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

CkIalphaCasein kinase I isoform alpha; Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. Can phosphorylate a large number of proteins. Negative regulator of wg signaling. Phosphorylates arm directly or indirectly and stimulates its degradation which prevents inappropriate wg signaling. Phosphorylates smo which promotes its accumulation at the cell surface and its signaling activity in response to hh. Together with dco, regulates proteolytic processing of ci by phosphorylating it which promotes its binding to slmb, the F [...] (337 aa)    
Predicted Functional Partners:
Axn
Axin (Axn) encodes the key scaffolding protein for the canonical Wnt signalling pathway. In the absence of signal, it targets the product of arm for proteolysis inhibiting Wnt signalling. In the presence of signal, it forms a part of the membrane activation complex, disrupting the product of arm degradation. This pathway play roles in cell proliferation (imaginal disc), differentiation (embryonic patterning), death and stemness.

arm
Armadillo segment polarity protein; Isoform neural may associate with CadN and participate in the transmission of developmental information. Can associate with alpha- catenin. Isoform cytoplasmic accumulates through wg signaling; arm function in wg signal transduction is required early in development for determination of neuroblast fate. Arm and Abl proteins function cooperatively at adherens junctions in both the CNS and epidermis. Belongs to the beta-catenin family.
   
 0.975
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 [...]
   
 0.967
sgg
Protein kinase shaggy; Required for several developmental events such as syncytial blastoderm formation and embryonic segmentation. Is involved in transcriptional regulation. Required for arm phosphorylation. Wg signaling operates by inactivating the sgg repression of en autoactivation. Negatively controls the neuromuscular junction (NMJ) growth in presynaptic motoneurons. Plays a role in the regulation of microtubule dynamics and actin cytoskeleton during embryogenesis. Required for phosphorylation of sra in activated eggs. Essential for completion of meiosis, possibly by triggering c [...]
   
 0.957
smo
Protein 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 [...]
   
 
 0.951
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 [...]
    
 0.948
dco
Discs overgrown protein kinase; Involved in circadian rhythms, viability and molecular oscillations of the clock genes period (per) and timeless (tim). Dbt reduces the stability and thus the accumulation of monomeric per proteins, probably through phosphorylation. No evident circadian oscillation is detected in head. Together with CkIalpha, regulates processing of ci by phosphorylating it which promotes its binding to slmb, the F-box recognition component of the SCF(slmb) E3 ubiquitin- protein ligase.
  
0.931
dsh
Segment polarity protein dishevelled; Required to establish coherent arrays of polarized cells and segments in embryos. Plays a role in wingless (wg) signaling, possibly through the reception of the wg signal by target cells and subsequent redistribution of arm protein in response to that signal in embryos. This signal seems to be required to establish planar cell polarity and identity.
   
 
 0.926
slmb
Supernumerary limbs (slmb) encodes an essential, conserved F-box protein and a component of the SCF (Skp/Cullin/F-box) E3 ubiquitin-ligase, providing substrate specificity to the SCF. It negatively regulates multiple signaling pathways and cellular processes by promoting the proteasome-mediated degradation or cleavage of its targets, including the products of arm and ci (Wg and Hh signaling), SAK, per and Cap-H2.
   
 0.925
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.
