Activation domains

Activation domains are specific regions within proteins, often found in transcription factors, that enhance the process of gene expression. Think of them as essential parts of a machine that boost its efficiency. When these domains interact with other molecules, they help initiate or speed up the copying of DNA into RNA, leading to the production of proteins. This is crucial for various biological processes, including growth, response to signals, and cellular development. Understanding activation domains helps researchers explore how genes are regulated and can inform medical research and therapies.
