There are two main strategies for the induction of transcription: a strong promoter is negatively controlled by a repressor protein and induction of transcription is effected by an inducer (a ligand that inactivates the repressor).
Proximal promoters and enhancers are both sites for transcription factors to bind as well. Proximal promoters are about 200 base pairs upstream of the start site. Enhancers are further away from the start site, and can be found up to 50,000 base pairs up or downstream of the site.
