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

F33D4.4Putative sphingolipid delta(4)-desaturase; Acts as a sphingolipid delta(4)-desaturase; Belongs to the fatty acid desaturase type 1 family. DEGS subfamily. (360 aa)    
Predicted Functional Partners:
F53B1.2
Sphingomyelin synthase-related 1.
      
 0.952
sms-1
Phosphatidylcholine:ceramide cholinephosphotransferase 1; Sphingomyelin synthases synthesize the sphingolipid, sphingomyelin, through transfer of the phosphatidyl head group, phosphatidylcholine, on to the primary hydroxyl of ceramide. The reaction is bidirectional depending on the respective levels of the sphingolipid and ceramide.
   
 
 0.947
T27F6.6
Putative neutral sphingomyelinase.
     
 0.937
hyl-1
Ceramide synthase hyl-1; Catalyzes the acylation of sphingosine to form ceramides. Exhibits substrate preference for fatty acyl-coA chains containing 24 and 26 carbons.
   
 0.936
hyl-2
Ceramide synthase hyl-2; Catalyzes the acylation of sphingosine to form ceramides. Exhibits substrate preference for fatty acyl-coA chains containing 20 and 22 carbons. Required for adaptation of the nematode to anoxia. Anoxia tolerance may require one or more of the ceramide species that are either specifically or preferentially synthesized by hyl-2, and seems to be effected by a pathway that is parallel to that involving daf-2.
   
 0.936
Y37E11AM.3
Uncharacterized protein; Belongs to the short-chain dehydrogenases/reductases (SDR) family.
   
 
 0.936
lagr-1
Probable ceramide synthase lagr-1; Catalyzes the acylation of sphingosine to form ceramides.
   
 0.936
sphk-1
Sphingosine kinase 1; Catalyzes the phosphorylation of sphingosine to form sphingosine 1-phosphate (SPP), a lipid mediator with both intra- and extracellular functions. Also acts on sphinganine (By similarity). Required for neurotransmitter release from neuromuscular junctions. Acts by recruiting the synaptic vesicle priming protein unc-13 to synapses (Probable).
   
 0.934
cgt-3
Ceramide glucosyltransferase 3; Catalyzes the first glycosylation step in glycosphingolipid biosynthesis, the transfer of glucose to ceramide. Seems to be the major active form in the nematode.
   
 
 0.923
cerk-1
Ceramide kinase 1; Catalyzes the phosphorylation of ceramide to form ceramide 1- phosphate.
   
 0.922
