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

Dkk1Dickkopf WNT signaling pathway inhibitor 1. (270 aa)    
Predicted Functional Partners:
Lrp5
Low-density lipoprotein receptor-related protein; Component of the Wnt-Fzd-LRP5-LRP6 complex that triggers beta-catenin signaling through inducing aggregation of receptor-ligand complexes into ribosome-sized signalsomes. Belongs to the LDLR family.
    
 
 0.999
Lrp6
Low-density lipoprotein receptor-related protein; Component of the Wnt-Fzd-LRP5-LRP6 complex that triggers beta-catenin signaling through inducing aggregation of receptor-ligand complexes into ribosome-sized signalsomes. Belongs to the LDLR family.
    
 
 0.999
Kremen1
Kremen protein 1; Receptor for Dickkopf proteins. Cooperates with DKK1/2 to inhibit Wnt/beta-catenin signaling by promoting the endocytosis of Wnt receptors LRP5 and LRP6. In the absence of DKK1, potentiates Wnt-beta- catenin signaling by maintaining LRP5 or LRP6 at the cell membrane. Can trigger apoptosis in a Wnt-independent manner and this apoptotic activity is inhibited upon binding of the ligand DKK1. Plays a role in limb development; attenuates Wnt signaling in the developing limb to allow normal limb patterning and can also negatively regulate bone formation. Modulates cell fate [...]

Kremen2
Kremen protein; Receptor for Dickkopf proteins. Cooperates with DKK1/2 to inhibit Wnt/beta-catenin signaling by promoting the endocytosis of Wnt receptors LRP5 and LRP6.
    
 
 0.989
Sost
Sclerostin; Negative regulator of bone growth that acts through inhibition of Wnt signaling and bone formation; Belongs to the sclerostin family.
      
 0.925
Ctnnb1
Catenin beta-1; Key downstream component of the canonical Wnt signaling pathway. In the absence of Wnt, forms a complex with AXIN1, AXIN2, APC, CSNK1A1 and GSK3B that promotes phosphorylation on N-terminal Ser and Thr residues and ubiquitination of CTNNB1 via BTRC and its subsequent degradation by the proteasome. In the presence of Wnt ligand, CTNNB1 is not ubiquitinated and accumulates in the nucleus, where it acts as a coactivator for transcription factors of the TCF/LEF family, leading to activate Wnt responsive genes. Involved in the regulation of cell adhesion, as component of an [...]
   
 
 0.878
Wnt2
Protein Wnt; Ligand for members of the frizzled family of seven transmembrane receptors; Belongs to the Wnt family.
    
 
 0.867
Sfrp2
Secreted frizzled-related protein 2.
   
 
 0.847
Wnt3a
Protein Wnt; Ligand for members of the frizzled family of seven transmembrane receptors; Belongs to the Wnt family.
    
 
 0.821
Wnt1
Protein Wnt; Ligand for members of the frizzled family of seven transmembrane receptors; Belongs to the Wnt family.
