Definitions for "Transactivation"
Activation of transcription by the binding of a transcription factor to a DNA regulatory sequence.
a situation in which one gene product causes a different gene to be activated.
Transactivation is a technique used in molecular biology to control gene expression by stimulating transcription. During transactivation, the transactivator gene and special promoter regions of DNA are inserted into the genome at areas of interest. The transactivator gene expresses a transcription factor that binds to specific promoter region of DNA.
