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

Spn42DdSerine protease inhibitor 42Dd; Serine protease inhibitor with activity toward trypsin. Involved in innate immunity to fungal infection by negatively regulating the Toll signaling pathway and suppressing the expression of the antifungal peptide drosomycin. Acts upstream of SPE and grass, and downstream of the fungal cell wall pattern recognition receptor GNBP3. May function specifically in the GNBP3-dependent beta-1,3-glucan branch of the Toll pathway. (372 aa)    
Predicted Functional Partners:
nec
GH10112p; Necrotic (nec) encodes a hemolymphatic Serpin that negatively regulates a serine protease involved in the immune activation of the Toll pathway. It is thought to function at the level or upstream of the serine protease encoded by psh.

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 [...]

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.

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.
