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

spzProtein spaetzle C-106; Spatzle (spz) encodes a secreted protein which, after cleavage by an extracellular serine protease (encoded by ea or SPE), can induce the dimerization of the product of Tl, and the subsequent activation of the Toll pathway. It contributes to function of the Toll signaling cascade, which plays a key role in various developmental and immune processes, notably embryonic dorso-ventral patterning and regulation of antimicrobial peptides. (326 aa)    
Predicted Functional Partners:
Tl
Protein toll; Receptor for the cleaved activated form of spz, spaetzle C- 106. Binding to spaetzle C-106 activates the Toll signaling pathway and induces expression of the antifungal peptide drosomycin. Component of the extracellular signaling pathway that establishes dorsal-ventral polarity in the embryo. Promotes heterophilic cellular adhesion. Involved in synaptic targeting of motoneurons RP5 and V to muscle 12 (M12); functions as a repulsive cue inhibiting motoneuron synapse formation on muscle 13 (M13) to guide RP5 and V to the neighboring M12, where its expression is repressed by [...]
   
 0.999
SPE
Spaetzle-processing enzyme heavy chain; Endopeptidase which plays a key role in innate immunity by cleaving Tl ligand spz and thereby activating the Toll pathway in response to fungal and Gram-positive bacterial infections. Acts downstream of pathogen recognition receptors PGRP-SA and GNBP1 and protease grass in response to Gram-positive bacterial infection. Acts downstream of protease psh in response to fungal infection. Belongs to the peptidase S1 family. CLIP subfamily.
    
 0.983
ea
Serine protease easter; Component of the extracellular signaling pathway that establishes the dorsal-ventral pathway of the embryo. Three proteases; ndl, gd and snk process easter to create active easter. Active easter defines cell identities along the dorsal-ventral continuum by activating the spz ligand for the Tl receptor in the ventral region of the embryo.
   
 0.945
cact
NF-kappa-B inhibitor cactus; Involved in the formation of the dorsoventral pattern. It inhibits nuclear translocation of the dorsal morphogen in the dorsal region of the embryo. Acts as a negative regulator of the NF-kappa-B (rel) signaling pathway. Cact is degraded by IKKbeta, this is essential for NF-kappa-B (rel) activation.
   
 0.928
Myd88
Myd88 (Myd88) encodes an adaptor protein involved in in the Toll pathway functioning downstream of the product of Tl and upstream of the product of tub. Toll pathway is a signaling cascade that plays a key role in various developmental and immune processes, notably embryonic dorsoventral patterning and regulation of antimicrobial peptides.
   
 0.926
Dif
Dorsal-related immunity factor Dif; Mediates an immune response in larvae. DIF binds to the kappa-B consensus sequence 5'-GGRNNYYCC-3', located in the enhancer region of the immunity gene CECA1. Involved in the melanization immune response to bacterial challenge, possibly by acting in a Toll signaling pathway that downregulates Spn27A in response to infection. Part of a signaling pathway involving NF-kappa-B (rel) and Toll-related receptors, that functions in the apoptosis of unfit cells during cell competition. May be part of a NF-kappa-B and Tollo signaling cascade that regulates dev [...]
     
 0.913
Toll-7
Toll-like receptor 7; Toll-related receptor which binds to the neurotrophins NT1 and spz5. Essential for antiviral autophagy, it detects and binds to the vesicular stomatitis virus (vsv) following infection. This role is likely to be independent of the canonical Toll, immune deficiency, and JAK-STAT signaling pathways. Functions in olfactory circuit assembly by promoting synaptic partner matching between olfactory receptor neurons (ORN) axons and projection neurons (PN) dendrites partners in the antennal lobe. Function in the Va1d ORNs is necessary and sufficient for correct targeting [...]
    
 
 0.876
psh
Serine protease persephone; Serine protease that plays a key role in innate immunity in response to Gram-positive bacterial and fungal proteases. Acts as a component of the Toll pathway upstream of protease spz processing enzyme SPE and Tl ligand spz. Nec regulates the cascade by inhibiting psh ; Belongs to the peptidase S1 family. CLIP subfamily.
    
 
 0.847
modSP
Modular serine protease non-catalytic chain; Serine protease that plays a key role in innate immunity by activating the Toll pathway in response to infection with Gram-positive bacteria and fungi. During Gram- positive infection, acts downstream of PGRP-SA and upstream of Grass and Spz, and therefore appears to function in a pathway that links detection of Gram-positive lysine-type peptidoglycans to Toll activation. Functions in a separate pathway to the psh-mediated activation of the Toll pathway. Belongs to the peptidase S1 family.
    
 
 0.844
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 [...]
