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

ula-1NEDD8-activating enzyme E1 regulatory subunit; Regulatory subunit of the dimeric uba-3-ula-1 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-rfl-1 (uba-3) thioester and free AMP. E1 finally transfers NEDD8 to the catalytic cysteine of ubc-12. Required for rfl-1 (uba-3) nuclear localization during early embryonic development. Belongs to the ubiquitin-activating E1 family. ULA1 subfamily. (543 aa)    
Predicted Functional Partners:
rfl-1
NEDD8-activating enzyme E1 catalytic subunit; Catalytic subunit of the dimeric rfl-1 (uba-3)-ula-1 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-uba-3 thioester and free AMP. E1 finally transfers NEDD8 to the catalytic cysteine of ubc-12 (By similarity). Required for cytokinesis and mitotic spindle orientation during early embryogenesis.

ned-8
NEDD8; Ubiquitin-like protein which plays an important role in cell cycle control and embryogenesis. Covalent attachment to its substrates requires prior activation by the E1 complex uba-3-ula-1 and linkage to the E2 enzyme ubc-12. Attachment of ned-8 to cullins activates their associated E3 ubiquitin ligase activity, and thus promotes polyubiquitination and proteasomal degradation of cyclins and other regulatory proteins.
   
 
 0.990
ubc-12
NEDD8-conjugating enzyme ubc-12; Accepts the ubiquitin-like protein NEDD8 from the uba-3-ula-1 E1 complex and catalyzes its covalent attachment to other proteins. Plays a role in male tail tip morphogenesis.

csn-5
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 [...]

nmrk-1
Molybdopterin synthase catalytic subunit; Catalytic subunit of the molybdopterin synthase complex, a complex that catalyzes the conversion of precursor Z into molybdopterin. Acts by mediating the incorporation of 2 sulfur atoms from thiocarboxylated MOCS2A into precursor Z to generate a dithiolene group.
  
 0.837
cul-1
Cullin-1; Probable core component of multiple cullin-RING-based SCF (SKP1-CUL1-F-box) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. As a scaffold protein may contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme. Required for developmentally programmed transitions from the G1 phase of the cell cycle to the G0 phase or the apoptotic pathway.

rpl-1
60S ribosomal protein L10a; Belongs to the universal ribosomal protein uL1 family.

smo-1
Small ubiquitin-related modifier; Ubiquitin-like protein which can be covalently attached to target lysines as a monomer. Does not seem to be involved in protein degradation and may function as an antagonist of ubiquitin in the degradation process. Plays a role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduction. Covalent attachment to its substrates requires prior activation by the E1 complex aos-1-uba-2 and linkage to the E2 enzyme ubc-9, and can be promoted by an E3 ligase such as gei-17. Required for embryonic dev [...]

rpn-11
26S proteasome non-ATPase regulatory subunit 14; Metalloprotease component of the 26S proteasome that specifically cleaves 'Lys-63'-linked polyubiquitin chains. The 26S proteasome is involved in the ATP-dependent degradation of ubiquitinated proteins. The function of the 'Lys-63'-specific deubiquitination of the proteasome is unclear (By similarity).
