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

ulp-1Sentrin-specific protease; Protease that deconjugates smo-1 from targeted proteins and may catalyze the processing of smo-1 to its mature form. (697 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 [...]

ulp-4
Ubiquitin-like protease 4; Protease required for deconjugation of smo-1 conjugates from target proteins which is necessary for cell cycle progression. Required for respiration and the maintenance of normal mitochondrial homeostasis.
    
 
 0.951
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.
   
 
 0.947
ubc-9
SUMO-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.
   
 
 0.943
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).
   
 
 0.942
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.
   
 
 0.926
ulp-5
ULP_PROTEASE domain-containing protein.
   
 0.925
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).
   
 
 0.909
imb-3
Importin N-terminal domain-containing protein.
   
 
 0.891
K10G6.4
Uncharacterized protein.
   
 
 0.888
