Abstract
The role of gene regulation is to ensure that gene products, such as enzymes, structural proteins, and RNA molecules, are synthesized when they are needed and in proper amounts. The premier step of gene regulation is at the level of transcription initiation, achieved most often by proteins encoded by genes called 'regulatory genes'. Here, we summarize the structure and function of gene regulators and basic mechanisms by which they achieve their goals.
