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

C1QAComplement C1q subcomponent subunit A; C1q associates with the proenzymes C1r and C1s to yield C1, the first component of the serum complement system. The collagen-like regions of C1q interact with the Ca(2+)-dependent C1r(2)C1s(2) proenzyme complex, and efficient activation of C1 takes place on interaction of the globular heads of C1q with the Fc regions of IgG or IgM antibody present in immune complexes. (266 aa)    
Predicted Functional Partners:
C1QC
Complement C1q subcomponent subunit C isoform 1.
  
0.999
C1QB
Complement C1q B chain.
   
0.998
SERPING1
Plasma protease C1 inhibitor isoform X1; Belongs to the serpin family.
   
 0.971
C4A
Uncharacterized protein.
   
 
 0.936
C2
Uncharacterized protein; Belongs to the peptidase S1 family.
   
 0.924
CALR
Calreticulin; Calcium-binding chaperone that promotes folding, oligomeric assembly and quality control in the endoplasmic reticulum (ER) via the calreticulin/calnexin cycle. This lectin interacts transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER. Interacts with the DNA-binding domain of NR3C1 and mediates its nuclear export (By similarity). Involved in maternal gene expression regulation. May participate in oocyte maturation via the regulation of calcium homeostasis; Belongs to the calreticulin family.

CSF1R
Colony stimulating factor 1 receptor.
   
  
 0.909
VSIG4
V-set and immunoglobulin domain containing 4.
   
  
 0.898
TREM2
Ig-like domain-containing protein.
   
  
 0.859
TYROBP
TYRO protein tyrosine kinase-binding protein; Adapter protein which non-covalently associates with activating receptors found on the surface of a variety of immune cells to mediate signaling and cell activation following ligand binding by the receptors (By similarity). TYROBP is tyrosine-phosphorylated in the ITAM domain following ligand binding by the associated receptors which leads to activation of additional tyrosine kinases and subsequent cell activation (By similarity). Also has an inhibitory role in some cells (By similarity). Non-covalently associates with activating receptors [...]
