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
ynfNQin prophage; protein ynfn; Uncharacterized protein YnfN; Phage or Prophage Related (51 aa)    
Predicted Functional Partners:
Fructose-like pts system eiib component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II FryABC PTS system is involved in fructose transport
AI-2 transport protein TqsA; Controls the transport of the quorum-sensing signal AI-2 either by enhancing its secretion or inhibiting its uptake and consequently represses biofilm formation and motility and affects the global gene expression in biofilms
Qin prophage; cold shock protein cspi; Cold shock-like protein
Gdp-d-mannose dehydratase, nad(p)-binding; Catalyzes the conversion of GDP-D-mannose to GDP-4-dehydro-6- deoxy-D-mannose
Palmitoleoyl-acyl carrier protein (acp)-dependent acyltransferase; Catalyzes the transfer of palmitoleate from palmitoleoyl-acyl carrier protein (ACP) to Kdo(2)-lipid IV(A) to form Kdo(2)- (palmitoleoyl)-lipid IV(A). Required for the biosynthesis of a distinct molecular species of lipid A, which is present only in cells grown at low temperatures. It may confer a selective advantage to cells growing at lower temperatures by making the outer membrane a more effective barrier to harmful chemicals
Branched-chain amino acid aminotransferase; Acts on leucine, isoleucine and valine
Qin prophage; protein gnsb; Overexpression increases levels of unsaturated fatty acids and suppresses both the temperature-sensitive fabA6 mutation and cold- sensitive secG null mutation
Transcription termination factor rho; Facilitates transcription termination by a mechanism that involves Rho binding to the nascent RNA, activation of Rho's RNA- dependent ATPase activity, and release of the mRNA from the DNA template. RNA-dependent NTPase which utilizes all four ribonucleoside triphosphates as substrates
