Regulatory Relationships from Systems Biology
  • BioCyc

    Gene interactions based on ChIPSeq and Transcription Factor Over-Expression (TFOE) (Systems Biology)

    NOTE: Green edges represent the connected genes being classified as differentially essential as a result of the middle gene being knocked out. These interactions are inferred based on RNASeq.

    Interactions based on ChIPSeq data

  • Interactions based on ChIPSeq data (Minch et al. 2014)

    SymbolVapB12jlewWe report the heterologous toxicity of these TA loci in Escherichia coli and show that only a few of the M. tuberculosis-encoded toxins can inhibit E. coli growth and have a killing effect. This killing effect can be suppressed by coexpression of the cognate antitoxin.
