Disease relevance of ECs5026

  • The Escherichia coli LexA repressor-operator system works in mammalian cells [1].
  • Considerable homology has also been detected between UmuD, MucA, and the COOH-terminal domains of the LexA repressor and the repressors of phage lambda, 434, and P22 [2].
  • To investigate integration site selection, and to possibly influence this process, we have used a model system in which the avian sarcoma virus (ASV) IN, and segments thereof, have been fused to the Escherichia coli LexA repressor protein DNA binding domain (DBD) [3].
