Transcriptional activator proteins may control the level of transcription of eukaryotic genes by bind to promoters that enhance or regulate the transcription.
Repressors may control the level of transcription of eukaryotic genes by binding to DNA sequences that work either as silencers or promoters in order to inhibit the transcription impeding the access to where the transcriptional activator proteins may bind.
