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.
