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

lprNPossible Mce-family lipoprotein LprN (Mce-family lipoprotein Mce4E); Stimulates the host (mouse) immune response; lipidated protein produced in E.coli stimulates T-cell proliferation in mice previously sensitized with LprN. Spleenocytes from these mice produce increased amounts of TNF-alpha and IFN-gamma, as well as somewhat increased nitric oxide levels, upon subsequent challenge with LprN. Previously sensitized mice infected with M.tuberculosis have an exacerbated disease response, suggesting this lipoprotein may down- regulate the host's immune response. (384 aa)
