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

Uba3Nedd8-activating enzyme E1 catalytic subunit; Catalytic subunit of the dimeric Uba3-APP-BP1 E1 enzyme. E1 activates Nedd8 by first adenylating its C-terminal glycine residue with ATP, thereafter linking this residue to the side chain of the catalytic cysteine, yielding a Nedd8-Uba3 thioester and free AMP. E1 finally transfers Nedd8 to the catalytic cysteine of UbcE2M. Required for Cul1 and Cul3 neddylation. Negatively regulates full-length ci stability and hedgehog signaling. (450 aa)    
Predicted Functional Partners:
APP-BP1
Nedd8-activating enzyme E1 regulatory subunit; Regulatory subunit of the dimeric Uba3-APP-BP1 E1 enzyme. E1 activates Nedd8 by first adenylating its C-terminal glycine residue with ATP, thereafter linking this residue to the side chain of the catalytic cysteine, yielding a Nedd8-Uba3 thioester and free AMP. E1 finally transfers Nedd8 to the catalytic cysteine of UbcE2M. Required for Cul1 and Cul3 neddylation. Appl and APP-BP1 interact antagonistically during development.

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.
   
 0.999
UbcE2M
Nedd8-conjugating enzyme UbcE2M; Accepts the ubiquitin-like protein Nedd8 from the Uba3-APP- BP1 E1 complex and catalyzes its covalent attachment to other proteins. Required for Cul1 and Cul3 neddylation. Negatively regulates full- length ci stability and hedgehog signaling.
   
 0.997
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 [...]

Den1
Deneddylase 1, isoform C; NEDD8-specific protease activity. It is involved in the biological process described with: positive regulation of apoptotic process; protein deneddylation.
   
 
 0.921
Cul3
Cullin 3, isoform F; Ubiquitin protein ligase binding; molecular adaptor activity; ubiquitin-protein transferase activity; protein binding; Belongs to the cullin family.
   
 0.916
SCCRO
DCN1-like protein; May contribute to neddylation of cullin components of SCF- type E3 ubiquitin ligase complexes. Neddylation of cullins play an essential role in the regulation of SCF-type complexes activity (By similarity).
   
 0.883
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 [...]

Uba1
Ubiquitin activating enzyme 1 (Uba1) encodes an E1 enzyme involved in protein ubiquitylation. It contributes to multiple processes including regulation of Ras-ERK signaling, autophagy, apoptosis and tissue growth; Belongs to the ubiquitin-activating E1 family.
   
0.870
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.
