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

Predicted Functional Partners:
rsmN
Small GTPase.
   
  
 0.884
sgkB
Sphingosine kinase B; Catalyzes the phosphorylation of sphingosine to form sphingosine-1-phosphate (S1P), which probably acts intracellularly as a second messenger perhaps by promoting cell proliferation.
      
 0.843
SglB
Uncharacterized protein.
    
 
 0.818
sptB
Serine palmitoyltransferase 2; Catalytic subunit of serine palmitoyltransferase (SPT), which catalyzes the committed step in the synthesis of sphingolipids, the condensation of serine with palmitoyl CoA to form the long chain base 3-ketosphinganine; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family.
   
  
 0.814
sptA
Serine palmitoyltransferase 1; Component of serine palmitoyltransferase (SPT), which catalyzes the committed step in the synthesis of sphingolipids, the condensation of serine with palmitoyl CoA to form the long chain base 3-ketosphinganine; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family.
   
  
 0.811
sgkA
Sphingosine kinase A; Catalyzes the phosphorylation of sphingosine to form sphingosine-1-phosphate (S1P), which probably acts intracellularly as a second messenger perhaps by promoting cell proliferation. Overexpression of sgkA leads to increased growth rates on solid media and an increased resistance to the antitumor agents cisplatin and carboplatin.
      
 0.793
sglA
Sphingosine-1-phosphate lyase; Cleaves phosphorylated sphingoid bases (PSBs), such as sphingosine-1-phosphate, into fatty aldehydes and phosphoethanolamine (By similarity). Sphingosine-1-phosphate (S1P) probably acts intracellularly as a second messenger perhaps by promoting cell proliferation; the absence of S1P lyase increases its concentration. This leads to increased lateral pseudopod formation as well as defects in the efficiency of chemotaxis. Overexpression of S1P lyase causes decreased growth rates, entry into stationary phase at lower cell density and increased sensitivity to [...]

DDB0190661
Fatty acid 2-hydroxylase; Catalyzes stereospecific hydroxylation of free fatty acids at the C-2 position to produce (R)-2-hydroxy fatty acids, which are building blocks of sphingolipids and glycosphingolipids common in neural tissue and epidermis. Plays an essential role in the synthesis of galactosphingolipids of the myelin sheath. Responsible for the synthesis of sphingolipids and glycosphingolipids involved in the formation of epidermal lamellar bodies critical for skin permeability barrier. Participates in the synthesis of glycosphingolipids and a fraction of type II wax diesters i [...]
   
 
 0.739
ksrA-1
3-ketodihydrosphingosine reductase; Catalyzes the reduction of 3-ketodihydrosphingosine (KDS) to dihydrosphingosine (DHS).
     
 0.694
DesA
Lipid_DES domain-containing protein.
   
 0.668
