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

rprCell death protein rpr; Reaper (rpr) encodes Reaper, Hid, Grim (RHG) protein. It contributes to the caspase dependent apoptosis by inhibiting the anti-apoptotic protein encoded by Diap1. (65 aa)    
Predicted Functional Partners:
Diap1
Death-associated inhibitor of apoptosis 1; Anti-apoptotic protein which functions as a caspase regulator, using its E3 ubiquitin-protein ligase activity to smother caspase activity. Binds, ubiquitinates and inactivates initiator caspase Dronc, and effector caspases Drice and Dcp-1. Acts as a Nedd8- E3 ubiquitin-protein ligase for Drice. Suppresses apoptosis by targeting the apoptosome for ubiquitination and inactivation. Plays an important role in cell motility. Overexpression suppresses rpr and hid- dependent cell death in the eye. Interaction of Diap1 with Dronc is required to suppre [...]

Dronc
Caspase Nc subunit 1; Involved in the activation cascade of caspases responsible for apoptosis execution. Effector of steroid-mediated apoptosis during insect metamorphosis. Overexpression promotes programmed cell death. Interaction with Diap1 is required to suppress Dronc-mediated cell death; via Diap1-mediated ubiquitination of Dronc. Rate-limiting caspase in rpr and hid death pathway.
   
 
 0.990
Bruce
BIR repeat containing ubiquitin-conjugating enzyme (Bruce) encodes a BIR domain containing anti-apoptotic protein of the inhibitor of apoptosis (IAP) protein family. It blocks apoptosis in part by binding to and ubiquitylating pro-apoptotic proteins such as the product of rpr. Bruce mutants are viable, but are vulnerable to apoptosis and show defects in spermatid differentiation.
    
 0.985
grim
Cell death protein Grim; Grim (grim) encodes a member of the inhibitor of apoptotic protein antagonists. In response to death signals, it induces apoptosis of cells in the central nervous system. It is important particularly for the apoptosis of specific juvenile neurons during metamorphosis.
    
 
 0.984
Drice
Caspase subunit p12; Death related ICE-like caspase (Drice) encodes a major effector apoptotic caspase. It is essential for both developmental and damaged induced cell death, as well as several non-apoptotic vital cellular processes. It is activated by the product of Dark and the initiator caspase encoded by Dronc and is inhibited by the inhibitor of apoptosis encoded by Diap1; Belongs to the peptidase C14A family.
   
 
 0.980
Dark
Death-associated APAF1-related killer, isoform B; Death-associated APAF1-related killer (Dark) encodes an essential component of the apoptosome. The products of Dark and Dronc form a pivotal holoenzyme required for apoptotic cell death with the products of Dark acting as an adaptor of the multimeric complex.
    
 
 0.931
Diap2
Death-associated inhibitor of apoptosis 2; Required for activation of NF-kappaB transcription factors in the immune deficiency (Imd) signaling cascade which is essential for innate immune responses upon infection by Gram-negative bacteria. Promotes cytoplasmic cleavage of Rel and its translocation to the nucleus where it drives expression of antimicrobial peptides. Binds, polyubiquitinates and activates Dredd which is required for Rel- mediated induction of antimicrobial peptides. Anti- apoptotic protein which binds, ubiquitinates and inactivates the effector caspase Drice. Suppresses [...]

Marf
Transmembrane GTPase Marf; Mitochondrial assembly regulatory factor (Marf) encodes a dynamin-family GTPase that mediates outer mitochondrial membrane tethering and fusion. Marf loss causes mitochondrial fragmentation and endoplasmic reticular stress that evoke skeletal muscle, retinal and heart tube dysfunction; Belongs to the TRAFAC class dynamin-like GTPase superfamily. Dynamin/Fzo/YdjA family. Mitofusin subfamily.
     
 0.908
fzo
Transmembrane GTPase fzo; Essential transmembrane GTPase, which mediates mitochondrial fusion during spermatogenesis. In early spermatocytes, fusion of mitochondria give rise to two organelles named Nebenkern and constitutes an important step in mitochondria morphology, which is balanced between fusion and fission. Essential for fertility.
     
  0.900
egr
Protein eiger, membrane form; Cytokine which acts as a ligand for wgn. Also acts as a ligand for grnd. Induces apoptosis by triggering JNK signaling. Required for JNK-dependent non-autonomous apoptosis through release from apoptotic cells and activation of apoptosis in neighboring cells. Required for JNK-independent damage-induced apoptosis in the embryonic central nervous system through regulation of the pro-apoptotic gene hid. Involved in the innate immune response to extracellular pathogens. Plays a role in the melanization immune response through its involvement in the rupture of c [...]
