses ci expression in posterior compartment cells. Essential component of a hh-signaling pathway which regulates the Duox-dependent gut immune response to bacterial uracil; requ [...]
   
 0.981
fu
Serine/threonine-protein kinase fused; Probable serine/threonine-protein kinase; maternally required for correct patterning in the posterior part of each embryonic metamere. May be involved in control of cell division during metamorphosis and ovarian development. May interact with costal-2.
   
 0.962
krz
Kurtz, isoform A; Kurtz (krz) encodes a beta-arrestin (non-visual arrestin) involved in the desensitization and endocytic internalization of G protein coupled receptors, thus downregulating their activity. It also controls other signaling pathways, including Notch, receptor tyrosine kinase, Hedgehog, and Toll. It is required maternally for normal embryonic patterning and zygotically for larval viability.
