Transcription factors
Transcription factors are proteins that help regulate gene expression by binding to specific DNA sequences. They act like switches that turn genes on or off, influencing how cells function and develop. When a transcription factor attaches to a gene, it can promote or inhibit the production of messenger RNA (mRNA), which is the first step in making proteins. By controlling which genes are active, transcription factors play a crucial role in various biological processes, including growth, immune response, and adaptation to environmental changes. Understanding these factors is essential for insights into health and disease.

Transcription factors are proteins that regulate the process of turning specific genes on or off in cells. They bind to DNA near genes and help control whether those genes are expressed, meaning whether the instructions in the gene are used to make proteins. This regulation is vital for processes like cell growth, differentiation, and response to environmental signals. By influencing gene expression, transcription factors play key roles in development, immune responses, and disease behavior, including cancer. Essentially, they act as conductors in the orchestra of genetic activity, ensuring that the right genes are activated at the right times.
