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

HCAR1Hydroxycarboxylic acid receptor 1; Belongs to the G-protein coupled receptor 1 family. (333 aa)    
Predicted Functional Partners:
EDN1
Big endothelin-1; Endothelins are endothelium-derived vasoconstrictor peptides (By similarity). Probable ligand for G-protein coupled receptors EDNRA and EDNRB which activates PTK2B, BCAR1, BCAR3 and, GTPases RAP1 and RHOA cascade in glomerular mesangial cells (By similarity). Belongs to the endothelin/sarafotoxin family.
    
  0.840
EDN3
Endothelin 3.
    
  0.839
GNAI2
Guanine nucleotide-binding protein G(i) subunit alpha-2; Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. The G(i) proteins are involved in hormonal regulation of adenylate cyclase: they inhibit the cyclase in response to beta- adrenergic stimuli. May play a role in cell division (By similarity). Belongs to the G-alpha family. G(i/o/t/z) subfamily.
    
  0.825
OXT
Oxytocin/neurophysin I prepropeptide; Belongs to the vasopressin/oxytocin family.
   
  0.816
GHRL
Ghrelin and obestatin prepropeptide.
    
  0.813
SST
Somatostatin.
    
  0.812
NPY
Neuropeptide Y; NPY is implicated in the control of feeding and in secretion of gonadotrophin-release hormone; Belongs to the NPY family.
    
 0.810
AVP
Vasopressin-neurophysin 2-copeptin; Neurophysin 2 specifically binds vasopressin; Belongs to the vasopressin/oxytocin family.
   
  0.774
GNAI3
Guanine nucleotide-binding protein G(i) subunit alpha; Heterotrimeric guanine nucleotide-binding proteins (G proteins) function as transducers downstream of G protein-coupled receptors (GPCRs) in numerous signaling cascades. The alpha chain contains the guanine nucleotide binding site and alternates between an active, GTP-bound state and an inactive, GDP-bound state. Signaling by an activated GPCR promotes GDP release and GTP binding. The alpha subunit has a low GTPase activity that converts bound GTP to GDP, thereby terminating the signal. Both GDP release and GTP hydrolysis are modul [...]
