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

ntcProtein nutcracker; Functions together with PI31 to control non-apoptotic caspase activation during sperm individualization. Positively regulates PI31 stability. (314 aa)    
Predicted Functional Partners:
PI31
Proteasome inhibitor PI31 subunit; Plays an important role in the control of proteasome function. Inhibits the hydrolysis of protein and peptide substrates by the 20S proteasome. Enhances 26S proteasome function by promoting its assembly through the interaction with the assembly chaperones PSMD9 and PMSD5. Functions together with ntc to control non-apoptotic caspase activation during sperm individualization. In testis, is required for proper protein degradation and germline cell cycle progression.

Cul1
Cullin homolog 1; Core component of multiple SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination of proteins involved in cell cycle progression, signal transduction and transcription. In the SCF complex, serves as a rigid scaffold that organizes the SKP1-F-box protein and RBX1 subunits. May contribute to catalysis through positioning of the substrate and the ubiquitin- conjugating enzyme. During early metamorphosis, part of the SCF-slmb complex that negatively regulates the InR/PI3K/TOR pathway to activate the pruning of unnecessary larv [...]

Cul6
Cullin 6; Ubiquitin-protein transferase activity; ubiquitin protein ligase binding; Belongs to the cullin family.
   
 
 0.968
SkpA
SKP1-related A (SkpA) encodes a subunit of Skp, Cullin, F-box (SCF)-containing ubiquitin ligase complexes. It regulates centrosome duplication, chromatin condensation, cell cycle progression, cell polarity, dendrite pruning and endoreduplication.
    
 
 0.946
Cul3
Cullin 3, isoform F; Ubiquitin protein ligase binding; molecular adaptor activity; ubiquitin-protein transferase activity; protein binding; Belongs to the cullin family.
   
 
 0.781
Roc1b
RING-box protein 1B; Component of the SCF (SKP1-CUL1-F-box protein) E3 ubiquitin ligase complex, which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Through the RING-type zinc finger, seems to recruit the E2 ubiquitination enzyme to the complex and brings it into close proximity to the substrate (By similarity). Belongs to the RING-box family.
    
 
 0.777
Skp2
S-phase kinase-associated protein 2 (Skp2) encodes the substrate recognizing component of the SCF-Skp2 ubiquitin ligase. It functions with the product of Cks85A to target the product of dap for destruction. It is required for larval growth and to maintain diploidy in imaginal tissues.
    
 
 0.712
aux
Auxilin, isoform A; Auxilin (aux) encodes a co-factor for the ATPase Hsc70 that regulates Clathrin dynamics. It regulates Notch signaling, eye morphogenesis, sperm individualization and neuron death.
   
 
 0.703
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.

mRpL2
Mitochondrial ribosomal protein L2; RNA binding; structural constituent of ribosome. It is involved in the biological process described with: mitochondrial translation.
