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

ytnMPutative transporter; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter. (300 aa)    
Predicted Functional Partners:
rbfK
RNA-binding cryptic riboflavin kinase regulatory protein; May be directly involved in the regulation of the rib genes. C-terminal part of RibR specifically binds to RFN of the rib leader of the riboflavin biosynthetic operon. The RFN element is a sequence within the rib-leader mRNA reported to serve as a receptor for an FMN- dependent riboswitch. Possibly, RibR produces the comodulator FMN through its own N-terminal flavokinase activity. FMN-activated RibR may stabilize the anti-anti terminator structure of RFN mRNA, causing transcription termination of the rib genes in trans.
