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

mscMMechanosensitive channel protein, miniconductance; Mechanosensitive channel that protects cells against hypoosmotic stress when highly overexpressed. Gates spontaneously in response to increased membrane tension (1107 aa)    
Predicted Functional Partners:
Phosphatidylserine decarboxylase proenzyme; Catalyzes the formation of phosphatidylethanolamine (PtdEtn) from phosphatidylserine (PtdSer). Only decarboxylates the lipid-linked form of the serine moiety, and not serine alone or derivatives like phosphoserine or glycerophosphoserine
Mechanosensitive channel protein, intermediate conductance; Mechanosensitive channel that protects cells against hypoosmotic stress when highly overexpressed
Mechanosensitive channel protein, miniconductance; Mechanosensitive channel of miniconductance that confers protection against mild hypoosmotic shock. Overexpression confers protection against severe shocks
Fumarate reductase (anaerobic), membrane anchor subunit; Seems to be involved in the anchoring of the catalytic components of the fumarate reductase complex to the cytoplasmic membrane
Mechanosensitive channel protein, high conductance; Mechanosensitive channel that opens in response to stretch forces in the membrane lipid bilayer. Forms a nonselective ion channel with a conductance of about 4 nanosiemens. Participates in the regulation of osmotic pressure changes within the cell. Opens at a pressure just below that which would cause cell disruption and death. The force required to trigger channel opening depends on the membrane lipids composition
Ribosome biogenesis gtpase / thiamine phosphate phosphatase; One of at least 4 proteins (Era, RbfA, RimM and RsgA/YjeQ) that assist in the late maturation steps of the functional core of the 30S ribosomal subunit Binds the 30S subunit contacting the head, platform, and rRNA helix 44, which may assist the last maturation stages . Removes RbfA from mature, but not immature 30S ribosomes in a GTP- dependent manner; 95% removal in the presence of GTP, 90% removal in GMP-PNP and 65% removal in the presence of GDP Circulary permuted GTPase that catalyzes rapid hydrolysis of GTP with a slow c [...]
Hybrid sensory histidine kinase, in two-component regulatory system with uvry; Member of the two-component regulatory system UvrY/BarA involved in the regulation of carbon metabolism via the CsrA/CsrB regulatory system. Phosphorylates UvrY, probably via a four-step phosphorelay
Involved in the degradation of certain denaturated proteins, including DnaA, during heat shock stress
Mechanosensitive channel protein, intermediate conductance, k+ regulated; Mechanosensitive channel that opens in response to membrane tension and specific ionic conditions. Requires high concentrations of external K(+), NH(4)(+), Rb(+) or Cs(+) to gate. May participate in the regulation of osmotic pressure changes within the cell, although it does not appear to have a major role in osmolarity regulation. Forms an ion channel of 1.0 nanosiemens conductance. The channel can remain active for between 30 seconds and over 3 minutes; it does not desensitize upon extended pressure. Its activi [...]
Outer membrane pore protein n, non-specific; Forms pores that allow passive diffusion of small molecules across the outer membrane (By similarity). Non-specific porin
