| - | '''Transcriptional activators''' (TA) are proteins which bind to DNA and stimulate nearby gene transcription. TA transcription stimulation is achieved by enhancing RNA polymerase binding or by enhancing the formation of open complex which is required for initiation of transcription. TA bind to a specific DNA sequence in or near an operon via their DNA-binding domain (DBD)<ref>PMID:16464826</ref>. | + | '''Transcriptional activators''' or '''Transcriptional regulators''' (TA) are proteins which bind to DNA and stimulate nearby gene transcription.
