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

drprProtein draper; Receptor which is involved in the phagocytosis of a variety of cells including apoptotic cells, severed and pruned axons, degenerating dendrites, salivary gland cells, germline cells and bacteria. Binds to the ligand prtp which relocates from the endoplasmic reticulum to the cell surface during apoptosis. Ligand-binding may promote tyrosine phosphorylation mediated by Src42a, interaction with shark and subsequent activation of phagocytosis. Also binds to the membrane phospholipid phosphatidylserine which is exposed on the surface of apoptotic cells. Required for the pha [...] (1042 aa)    
Predicted Functional Partners:
ced-6
PTB domain-containing adapter protein ced-6; Plays a role in axon pruning in larval mushroom body neurons during metamorphosis. Plays a role in the infiltration of glial cell processes into mushroom body lobes and the subsequent engulfment of degenerating axon branches. Involved in Drpr-mediated phagocytosis of apoptotic cells. Required for bacterial phagocytosis. During neuromuscular junction development, required for the clearance of pruned ghost boutons and presynaptic debris and for normal synaptic growth.
   
 
 0.968
Shark
Tyrosine-protein kinase Shark; Following axon injury, required for recruitment of drpr and glial cells to severed axons and for glial clearance of severed axons from the central nervous system. Together with Src42a and drpr, promotes the migration of macrophages to sites of wounding as part of a signaling cascade where Scr42a detects production of hydrogen peroxide at wound sites which triggers phosphorylation of drpr and subsequent recruitment and activation of shark. May be involved in signal transduction on the apical surface of ectodermal epithelial cells, regulating their polarity [...]

Ced-12
Ced-12 (Ced-12) encodes a protein that functions with Dock family members (encoded by mbc or spg) to regulate GTPase activity. It contributes to myoblast fusion, apoptotic cell engulfment, cell migration, and embryonic cellularization.
   
 
 0.938
dpy
Dumpy, isoform Q; Dumpy (dpy) encodes an extracellular protein involved in epidermal-cuticle attachment, aposition of wing surfaces and trachea development.
     
 
0.900
prtp
Thioredoxin domain-containing protein 5 homolog; Possesses thioredoxin activity (By similarity). Acts as a ligand for Drpr and is required for the phagocytosis of apoptotic cells. Binds to the extracellular region of Drpr and augments Drpr tyrosine phosphorylation ; Belongs to the protein disulfide isomerase family.
    
 
 0.881
crq
Croquemort (crq) encodes a member of the scavenger receptor class B sub-family. It is expressed in plasmatocyte/macrophages and promotes apoptotic cell clearance. In epidermal cells it plays a role in phagosome maturation in both dendrite pruning and injury.
   
  
 0.824
Crk
Adapter molecule Crk; Adapter protein which interacts with C-terminal portion of mbc, homolog of human DOCK180. May play a role in cellular processes throughout development; Belongs to the CRK family.
    
 
 0.823
CaBP1
Protein disulfide-isomerase A6 homolog; Calcium-binding protein 1 (CaBP1) encodes a protein that resides in the lumen of the endoplasmic reticulum. It seems to be relocated outside cells during apoptosis and involved in the phagocytosis of apoptotic cells.
    
 
 0.812
mbc
Myoblast city (mbc) encodes an unconventional bipartite GEF that, in combination with the product of Ced-12, activates the monomeric GTPase encoded by Rac1. It contributes to myoblast fusion, border cell migration and dorsal closure; Belongs to the DOCK family.
   
  
 0.773
Src42A
Tyrosine-protein kinase Src42A; Required directly or indirectly for the phosphorylation of drpr which is necessary for the interaction of drpr with shark and subsequent glial phagocytic activity. Together with drpr and shark, promotes the migration of macrophages to sites of wounding as part of a signaling cascade where Scr42a detects production of hydrogen peroxide at wound sites which triggers phosphorylation of drpr and subsequent recruitment and activation of shark. Essential for correct eye morphogenesis (ommatidial R7 neuron formation) which requires the Ras1/MAPK signal transduc [...]
