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:
a 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
mgtLRegulatory leader peptide for mgtA; Makes mgtA transcription sensitive to intracellular proline levels. Under low levels of proline this protein cannot be fully translated, and a stem loop forms which permits transcription of the downstream mgtA gene (By similarity). (17 aa)    
Predicted Functional Partners:
Magnesium transporter; Mediates magnesium influx to the cytosol. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIIB subfamily.
ryhB-regulated fur leader peptide; Cotranscribed with fur, it is essential for fur translation. The fur ribosomal binding site (RBS) is occluded by the 5'-mRNA secondary structure, which is opened by uof translation.
pyrBI operon leader peptide; Protein involved in pyrimidine nucleotide biosynthetic process.
Chitosugar-induced verified lipoprotein.
Transcription termination factor; 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.
Trehalose 6-phosphate-inducible trehalose regulon transcriptional repressor; Repressor of the treBC operon. It is able to bind trehalose- 6-phosphate and trehalose.
Polyproline-specific translation elongation factor EF-P; Involved in peptide bond synthesis. Alleviates ribosome stalling that occurs when 3 or more consecutive Pro residues or the sequence PPG is present in a protein, possibly by augmenting the peptidyl transferase activity of the ribosome. Beta-lysylation at Lys- 34 is required for alleviation. The Pro codons and their context do not affect activity; only consecutive Pro residues (not another amino acid) are affected by EF-P. Has stimulatory effects on peptide bond formation between ribosome-bound initiator tRNA(fMet) and puromycin, [...]
