Fig 4. Beta-catenin sub-network for transcriptional feedback analysis.
(A) Workflow for identifying beta-catenin transcriptional targets that affect beta-catenin transcriptional activity, thereby participating in positive and/or negative feedback loops. (B) Sub-network of beta-catenin interacting proteins whose expression is regulated by a transcription factor co-activated by beta-catenin (“target-interactors”). Node fill color indicates the effect of the interacting proteins on beta-catenin transcriptional activity. Nodes with heavy borders represent genes for which there is experimental evidence of transcriptional regulation by beta-catenin.
