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

rib-1Exostosin-1 homolog; Required for the biosynthesis of heparan sulfate by positively regulating N-acetylglucosamine transferase II (GlcNAcT-II) and glucuronyl transferase II (GlcAT-II) activities of glycosyltransferase rib-2. Probably not directly involved in chondroitin sulfate biosynthesis but negatively regulates chondroitin sulfate levels. Maternally required for normal ventral epidermal enclosure and for embryo elongation during the early stages of embryonic development. In addition, involved in the elongation of the pharyngeal isthmus and in the organization of the actin cytoskele [...] (382 aa)    
Predicted Functional Partners:
hst-1
Bifunctional heparan sulfate N-deacetylase/N-sulfotransferase 1; Essential bifunctional enzyme that catalyzes both the N- deacetylation and the N-sulfation of glucosamine (GlcNAc) of the glycosaminoglycan in heparan sulfate. Modifies the GlcNAc-GlcA disaccharide repeating sugar backbone to make N-sulfated heparosan, a prerequisite substrate for later modifications in heparin biosynthesis (Probable).

madd-3
Probable dual specificity protein kinase madd-3; [Isoform a]: Probable dual specificity kinase acting on both serine/threonine and tyrosine-containing substrates. Negatively regulates p38 MAPK signaling to allow for the plasma membrane of body wall muscle cells to form projections, also called muscle arms, that extend and connect the body wall muscles to target motor neurons. Negative regulation of p38 MAPK signaling may in turn modulate the trafficking of the muscle specific receptor eva-1 to the lysosome, to ensure proper display of the eva-1 receptor on the plasma membrane of muscle [...]

hst-6
Heparan-sulfate 6-O-sulfotransferase; 6-O-sulfation enzyme which catalyzes the transfer of sulfate from 3'-phosphoadenosine 5'-phosphosulfate (PAPS) to position 6 of the N-sulfoglucosamine residue (GlcNS) of heparan sulfate.
      
 0.845
hse-5
D-glucuronyl C5-epimerase; Converts D-glucuronic acid residues adjacent to N-sulfate sugar residues to L-iduronic acids (By similarity). Plays a role in the early migration of AQR and PQR neurons, which descend from the Q neuroblasts ; Belongs to the D-glucuronyl C5-epimerase family.
   
  
 0.840
hst-2
Heparan sulfate 2-O-sulfotransferase hst-2; Catalyzes the transfer of sulfate to the C2-position of selected hexuronic acid residues within the maturing heparan sulfate (HS). Involved in cell adhesion and guidance by specifically modifying proteoglycans in the extracellular matrix and on the cell surface that are essential for axon migrations.

hst-3.1
Sulfotransfer_1 domain-containing protein.
      
 0.758
hst-3.2
Sulfotransfer_1 domain-containing protein.
      
 0.749
sqv-8
Galactosylgalactosylxylosylprotein 3-beta-glucuronosyltransferase sqv-8; Glycosyltransferase required for the biosynthesis of the tetrasaccharide (GlcA-Gal-Gal-Xyl-)Ser core linker of heparan sulfate and chondroitin sulfate. May be involved in the biosynthesis of the HNK-1 carbohydrate epitope on glycoproteins. Required for embryonic development. Involved in the elongation of the pharyngeal isthmus during the later stages of embryonic development. Involved in vulval epithelium invagination.
