Repressors are regulator proteins that inhibit transcription initiation at gene promoters in order to modulate gene expression in response to variations in environmental conditions. The molecular and biochemical mechanisms by which such repression is achieved vary widely, and are often modulated by signal molecules which act by altering their mechanism of action.
- DNA looping;
- contact inhibition;
- dual regulator;
- differential contact;
- steric hindrance
