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

nifAMo/Fe nitrogenase specific transcriptional regulator, NifA; Function of strongly homologous gene; regulator. (558 aa)    
Predicted Functional Partners:
rpoN
RNA polymerase sigma-54 factor(RNA polymerase sigma factor 54,11-496); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
