STRINGSTRING
STRING protein interaction network
Nodes:
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:
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
Others
textmining
co-expression
protein homology

Predicted Functional Partners:
cheB2
Protein glutamate-methylesterase; Involved in chemotaxis. Part of a chemotaxis signal transduction system that modulates chemotaxis in response to various stimuli. Catalyzes the demethylation of specific methylglutamate residues introduced into the chemoreceptors (methyl-accepting chemotaxis proteins or MCP) by CheR. Also mediates the irreversible deamidation of specific glutamine residues to glutamic acid. Belongs to the CheB family.

CHEMOTAXIS INVOLVES BOTH A PHOSPHORYLATION-DEPENDENT EXCITATION AND A METHYLATION-DEPENDENT ADAPTATION. CHEV AND CHEW FUNCTION TOGETHER TO COUPLE CHEA ACTIVATION TO METHYL-ACCEPTING CHEMOTAXIS PROTEIN RECEPTOR STATUS AND POSSIBLE CHEA-DEPENDENT PHOSPHORYLATION OF CHEV CONTRIBUTES TO ADAPTATION; High confidence in function and specificity.

tcp
Putative citrate chemoreceptor protein; Salmonella typhimurium shows an attractant response to citrate and a repellent response to phenol, and a chemoreceptor mediating these responses has been identified and named Tcp (taxis to citrate and away from phenol). Similar to sprot|MCPC_SALTY (32%)and to trembl|Q82TM2.

tsr
The Escherichia coli chemoreceptor Tsr mediates tactic responses to serine, repellents, and changes in temperature. Similar to sprot|MCP1_ECOLI (31%)and to trembl|Q7NSI6 (36%). Bacterial chemotactic-signal transducers are proteins that respond to changes in the concentration of attractants and repellents in the environment, and transduce a signal from the outside to the inside of the cell. These proteins undergo two covalent modifications: deamidation and reversible methylation. Attractants increase the level of methylation while repellents decrease it. The methyl groups are added by t [...]
