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

ubc-9SUMO-conjugating enzyme UBC9; Accepts the ubiquitin-like protein smo-1 from the aos-1-uba-2 E1 complex and catalyzes its covalent attachment to other proteins with the help of an E3 ligase such as gei-17. Required to sumoylate the ETS transcription factor lin-1 and the Polycomb protein sop-2. Required for embryonic development, fertility, vulval morphogenesis and inhibition of vulval cell fates. Belongs to the ubiquitin-conjugating enzyme family. (166 aa)    
Predicted Functional Partners:
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 [...]

uba-2
SUMO-activating enzyme subunit uba-2; The dimeric enzyme acts as an E1 ligase for smo-1. It mediates ATP-dependent activation of smo-1 and formation of a thioester with a conserved cysteine residue on uba-2 (Probable).
  
 0.997
gei-17
E3 SUMO-protein ligase gei-17; Functions as an E3-type smo-1 ligase. Mediates smo-1 conjugation to air-2 in vitro and is required for proper chromosome alignment. In the early embryo, specifically suppresses checkpoint activation in response to DNA damage, maybe by promoting mus-101 sumoylation. In embryos, plays a role in determining telomere localization in the nucleus.
   
 0.993
aos-1
SUMO-activating enzyme subunit aos-1; The dimeric enzyme acts as an E1 ligase for smo-1. It mediates ATP-dependent activation of smo-1 and formation of a thioester with a conserved cysteine residue on uba-2 (Probable).
  
 0.989
ran-2
Ran GTPase-activating protein 2; GTPase system comprising ran-1, ran-2 and ran-3 is essential in nucleocytoplasmic trafficking. Ran-2 is a GTPase activator for the nuclear RAS-related regulatory protein Ran, converting it to the putatively inactive GDP-bound state. Required for correct chromosome alignment and segregation on the metaphase plate.
   
 0.978
npp-9
Nuclear Pore complex Protein.
   
 0.950
ulp-1
Sentrin-specific protease; Protease that deconjugates smo-1 from targeted proteins and may catalyze the processing of smo-1 to its mature form.
   
 
 0.943
pcn-1
Proliferating cell nuclear antigen; This protein is an auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase's processibility during elongation of the leading strand; Belongs to the PCNA family.
   
 0.919
uev-2
UBIQUITIN_CONJUGAT_2 domain-containing protein.
  
  
 
0.908
asns-2
Glutamine amidotransferase type-2 domain-containing protein.
