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

poeProtein purity of essence; Has a role in growth of the perineurial glial layer of the larval peripheral nerve. May have a role in male fertility and eye development or function. Involved in the negative regulation of the Ras/MAPK signaling pathway in the wing by acting with the E2 enzyme Unc6 and the putative E3 ligases Kcmf1 and Ufd4 to mediate the ubiquitination and proteasomal degradation of rl/MAPK. (5322 aa)    
Predicted Functional Partners:
Ubr1
E3 ubiquitin-protein ligase UBR1; E3 ubiquitin-protein ligase which is a component of the N-end rule pathway. Recognizes and binds to proteins bearing specific N- terminal residues that are destabilizing according to the N-end rule, leading to their ubiquitination and subsequent degradation. Belongs to the UBR1 family.
   
  
 0.824
Ufd4
E3 ubiquitin-protein ligase Ufd4; E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates (By similarity). Involved in the negative regulation of the Ras/MAPK signaling pathway in the wing by acting with the E2 enzyme Unc6 and the putative E3 ligases poe and Kcmf1 to mediate the ubiquitination and proteasomal degradation of rl/MAPK.
   
  
 0.822
Kcmf1
E3 ubiquitin-protein ligase Kcmf1; Has intrinsic E3 ubiquitin ligase activity and promotes ubiquitination. Involved in the negative regulation of the Ras/MAPK signaling pathway in the wing by acting with the E2 enzyme Unc6 and the putative E3 ligases poe and Ufd4 to mediate the ubiquitination and proteasomal degradation of rl/MAPK.

CG15286
AT31519p; Ubiquitin protein ligase activity; zinc ion binding. It is involved in the biological process described with: synaptic signaling.
    
 
 0.751
HUWE1
Uncharacterized protein, isoform H; Ubiquitin-protein transferase activity; ubiquitin protein ligase activity. It is involved in the biological process described with: protein ubiquitination; ubiquitin-dependent protein catabolic process; protein polyubiquitination; dsRNA transport.
   
  
 0.736
Ubi-p5E
Ubiquitin-5E, isoform A; Protein tag; ubiquitin protein ligase binding. It is involved in the biological process described with: ubiquitin-dependent protein catabolic process; protein ubiquitination; modification-dependent protein catabolic process; cellular protein modification process.
   
 0.727
Hk
Hyperkinetic, isoform M; Hyperkinetic (Hk) encodes a beta-subunit of Sh K[+] channels and modulates its channel function. It is important in regulating action potentials in neurons and muscles, and transmitter release.
     
 0.706
Dhc64C
Dynein heavy chain 64C (Dhc64C) encodes the heavy chain subunit of the cytoplasmic dynein motor complex. The product of Dhc64C forms a dimer, which binds and hydrolyzes ATP providing the power for movement of dynein. It has an essential function in oocyte polarity, mitotic cell division, embryonic development, and neuronal transport and neurogenesis.
   
  
 0.677
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.
   
 
 0.664
Ltn1
E3 ubiquitin-protein ligase listerin; E3 ubiquitin-protein ligase component of the ribosome quality control complex (RQC), a ribosome-associated complex that mediates ubiquitination and extraction of incompletely synthesized nascent chains for proteasomal degradation. Ubiquitination leads to TER94/VCP recruitment for extraction and degradation of the incomplete translation product (By similarity). Belongs to the LTN1 family.
