Enhancers

• [[promoters]] of promoters
• instructing the promoter when, where, and at what levels to turn on gene transcription
• reside on open [[chromatin]]
• activated by binding of [[Transcription factor]]
• can be cis (on the same chromosome) or trans (on another chromosome) from the gene they regulate
• each gene can have multiple enhancers
• same enhancer can control different genes
