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-LBPeptidoglycan recognition protein LB (PGRP-LB) encodes a secreted protein with an amidase activity that scavenges DAP-type peptidoglycan, a cell wall component found on Gram-negative bacteria and certain Gram positive bacteria. It negatively regulates the immune deficiency pathway; Belongs to the N-acetylmuramoyl-L-alanine amidase 2 family. (255 aa)    
Predicted Functional Partners:
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 [...]

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 [...]

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.

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.
   
  
 0.828
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.
   
  
 0.802
PGRP-LD
Peptidoglycan-recognition protein LD; Peptidoglycan-recognition protein probably involved in innate immunity by binding to peptidoglycans (PGN) of bacteria and activating the immune response; Belongs to the N-acetylmuramoyl-L-alanine amidase 2 family.
      
 0.794
CecB
Cecropin-B; Cecropin B (CecB) encodes an helicoidal antibacterial peptide with activity against Gram-negative bacteria. It is mostly expressed at the pupal stage; Belongs to the cecropin family.
   
  
 0.740
AttD
Attacin-D (AttD) encodes is an immune inducible peptide that shows homology to antibacterial peptides having activity against Gram-negative bacteria.
   
  
 0.732
CecC
Cecropin-C; Cecropin C (CecC) encodes an antibacterial peptide with activity against Gram-negative bacteria. It is strongly expressed at the pupal stage.
   
  
 0.713
Def
Defensin (Def) encodes an antibacterial peptide with activity against Gram-positive bacteria. It is induced in the fat body during the systemic immune response and is expressed in various epithelia. The expression of Def is regulated at the transcriptional level by both the immune deficiency and Toll pathways; Belongs to the invertebrate defensin family. Type 1 subfamily.
