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

Cand1Cullin-associated NEDD8-dissociated protein 1; Key assembly factor of SCF (SKP1-CUL1-F-box protein) E3 ubiquitin ligase complexes that promotes the exchange of the substrate- recognition F-box subunit in SCF complexes, thereby playing a key role in the cellular repertoire of SCF complexes. Acts as a F-box protein exchange factor. Probably plays a similar role in other cullin-RING E3 ubiquitin ligase complexes (Probable); Belongs to the CAND family. (1248 aa)    
Predicted Functional Partners:
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 [...]

Cul4
Cullin 4 (Cul4) encodes the molecular scaffold for the CRL4 E3 ubiquitin ligase complex, which catalyzes the ubiquitylation and subsequent destruction of proteins that function in cell growth and proliferation as well as transcription, replication and repair of the genome; Belongs to the cullin family.
   
 0.982
Cul3
Cullin 3, isoform F; Ubiquitin protein ligase binding; molecular adaptor activity; ubiquitin-protein transferase activity; protein binding; Belongs to the cullin family.
   
 0.977
Cul2
Cullin 2 (Cul2) encodes a protein that plays important roles during oogenesis. Reduction of the product of Cul2 in somatic cells produces tumorous germaria with excess germline stem cell-like cells due to the elevation of Dpp signaling in the niche; Belongs to the cullin family.

Roc1a
RING-box protein 1A; 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. 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. Required for the specific SCF-dependent proteolysis of CI, but not that of ARM, suggesting that it also participates in the selection of substrates inside the SCF complex. During early metamorphosis, part of [...]

Cul6
Cullin 6; Ubiquitin-protein transferase activity; ubiquitin protein ligase binding; Belongs to the cullin family.
   
 
 0.947
Nedd8
NEDD8; Ubiquitin-like protein which plays an important role in cell cycle control, embryogenesis and neurogenesis. Covalent attachment to its substrates requires prior activation by the E1 complex Uba3-Ula1 and linkage to the E2 enzyme UbcE2M. Attachment of Nedd8 to cullins activates their associated E3 ubiquitin ligase activity, and thus promotes polyubiquitination and proteasomal degradation of cyclins and other regulatory proteins.
    
 
 0.941
Cul5
FI20194p1; Cullin 5 (Cul5) is expressed in both neuronal and non-neuronal cells (such as in fusion sites of embryonic trachea). Reduction of the product of Cul5 in neuronal cells results in an increase in number of synaptic boutons in the larval neuromuscular junction; Belongs to the cullin family.
   
 0.933
CSN5
COP9 signalosome complex subunit 5; Probable protease subunit of the COP9 signalosome complex (CSN), a complex involved in various cellular and developmental processes. The CSN complex is an essential regulator of the ubiquitin (Ubl) conjugation pathway by mediating the deneddylation of the cullin subunits of the SCF-type E3 ligase complexes, leading to decrease the Ubl ligase activity of SCF. In the complex, it probably acts as the catalytic center that mediates the cleavage of Nedd8 from cullins. It however has no metalloprotease activity by itself and requires the other subunits of [...]

EloC
Elongin C (EloC) encodes an essential protein for development that participates in the control of wing cell identity. EloB, EloC and EloA encode for subunits of the Elongin complex, which interacts in vivo with the chromatin factor encoded by corto.
