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

Score
SMPDL3AAcid sphingomyelinase-like phosphodiesterase 3a; Has in vitro nucleotide phosphodiesterase activity with nucleoside triphosphates, such as ATP. Has in vitro activity with p-nitrophenyl-TMP. Has lower activity with nucleoside diphosphates, and no activity with nucleoside monophosphates. Has in vitro activity with CDP-choline, giving rise to CMP and phosphocholine. Has in vitro activity with CDP-ethanolamine. Does not have sphingomyelin phosphodiesterase activity. Belongs to the acid sphingomyelinase family. (453 aa)    
Predicted Functional Partners:
BRINP1
BMP/retinoic acid-inducible neural-specific protein 1; Inhibits cell proliferation by negative regulation of the G1/S transition. Mediates cell death which is not of the classical apoptotic type and regulates expression of components of the plasminogen pathway; Belongs to the BRINP family.
   
  
 0.975
PRF1
Perforin-1; Plays a key role in secretory granule-dependent cell death, and in defense against virus-infected or neoplastic cells. Plays an important role in killing other cells that are recognized as non-self by the immune system, e.g. in transplant rejection or some forms of autoimmune disease. Can insert into the membrane of target cells in its calcium-bound form, oligomerize and form large pores. Promotes cytolysis and apoptosis of target cells by facilitating the uptake of cytotoxic granzymes. Belongs to the complement C6/C7/C8/C9 family.
      
 0.711
TTC9C
Tetratricopeptide repeat domain 9C; Belongs to the TTC9 family.
      
 0.529
VWDE
Von Willebrand factor D and EGF domains.
      
 0.492
BTBD10
BTB/POZ domain-containing protein 10; Plays a major role as an activator of AKT family members by inhibiting PPP2CA-mediated dephosphorylation, thereby keeping AKTs activated. Plays a role in preventing motor neuronal death and accelerating the growth of pancreatic beta cells.
   
  
 0.464
GSTT4
Glutathione S-transferase theta-4; Conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles. Belongs to the GST superfamily. Theta family.
      
 0.445
CDC40
Pre-mRNA-processing factor 17; Required for pre-mRNA splicing as component of the activated spliceosome.
   
  
 0.437
OTOP3
Proton channel OTOP3; Proton-selective channel that specifically transports protons into cells. Proton-selective channel activity is probably required in cell types that use changes in intracellular pH for cell signaling or to regulate biochemical or developmental processes. Belongs to the otopetrin family.
      
 0.418
SQOR
Sulfide:quinone oxidoreductase, mitochondrial; Catalyzes the oxidation of hydrogen sulfide with the help of a quinone, such as ubiquinone, giving rise to thiosulfate and ultimately to sulfane (molecular sulfur) atoms. Requires an additional electron acceptor; can use sulfite, sulfide or cyanide (in vitro). Belongs to the SQRD family.
   
  
 0.410
SMPD4
Sphingomyelin phosphodiesterase 4; Catalyzes the hydrolysis of membrane sphingomyelin to form phosphorylcholine and ceramide. May sensitize cells to DNA damage-induced apoptosis.
