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

SLC52A2Solute carrier family 52, riboflavin transporter, member 2; Plasma membrane transporter mediating the uptake by cells of the water soluble vitamin B2/riboflavin that plays a key role in biochemical oxidation-reduction reactions of the carbohydrate, lipid, and amino acid metabolism. Humans are unable to synthesize vitamin B2/riboflavin and must obtain it via intestinal absorption. May also act as a receptor for 4- hydroxybutyrate (Probable). (445 aa)    
Predicted Functional Partners:
FFAR2
Free fatty acid receptor 2; G protein-coupled receptor that is activated by a major product of dietary fiber digestion, the short chain fatty acids (SCFAs), and that plays a role in the regulation of whole-body energy homeostasis and in intestinal immunity. In omnivorous mammals, the short chain fatty acids acetate, propionate and butyrate are produced primarily by the gut microbiome that metabolizes dietary fibers. SCFAs serve as a source of energy but also act as signaling molecules. That G protein-coupled receptor is probably coupled to the pertussis toxin- sensitive, G(i/o)-alpha f [...]

FLAD1
Molybdenum cofactor biosynthesis protein-like region; Catalyzes the adenylation of flavin mononucleotide (FMN) to form flavin adenine dinucleotide (FAD) coenzyme. In the C-terminal section; belongs to the PAPS reductase family. FAD1 subfamily.
   
  
 0.678
FBXL6
F-box/LRR-repeat protein 6; Substrate-recognition component of the SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin ligase complex.
   
  
 0.675
SLC25A32
Mitochondrial folate transporter/carrier; Transports folate across the inner membranes of mitochondria. Can also transport FAD across the mitochondrial inner membrane.
   
  
 0.598
ADCK5
Uncharacterized aarF domain-containing protein kinase 5; The function of this protein is not yet clear. It is not known if it has protein kinase activity and what type of substrate it would phosphorylate (Ser, Thr or Tyr).
 
 
  
 0.587
ETFDH
Electron transfer flavoprotein-ubiquinone oxidoreductase, mitochondrial; Accepts electrons from ETF and reduces ubiquinone; Belongs to the ETF-QO/FixC family.
      
 0.526
RFK
Riboflavin kinase; Catalyzes the phosphorylation of riboflavin (vitamin B2) to form flavin-mononucleotide (FMN), hence rate-limiting enzyme in the synthesis of FAD. Essential for TNF-induced reactive oxygen species (ROS) production. Through its interaction with both TNFRSF1A and CYBA, physically and functionally couples TNFRSF1A to NADPH oxidase. TNF- activation of RFK may enhance the incorporation of FAD in NADPH oxidase, a critical step for the assembly and activation of NADPH oxidase.
      
 0.465
TMEM237
Transmembrane protein 237; Component of the transition zone in primary cilia. Required for ciliogenesis; Belongs to the TMEM237 family.
      
 0.455
CPSF1
Cleavage and polyadenylation specificity factor subunit 1; Component of the cleavage and polyadenylation specificity factor (CPSF) complex that plays a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. This subunit is involved in the RNA recognition step of the polyadenylation reaction.
   
  
 0.436
SLC19A3
Thiamine transporter 2; Mediates high affinity thiamine uptake, probably via a proton anti-port mechanism. Has no folate transport activity. Belongs to the reduced folate carrier (RFC) transporter (TC 2.A.48) family.
