Transcription factors

Transcription factors are proteins encoded by regulatory genes that function by influencing the rate of transcription.

Mechanism of action

Transcription factors are specific proteins that influence the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence.

Gene regulation via transcription factors

Gene regulation can occur at any point during gene expression. However, it most commonly occurs at the level of transcription.

Environmental influence

• When signals from the environment or from other cells activate proteins called transcription factors.
• These proteins are called transcription factors which bind to regulatory regions of a gene.
• This process in turn can increase or decrease the level of transcription.
• Transcription factors control the amount of protein made by a gene.
