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

rspo3R-spondin-3; Activator of the canonical Wnt signaling pathway by acting as a ligand for lgr4-6 receptors, which acts as a key regulator of angiogenesis. Upon binding to lgr4-6 (lgr4, lgr5 or lgr6), lgr4-6 associate with phosphorylated lrp6 and frizzled receptors that are activated by extracellular Wnt receptors, triggering the canonical Wnt signaling pathway to increase expression of target genes. Acts both in the canonical. Wnt/beta-catenin-dependent pathway and in non-canonical Wnt signaling pathway. Acts as a key regulator of angiogenesis by controlling vascular stability and prunin [...] (317 aa)    
Predicted Functional Partners:
lgr4
Leucine-rich repeat-containing G-protein coupled receptor 4; Receptor for R-spondins that potentiates the canonical Wnt signaling pathway and is involved in the formation of various organs. Upon binding to R-spondins (RSPO1, RSPO2, RSPO3 or RSPO4), associates with phosphorylated LRP6 and frizzled receptors that are activated by extracellular Wnt receptors, triggering the canonical Wnt signaling pathway to increase expression of target genes. In contrast to classical G-protein coupled receptors, does not activate heterotrimeric G-proteins to transduce the signal. Its function as activat [...]

znrf3
E3 ubiquitin-protein ligase znrf3; E3 ubiquitin-protein ligase that acts as a negative regulator of the Wnt signaling pathway by mediating the ubiquitination and subsequent degradation of Wnt receptor complex components. Along with RSPO2 and RNF43, constitutes a master switch that governs limb specification (By similarity). Belongs to the ZNRF3 family.
   
 0.983
rspo2
R-spondin 2_variant1.
  
  
0.913
rspo1
R-spondin-1; Activator of the canonical Wnt signaling pathway by acting as a ligand for lgr4-6 receptors. Upon binding to lgr4-6 (lgr4, lgr5 or lgr6), lgr4-6 associate with phosphorylated lrp6 and frizzled receptors that are activated by extracellular Wnt receptors, triggering the canonical Wnt signaling pathway to increase expression of target genes. Acts both in the canonical Wnt/beta-catenin-dependent pathway and in non-canonical Wnt signaling pathway (By similarity). Belongs to the R-spondin family.

wnt2ba
Protein Wnt; Ligand for members of the frizzled family of seven transmembrane receptors; Belongs to the Wnt family.
   
  
 0.608
porcn
Porcupine O-acyltransferase; Belongs to the membrane-bound acyltransferase family.
      
 0.605
wnt3a
Protein Wnt; Ligand for members of the frizzled family of seven transmembrane receptors; Belongs to the Wnt family.

wrn
WRN RecQ-like helicase.

ctnnb1
Catenin beta-1; Key downstream component of the canonical Wnt signaling pathway (By similarity). 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 and its subsequent degradation by the proteasome (By similarity). 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 (By similarity). Plays a key role in dorso [...]
