An experimentally introduced gene whose measurable output reports a specified regulatory process. A change in protein output alone cannot distinguish altered transcription, RNA decay and biological translation.

A reporter gene is a gene that researchers use to study the activity of other genes or regulatory sequences. It is typically a gene that encodes a protein producing an easily measurable signal, such as fluorescence or color change, which can be quantitated. Reporter genes are often used in molecular biology and genetics to monitor gene expression, track cellular processes, or evaluate the efficacy of different treatments.
