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

SmurfE3 ubiquitin-protein ligase Smurf1; E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Down-regulates Dpp signaling after gastrulation by promoting MAD ubiquitination and subsequent degradation. (1061 aa)    
Predicted Functional Partners:
Smox
Mothers against decapentaplegic homolog; Smad on X (Smox) encodes the primary transcription factor that mediates Activin signalling. Upon phosphorylation by the receptor encoded by babo, it forms a complex with the co-Smad protein encoded by Med. This complex translocates to the nucleus where it regulates expression of target genes.
    
 0.995
Dad
Mothers against decapentaplegic homolog; Daughters against dpp (Dad) encodes the inhibitory SMAD in the BMP/Dpp pathway. It is involved in growth regulation and developmental patterning.
    
 0.994
Med
Mothers against decapentaplegic homolog; Medea (Med) encodes a protein that belongs to the highly conserved Smad family. It can bind its siblings encoded by Mad or Smox to facilitate signal transduction for the product of dpp or Activin ligands in the TGF-beta family. Med-complexes function as transcriptional regulators. Many developmental roles include dorsal-ventral patterning, patterning and proliferation of the wing disc and gene expression in the mushroom body of the larval brain.
   
 0.986
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).
    
 0.983
Traf6
TNF-receptor-associated factor 6 (Traf6) encodes a protein that belongs to a family of adaptor proteins involved in transducing downstream signaling by interacting with cell surface receptors. It mediates the pro-inflammatory effects of Toll and related receptor signaling, and the cell death induced by JNK activation via the product of egr.
   
 0.959
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.
   
 0.956
Mad
Mothers against dpp (Mad) encodes the primary transcription factor that mediates cellular response to the BMP like ligands encoded by dpp, scw and gbb. Upon phosphorylation by either the products of sax or tkv (type I BMP receptors), it forms a complex with the product of Med and translocates to the nucleus where, together with cofactors, it regulates expression of BMP response target genes; Belongs to the dwarfin/SMAD family.
   
 0.948
Cbl
Cbl proto-oncogene (Cbl) encodes an E3 protein-ubiquitin ligase for protein post-translational modification in RTK signaling (EGFR, VEGFR, FGF, and RET families) and non-RTK signaling (Src family). After the ubiquitination mediated by the product of Cbl, the substrates will be targeted to protein degradation for controlling cell growth, survival, migration and inflammation.

RpL40
Ubiquitin-60S ribosomal protein L40; [Ubiquitin]: exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is invol [...]

RpS27A
Ubiquitin-40S ribosomal protein S27a; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains).
