Transcription factors control gene expression by regulating transcription initiation or transcription elongation. Transcription initiation is regulated by DNA-binding proteins, whereas transcription elongation can be controlled by DNA-binding proteins ("transcriptional roadblocks") or RNA-binding proteins (transcription termination/ antitermination).

Transcription factors can be grouped according to their mode of interaction with nucleic acids (DNA-or RNA-binding proteins) and also according to the mechanism by which they perceive the signal.
