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

hst-1Bifunctional 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). (852 aa)    
Predicted Functional Partners:
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.
   
 0.990
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.
   
  
 0.922
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.
   
 
 0.912
rib-1
Exostosin-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 [...]

rib-2
Exostosin-2 homolog; Glycosyltransferase required for the biosynthesis of heparan sulfate. Initiates heparan sulfate synthesis by transferring GlcNAc to the (GlcA-Gal-Gal- Xyl-)Ser core linker (GlcNAcT-I activity). In association with rib-1, is also responsible for the alternating addition of beta-1-4-linked glucuronic acid (GlcA) and alpha-1-4-linked N-acetylglucosamine (GlcNAc) units to nascent heparan sulfate chains (GlcNAcT-II and GlcAT-II activities). Required for normal ventral epidermal enclosure during the early stages of embryonic development. In addition, involved in the elon [...]

gpn-1
GlyPicaN; Belongs to the glypican family.
    
 0.814
sdn-1
Probable syndecan; Cell surface proteoglycan that bears heparan sulfate (By similarity). Required for correct mitotic spindle orientation of the ABar blastomere division plane and this may be through modulation of astral microtubule array, and in association with the wnt-signaling proteins mig-5 and dsh-2. Involved in the migration of AQR and PQR neurons, which descend from the Q neuroblasts. Promotes the axon guidance of D-type motor neurons.

CoLlagen with Endostatin domain.

lon-2
LONg; Belongs to the glypican family.
