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
rlmA23S rRNA m(1)G745 methyltransferase, SAM-dependent; Specifically methylates the guanosine in position 745 of 23S rRNA (269 aa)    
Predicted Functional Partners:
Nadh:ubiquinone oxidoreductase, fused cd subunit; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient
23S rRNA mG2251 2'-O-ribose methyltransferase, SAM-dependent; Specifically methylates the ribose of guanosine 2251 in 23S rRNA
23S rRNA m(3)Psi1915 pseudouridine methyltransferase, SAM-dependent; Specifically methylates the pseudouridine at position 1915 (m3Psi1915) in 23S rRNA. Specific for fully assembled 70S ribosomes
Trna leu mc34,mu34 2'-o-methyltransferase, sam-dependent; Methylates the ribose at the nucleotide 34 wobble position in the two leucyl isoacceptors tRNA(Leu)(CmAA) and tRNA(Leu)(cmnm5UmAA). Catalyzes the methyl transfer from S-adenosyl-L-methionine to the 2'-OH of the wobble nucleotide. Recognition of the target requires a pyridine at position 34 and N(6)-(isopentenyl)-2-methylthioadenosine at position 37
16S rRNA m(2)G1516 methyltransferase, SAM-dependent; Specifically methylates the guanosine in position 1516 of 16S rRNA
Trna mg18-2'-o-methyltransferase, sam-dependent; Catalyzes the 2'-O methylation of guanosine at position 18 in tRNA. Type II methylase, which methylates only a subset of tRNA species
Trna mc32,mu32 2'-o-methyltransferase, sam-dependent; Catalyzes the formation of 2'O-methylated cytidine (Cm32) or 2'O-methylated uridine (Um32) at position 32 in tRNA Can also methylate adenosine or guanosine, even though these nucleosides are rare or absent at position 32 in the anticodon loop of tRNA
RF-1 and RF-2 N5-glutamine methyltransferase; Methylates the class 1 translation termination release factors RF1/PrfA and RF2/PrfB on the glutamine residue of the universally conserved GGQ motif, i.e. on 'Gln-235' in RF1 and on 'Gln- 252' in RF2
Rnase bn, trna processing enzyme; Zinc phosphodiesterase, which has both exoribonuclease and endoribonuclease activities, depending on the nature of the substrate and of the added divalent cation, and on its 3'-terminal structure. Can process the 3' termini of both CCA-less and CCA-containing tRNA precursors. CCA-less tRNAs are cleaved endonucleolytically after the discriminator base, whereas residues following the CCA sequence can be removed exonucleolytically or endonucleolytically in CCA-containing molecules. Does not remove the CCA sequence. May also be involved in the degradation [...]
Trna m(1)g37 methyltransferase, sam-dependent; Specifically methylates guanosine-37 in various tRNAs
