STRING protein interaction network
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:
some 3D structure is known or predicted
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
protein homology
Your Input:
Gene Fusion
betITetr/acrr family transcriptional regulator, transcriptional repressor of bet genes; Repressor involved in the biosynthesis of the osmoprotectant glycine betaine. It represses transcription of the choline transporter BetT and the genes of BetAB involved in the synthesis of glycine betaine (195 aa)    
Predicted Functional Partners:
Betaine aldehyde dehydrogenase, nad-dependent; Involved in the biosynthesis of the osmoprotectant glycine betaine. Catalyzes the reversible oxidation of betaine aldehyde to the corresponding acid. It is highly specific for betaine and has a significantly higher affinity for NAD than for NADP
Choline/glycine/proline betaine transport protein; High-affinity uptake of choline driven by a proton-motive force
Choline dehydrogenase, a flavoprotein; Involved in the biosynthesis of the osmoprotectant glycine betaine. Catalyzes the oxidation of choline to betaine aldehyde and betaine aldehyde to glycine betaine at the same rate
Lysr family transcriptional regulator, cyn operon transcriptional activator; Positively regulates the cynTSX operon, and negatively regulates its own transcription. Binds specifically to the cynR-cynTSX intergenic region
Iclr family transcriptional regulator, mhp operon transcriptional activator; Activator of the mhpABCDFE operon coding for components of the 3-hydroxyphenylpropionate degradation pathway
Padr family putative transcriptional regulator; Represses the expression of YqjH which is involved in iron homeostasis under excess nickel conditions. Also represses its own expression
Tetr/acrr family transcriptional regulator, regulator of cefoperazone and chloramphenicol sensitivity; Regulates transcription of the cecR-ybhGFSR operon and the rhlE gene, which altogether are involved in the control of sensitivity to cefoperazone and chloramphenicol. Represses the cecR-ybhGFSR operon and activates the rhlE operon. Acts by binding to a palindromic sequence within the intergenic spacer located between these two divergently transcribed operons
Lysr family transcriptional regulator, glycine cleavage system transcriptional activator; Regulatory protein for the glycine cleavage system operon (gcv). Mediates activation of gcv by glycine and repression by purines. GcvA is negatively autoregulated. Binds to three sites upstream of the gcv promoter
Tetr/acrr family transcriptional regulator, fatty acid biosynthesis regulator; Binds the promoter region of at least fabA and fabB, but probably not yqfA . Represses the transcription of fabA and fabB, involved in unsaturated fatty acid (UFA) biosynthesis . By controlling UFA production, FabR directly influences the physical properties of the membrane bilayer
Deor family transcriptional regulator, ulag and ulaabcdef operon transcriptional repressor; Represses ulaG and the ulaABCDEF operon. Two ulaR binding sites have been identified in each promoter. Full activity requires simultaneous interaction of UlaR with both divergent promoters and seems to be dependent on repressor-mediated DNA loop formation, which is helped by the action of integration host factor
