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

MP1Melanization protease 1; Serine protease which plays an essential role in the melanization immune response by acting downstream of sp7 to activate prophenoloxidase (PPO1). May function in diverse Hayan-dependent PPO1-activating cascades that are negatively controlled by different serpin proteins; Spn27A in the hemolymph and Spn77BA in the trachea. Regulation of melanization and PPO1 activation appears to be largely independent of the Toll signaling pathway. Belongs to the peptidase S1 family. CLIP subfamily. (400 aa)    
Predicted Functional Partners:
Sp7
Serine protease 7; Serine protease which, by cleaving and activating prophenoloxidase (PPO1) after immune challenge, plays an essential role in the melanization immune response to septic wounding. May function in diverse Hayan-dependent PPO1- activating cascades that are negatively controlled by different serpin proteins; Spn27A in the hemolymph and Spn77BA in the trachea. Important for the innate immune response to fungi. Regulation of melanization and PPO1 activation appears to be largely independent of the Toll signaling pathway.

Spn27A
Serine protease inhibitor 27A; Serine protease inhibitor that functions in embryonic dorsoventral patterning and the melanization immune response. Regulates dorsoventral axis formation during early development by inhibiting the serine protease easter, and is therefore important for restricting activity of the Toll signaling pathway to the ventral part of the embryo. Also plays an essential role in the melanization immune response to both physical wounding and septic infection using certain bacteria and fungi. Negatively regulates the Hayan- dependent prophenoloxidase 1 (PPO1)-activatin [...]

Spn77Ba
Serine protease inhibitor 77Ba; Serine protease inhibitor which plays an essential role in regulating the tracheal melanization immune response to bacterial and fungal infection. Acts by negatively regulating a protease cascade involving Mp1 and Sp7, that functions in the activation of the Hayan-phenoloxidase (PPO1) cascade ; Belongs to the serpin family.
   
 
 0.541
Spn28Dc
Serine protease inhibitor 28Dc; Serine protease inhibitor which is required for pupal viability and plays an essential role in regulating the melanization reaction. Inhibits spontaneous melanization and appears to be involved in the melanization immune response to physical wounding in larvae and adults. Acts by negatively regulating the Hayan-phenoloxidase (PPO1) cascade in the hemolymph and possibly the trachea. May function by controlling the initial release of the activated form of PPO1, phenoloxidase (PO) and thus maintains PO availability for processes such as wound response and p [...]

IM33
Immune induced molecule 33 (IM33) encodes a protein that belongs to a class of small secreted peptides released in the hemolymph upon systemic microbial infection.
   
 
 0.469
GNBP1
Gram-negative bacteria-binding protein 1; Plays a key role in innate immunity by acting as a pattern recognition receptor for beta-1,3-glucan from fungi and lipopolysaccharide from Gram-negative bacteria. Upon recognition of invading micro-organism-derived products, acts upstream of protease spz processing enzyme SPE to activate the Toll pathway and to induce the expression of antimicrobial peptides drosomycin, cecropin and attacin. Belongs to the insect beta-1,3-glucan binding protein family.
   
 
 0.441
Spn31A
Serpin 31A; Serine-type endopeptidase inhibitor activity. It is involved in the biological process described with: negative regulation of endopeptidase activity; Belongs to the serpin family.
    
 
 0.433
CG11438
RH32172p; Phosphatidate phosphatase activity; phosphatase activity; lipid phosphatase activity. It is involved in the biological process described with: phospholipid dephosphorylation; phospholipid metabolic process; signal transduction.

CG16756
GEO08277p1; Lysozyme activity. It is involved in the biological process described with: defense response to Gram-negative bacterium; Belongs to the glycosyl hydrolase 22 family.
