Transcriptional Activators

Transcriptional activators are proteins that help turn on specific genes in a cell. They bind to particular regions of DNA near the gene they regulate and recruit other molecules, such as enzymes and machinery, that facilitate the process of copying the gene’s instructions into messenger RNA (mRNA). This mRNA then serves as a template for making proteins. By controlling when and how strongly genes are expressed, transcriptional activators play a crucial role in development, cellular function, and response to environmental signals. They are essential for ensuring that cells produce the right proteins at the right times.
