transactivate

(trăns-ăk′tə-vāt′, trănz-)
tr.v. transacti·vated, transacti·vating, transacti·vates
To stimulate the transcription of (a gene in a host cell) by binding to DNA. Genes can be transactivated naturally by a virus or cellular protein or artificially by the insertion of a transactivator gene and segment of DNA into a cell.
