In summary, transcription factors regulate gene expression. They do this by interacting directly with a target gene through the DBD. Once the transcription factor binds to DNA, co-regulatory molecules bind the transcription factor at the TAD.This leads to the formation of a gene regulatory complex.n summary, transcription factors regulate gene expression.
