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

serpSerpentine, isoform B; Serpentine (serp) encodes a putative chitin deacetylase. It is expressed by the epidermal and tracheal cells and is secreted into the apical extracellular space. Its activity maintains the strength of cuticles and restricts tracheal tube length. (541 aa)    
Predicted Functional Partners:
obst-A
Obstructor-A, isoform A; obstructor-A (obst-A) encodes a protein that forms a core complex with chitin and the chitin modifying proteins encoded by serp and knk. This complex is required for assembly, maturation and preservation of the chitinous cuticles at the end of embryogenesis and probably throughout larval development.
  
 
 0.984
Gasp
Gasp, isoform A; Gasp (Gasp) encodes a protein involved in cuticle biosynthesis during embryonic tracheal system development.
   
  
 0.975
verm
Vermiform, isoform I; Vermiform (verm) encodes a chitin deacetylase-like protein that is secreted by tracheal cells and accumulates in the embryonic tracheal lumen. Its functions include cuticle development and tracheal tube size control.
  
 
0.926
Cda4
Chitin deacetylase-like 4; Chitin binding. It is involved in the biological process described with: chitin metabolic process; carbohydrate metabolic process.
  
  
0.860
uif
Uninflatable, isoform C; Uninflatable (uif) encodes a single pass transmembrane protein that localizes to the apical plasma membrane in epithelial cells. It is required for embryonic tracheal maturation and tracheal growth in the larva.
  
  
 0.858
knk
Knickkopf (knk) encodes a GPI-anchorded protein, needed for chitin organisation in the cuticle and the tracheal system (tracheal cuticle, tube diameter regulation & gas filling).
   
  
 0.857
kkv
Krotzkopf verkehrt (kkv) encodes a membrane-inserted glycosyltransferase family 2 chitin synthase that uses GlcNAc to produce the polysaccharide chitin, which is extruded to the differentiating cuticle and tracheal system (tracheal cuticle, tube diameter regulation and gas filling).
   
  
 0.775
slf
C-type lectin 27kD, isoform A; Schlaff (slf) encodes a chitin binding protein involved in wing formation and the substrate for the product of Tg.
   
  
 0.758
CG4115
LD12305p; Carbohydrate binding.
   
  
 0.726
Vajk2
RH04334p; Chitin binding; structural constituent of chitin-based cuticle. It is involved in the biological process described with: chitin-based cuticle development.
   
  
 0.713
