mediator complex

The mediator complex is a group of proteins that act as a bridge between gene-specific regulators (like transcription factors) and the cellular machinery responsible for copying DNA into RNA. It helps ensure that genes are turned on or off at the right time by transmitting signals from regulators to the gene's core machinery, facilitating accurate gene expression. Think of it as a coordinator or mediator that oversees the communication between genetic switches and the machines that read the genetic code, ensuring the proper functioning of cells.
