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
rsfSRibosomal silencing factor rsfs; Functions as a ribosomal silencing factor. Addition to isolated ribosomal subunits partially inhibits their association, preventing translation. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8, preventing association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation (105 aa)    
Predicted Functional Partners:
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
This protein binds directly to 23S ribosomal RNA. In the E.coli 70S ribosome it has been modeled to make two contacts with the 16S rRNA of the 30S subunit, forming part of bridges B5 and B8, connecting the 2 subunits . Although the protein undergoes significant rotation during the transition from an initiation to and EF-G bound state, the bridges remain stable. In the 3.5 A resolved structures L14 and L19 interact and together make contact with the 16S rRNA in bridges B5 and B8
Phenylalanyl-trna synthetase operon leader peptide; One of the primary rRNA binding proteins, it binds close to the 5'-end of the 23S rRNA. It is important during the early stages of 50S assembly
Penicillin-binding protein 2, transpeptidase involved in peptidoglycan synthesis; Catalyzes cross-linking of the peptidoglycan cell wall . Responsible for the determination of the rod shape of the cell . Is probably required for lateral peptidoglycan synthesis and maintenance of the correct diameter during lateral and centripetal growth
Large subunit ribosomal protein l27; 50S ribosomal protein L27; Protein involved in structural constituent of ribosome and translation
Nicotinic acid mononucleotide adenylyltransferase, nad(p)-dependent; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD)
Large subunit ribosomal protein l32; 50S ribosomal protein L32; Protein involved in structural constituent of ribosome and translation
annotation not available
Septal ring protein, suppressor of prc, minor lipoprotein; Lytic transglycosylase with a strong preference for naked glycan strands that lack stem peptides
Cell wall shape-determining protein; Peptidoglycan polymerase that is essential for cell wall elongation . Also required for the maintenance of the rod cell shape . Functions probably in conjunction with the penicillin-binding protein 2 (mrdA)
