41. AEBP2 is a DNA-binding transcriptional repressor . 42. This control over the chromatin is brought about and maintained by recruited transcriptional repressors . 43. Flies with an extra dose of CREB repressor could not form lasting memories at all. 44. Repressors bind to operators to prevent transcription.45. During normal growth, the SOS genes are negatively regulated by LexA repressor protein dimers. 46. Gli2 was also found to be a stronger activator while Gli3 was a strong repressor . 47. While repressors E2F4 and 5 do not alter cell proliferation, they mediate G1 arrest. 48. In contrast, FabR acts as a repressor for the transcription of fabA and fabB. 49. Mnt is a transcriptional repressor related to the Myc / Mad family of transcription factors. 50. This gene encodes a transcriptional repressor which represses neuronal genes in non-neuronal tissues.
