Transcription factors.

Explanation:

Transcription factors are the general class of protein that binds to regulatory (i.e., non coding) sequences in DNA. Transcription factors binding to the DNA can either make it more likely that DNA is transcribed, or it can make it less likely that DNA is transcribed. For this reason, transcription factors are often classified as either 'activators' or 'inhibitors' depending on their biologic effect.
