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

Cyp18a1Cytochrome P450-18a1 (Cyp18a1) encodes a P450 enzyme that inactivates the hormone 20 hydroxy ecdysone through addition of an OH group to the 26 carbon of the hormone molecule. It is expressed in many larval tissues. Cyp18a1 mutants result in prepupal lethality due to improper activation kinetics of the transcription factor encoded by ftz-f1. (538 aa)    
Predicted Functional Partners:
shd
Ecdysone 20-monooxygenase; Shade (shd) encodes 20-hydroxylase and is responsible for converting Ecdysone into 20-hydroxyecdysone, the active form of the steroid. It is required in all tissues that produce active Ecdysone and thus contributes to larval moulting, metamorphosis, growth, neuroblast diversity and egg chamber maturation; Belongs to the cytochrome P450 family.
  
0.954
nvd
Rieske-domain protein Neverland; Neverland (nvd) encodes an evolutionarily conserved oxygenase-like protein that is required for the biosynthesis pathway of ecdysone. It converts cholesterol to 7-dehydrocholesterol.
  
  
 0.808
ftz-f1
Nuclear hormone receptor FTZ-F1; Acts as a cofactor to fushi tarazu (ftz). Facilitates the binding of ftz to DNA. Binds the sequence element 5'-YCYYGGYCR-3' in the zebra element of ftz. Probably also functions as a receptor for a yet unknown ligand; Belongs to the nuclear hormone receptor family. NR5 subfamily.
   
 
 0.703
EcR
Ecdysone receptor (EcR) encodes a protein that interacts with the product of usp to form the nuclear ecdysone receptor heterodimer, which modulates, in conjunction with co-activators and co-repressors, the activities of hundreds of genes in a tissue- and stage-specific way. EcR is widely expressed in embryonic and larval tissues and in some adult tissues where its activities (modulated by the hormone ecdysone) trigger both molting and metamorphosis.
   
 
 0.609
CG6696
Metalloendopeptidase activity; zinc ion binding. It is involved in the biological process described with: proteolysis.
   
  
 0.608
Cyp309a1
Probable cytochrome P450 309a1; May be involved in the metabolism of insect hormones and in the breakdown of synthetic insecticides.
  
 
 0.581
sad
Shadow (sad) encodes a cytochrome P450 involved in ecdysteroid biosynthesis. It shows a mitochondrial localization and catalyzes the addition of a hydroxyl group to the 2 carbon of the cholesterol ring. sad mutants fail to undergo head involution, dorsal closure or to secrete cuticle.
  
 
0.579
Hr4
Hormone receptor 4; Coordinates growth and maturation by mediating endocrine responses to the attainment of critical weight during larval development. Plays a central role in the genetic cascades triggered by the steroid hormone ecdysone at the onset of metamorphosis, acting as both a repressor of the early ecdysone-induced regulatory genes and an inducer of the ftz-f1 midprepupal competence factor. Belongs to the nuclear hormone receptor family. NR1 subfamily.
    
 
 0.573
Cyp28a5
Probable cytochrome P450 28a5; May be involved in the metabolism of insect hormones and in the breakdown of synthetic insecticides.
  
 
 0.569
jhamt
Juvenile hormone acid O-methyltransferase; O-methyltransferase that transfers a methyl group from S- adenosyl-L-methionine (SAM) to the carboxyl group of juvenile hormone acids to produce active juvenile hormones in the corpora allata, the last step during juvenile hormone biosynthesis. Also able to methylate farnesoate to methyl farnesoate.
