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

sms-3Putative phosphatidylcholine:ceramide cholinephosphotransferase 3; Bidirectional lipid cholinephosphotransferase capable of converting phosphatidylcholine (PC) and ceramide to sphingomyelin (SM) and diacylglycerol (DAG) and vice versa. Direction is dependent on the relative concentrations of DAG and ceramide as phosphocholine acceptors. Directly and specifically recognizes the choline head group on the substrate. Also requires two fatty chains on the choline-P donor molecule in order to be recognized efficiently as a substrate. Does not function strictly as a SM synthase (By similarity). (425 aa)    
Predicted Functional Partners:
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.
     
 0.971
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.
     
 0.968
lagr-1
Probable ceramide synthase lagr-1; Catalyzes the acylation of sphingosine to form ceramides.
     
 0.964
T27F6.6
Putative neutral sphingomyelinase.
   
 
 0.936
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.
