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

PGRP-LFPeptidoglycan recognition protein LF (PGRP-LF) encodes a transmembrane receptor that prevents the spontaneous activation of the immune deficiency pathway receptor encoded by PGRP-LC. (369 aa)    
Predicted Functional Partners:
PGRP-LC
Peptidoglycan-recognition protein LC; Major activator of the imd/Relish pathway and is likely to encode a pattern recognition molecule for the humoral immune response. Required for Relish processing and nuclear translocation following proteolytic cleavage. Involved in the response to lipopolysaccharide (LPS) and peptidoglycan of Gram-negative bacteria. The different isoforms probably display different recognition capabilities to various microbial patterns. [Isoform x]: Mediates the response to LPS, peptidoglycan and Gram-negative bacteria; Belongs to the N-acetylmuramoyl-L-alanine amid [...]

Rel
Nuclear factor NF-kappa-B p110 subunit; Plays a key role in the humoral immune response. Rel-p68 subunit translocates to the nucleus where it binds to the promoter of the Cecropin A1 gene and probably other antimicrobial peptide genes. I-kappa-B kinase complex (IKKbeta and key) and PGRP-LC are essential signaling components in transmitting the lipopolysaccharide (LPS) signal leading to cact degradation for NF-kappa-B (rel) activation. Part of a Toll-related receptor pathway that functions in the apoptosis of unfit cells during cell competition. May be part of a NF-kappa-B and Tollo sig [...]
   
 0.956
imd
Protein immune deficiency; Essential for the imd/NF-kappa-B (Imd) humoral and epithelial immune response to Gram-negative bacteria. Functions as an adapter protein that transduces immunity signals from the activation of pathogen recognition receptors (PRRs) by bacterial infection to the Imd signaling pathway. Binding of diaminopimelic acid-type (DAP-type) bacterial peptidoglycans (PGN) causes multimerization or clustering of PGRP receptors which activate the Imd cascade probably by recruiting imd, Fadd and Dredd to the receptor complex. Once in proximity, Dredd cleaves imd in a Fadd-de [...]
    
 
 0.833
pirk
Poor Imd response upon knock-in (pirk) encodes a negative regulator of the immune deficiency (Imd) pathway, acting at the level of the product of PGRP-LC. Being regulated by the Imd pathway itself, it establishes a negative feedback loop adjusting Imd pathway activity to the severity of infection.
   
  
 0.763
DptB
Diptericin B (DptB) encodes an immune inducible antibacterial peptide with activity against Gram-negative bacteria. It is expressed in the fat body during the systemic immune response and in various epithelia. Its expression is regulated at the transcriptional level by the immune deficiency pathway.
   
  
 0.612
GNBP3
Gram-negative bacteria binding protein 3 (GNBP3) encodes a hemolymphatic protein involved in the sensing of glucan (a fungal cell wall component) upstream of the Toll pathway.
      
 0.603
Sc2
Sc2; Oxidoreductase activity; oxidoreductase activity, acting on the CH-CH group of donors. It is involved in the biological process described with: very long-chain fatty acid biosynthetic process.
      
 0.601
DptA
Diptericin A (DptA) encodes an immune inducible antibacterial peptide with activity against Gram-negative bacteria. It is expressed in the fat body during the systemic immune response and in various epithelia. Its expression is regulated at the transcriptional level by the immune deficiency pathway; Belongs to the attacin/sarcotoxin-2 family.
   
  
 0.546
AttD
Attacin-D (AttD) encodes is an immune inducible peptide that shows homology to antibacterial peptides having activity against Gram-negative bacteria.
   
  
 0.545
TM9SF2
Transmembrane 9 superfamily member; It is involved in the biological process described with: protein localization to membrane; negative regulation of peptidoglycan recognition protein signaling pathway; Belongs to the nonaspanin (TM9SF) (TC 9.A.2) family.
