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
XDHXanthine dehydrogenase/oxidase; Key enzyme in purine degradation. Catalyzes the oxidation of hypoxanthine to xanthine. Catalyzes the oxidation of xanthine to uric acid. Contributes to the generation of reactive oxygen species. Has also low oxidase activity towards aldehydes (in vitro). (1333 aa)    
Predicted Functional Partners:
BTN1A1
Butyrophilin subfamily 1 member A1; May function in the secretion of milk-fat droplets. May act as a specific membrane-associated receptor for the association of cytoplasmic droplets with the apical plasma membrane (By similarity). Inhibits the proliferation of CD4 and CD8 T-cells activated by anti-CD3 antibodies, T-cell metabolism and IL2 and IFNG secretion (By similarity); Belongs to the immunoglobulin superfamily. BTN/MOG family.
   
 
 0.998
PNP
Purine nucleoside phosphorylase; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.
   
 
 0.997
GDA
Guanine deaminase; Catalyzes the hydrolytic deamination of guanine, producing xanthine and ammonia; Belongs to the metallo-dependent hydrolases superfamily. ATZ/TRZ family.
 
 
 0.988
BTN2A1
Butyrophilin subfamily 2 member A1.
      
 0.988
BTNL9
Butyrophilin-like protein 9; Butyrophilin like 9; Belongs to the immunoglobulin superfamily. BTN/MOG family.
      
 0.988
BTN2A2
Butyrophilin subfamily 2 member A2; Inhibits the proliferation of CD4 and CD8 T-cells activated by anti-CD3 antibodies, T-cell metabolism and IL2 and IFNG secretion. Belongs to the immunoglobulin superfamily. BTN/MOG family.
      
 0.988
TPMT
Thiopurine S-methyltransferase; Catalyzes the S-methylation of thiopurine drugs such as 6- mercaptopurine (also called mercaptopurine, 6-MP or its brand name Purinethol) and 6-thioguanine (also called tioguanine or 6-TG) using S- adenosyl-L-methionine as the methyl donor. TPMT activity modulates the cytotoxic effects of thiopurine prodrugs. A natural substrate for this enzyme has yet to be identified; Belongs to the class I-like SAM-binding methyltransferase superfamily. TPMT family.
     
 0.974
BTNL3
Butyrophilin-like protein 3; Butyrophilin like 3.
   
  
 0.969
BTNL8
Butyrophilin-like protein 8; May stimulate primary immune response. Acts on T-cell stimulated sub-optimally through the TCR/CD3 complex stimulating their proliferation and cytokine production; Belongs to the immunoglobulin superfamily. BTN/MOG family.
   
  
 0.969
ERMAP
Erythroid membrane-associated protein; Possible role as a cell-adhesion or receptor molecule of erythroid cells; Belongs to the immunoglobulin superfamily. BTN/MOG family.
      
 0.969
