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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

LACRTExtracellular glycoprotein lacritin; Modulates secretion by lacrimal acinar cells (138 aa)    
Predicted Functional Partners:
CSPG5
Chondroitin sulfate proteoglycan 5; May function as a growth and differentiation factor involved in neuritogenesis. May induce ERBB3 activation
      
 0.903
SDC1
Syndecan-1; Cell surface proteoglycan that bears both heparan sulfate and chondroitin sulfate and that links the cytoskeleton to the interstitial matrix. Regulates exosome biogenesis in concert with SDCBP and PDCD6IP
    
 
 0.796
NID1
Nidogen-1; Sulfated glycoprotein widely distributed in basement membranes and tightly associated with laminin. Also binds to collagen IV and perlecan. It probably has a role in cell- extracellular matrix interactions
    
 
 0.785
VTN
Vitronectin; Vitronectin is a cell adhesion and spreading factor found in serum and tissues. Vitronectin interact with glycosaminoglycans and proteoglycans. Is recognized by certain members of the integrin family and serves as a cell-to-substrate adhesion molecule. Inhibitor of the membrane-damaging effect of the terminal cytolytic complement pathway; Endogenous ligands
    
 
 0.755
FBLN2
Fibulin-2; Its binding to fibronectin and some other ligands is calcium dependent. May act as an adapter that mediates the interaction between FBN1 and ELN; Fibulins
      
 0.747
LCN1
Lipocalin-1; Could play a role in taste reception. Could be necessary for the concentration and delivery of sapid molecules in the gustatory system. Can bind various ligands, with chemical structures ranging from lipids and retinoids to the macrocyclic antibiotic rifampicin and even to microbial siderophores. Exhibits an extremely wide ligand pocket; Belongs to the calycin superfamily. Lipocalin family
      
 0.700
PRR4
Proline-rich protein 4; Proline rich 4
      
 0.691
ZMIZ2
Zinc finger MIZ domain-containing protein 2; Increases ligand-dependent transcriptional activity of AR and other nuclear hormone receptors; Zinc fingers MIZ-type
      
 0.617
FN1
Fibronectin type III domain containing; Endogenous ligands
    
 
 0.591
SERPINB10
Serpin B10; Protease inhibitor that may play a role in the regulation of protease activities during hematopoiesis and apoptosis induced by TNF. May regulate protease activities in the cytoplasm and in the nucleus; Serpin peptidase inhibitors
      
 0.546
