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

sqv-7UDP-sugar transporter sqv-7; Involved in the import of UDP-glucuronic acid (UDP-GlcA), UDP-N-acetylgalactosamine (UDP-GalNAc) and UDP-galactose (UDP-Gal) from the cytoplasm into the Golgi lumen for the biosynthesis of glycoconjugates that play a pivotal role in development. Involved in the synthesis of chondroitin sulfate and heparan sulfate proteoglycans. Required for embryonic development. Involved in vulva epithelium invagination and embryonic development. Involved in the directed migration of hermaphrodite-specific neurons. Belongs to the TPT transporter family. SLC35D subfamily. (329 aa)    
Predicted Functional Partners:
sqv-3
Xylosylprotein 4-beta-galactosyltransferase; Glycosyltransferase required for the biosynthesis of the tetrasaccharide (GlcA-Gal-Gal-Xyl-)Ser core linker of heparan sulfate and chondroitin sulfate. Required for embryonic development. Involved in vulval epithelium invagination ; Belongs to the glycosyltransferase 7 family.

sqv-5
Chondroitin sulfate synthase sqv-5; Has both beta-1,3-glucuronic acid and beta-1,4-N- acetylgalactosamine transferase activity. The beta- 1,3-glucuronic acid transferase activity is controversial as it is not detected using the purified recombinant enzyme. Adds the first N-acetylgalactosamine(GalNAc) to initiate the chondroitin chain. Transfers glucuronic acid (GlcUA) from UDP-GlcUA and GalNAc from UDP-GalNAc to the non-reducing end of the elongating chondroitin polymer. Together with mig-22, required for chondroitin synthesis. Plays a role in early embryonic development by controlling [...]

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.
   
  
 0.876
srf-3
UDP-galactose/UDP-N-acetylglucosamine transporter srf-3; Acts as a transporter of both UDP-galactose and UDP-N- acetylglucosamine into the Golgi lumen.
   
  
 0.857
coq-4
Ubiquinone biosynthesis protein coq-4, mitochondrial; Component of the coenzyme Q biosynthetic pathway. May play a role in organizing a multi-subunit COQ enzyme complex required for coenzyme Q biosynthesis. Required for steady-state levels of other COQ polypeptides; Belongs to the COQ4 family.
 
      0.850
sqv-4
UDP-glucose 6-dehydrogenase; Involved in the biosynthesis of glycosaminoglycans; hyaluronan, chondroitin sulfate, and heparan sulfate. Belongs to the UDP-glucose/GDP-mannose dehydrogenase family.
