Cre-LoxP recombination system

Cre (from “Cre”ates) recombinase:
- P1 bacteriophage에서 나온 enzyme임
- Substrate DNA에 결합하여,
- 2개의 LoxP sites 사이를 cut out하도록 디자인되었음..

LoxP (from “L”ocus “O”f “X”-over in “P”1 bacteriophage)
- P1 bacteriophage에 있는 34 bp region (ATAAC TTCGT ATAGC ATACA TTATA CGAAG TTAT) 으로 2개의 symmetric한 13bp sequence를 포함함.
- asymmetric 8 bp region때문에 Cre가 deletion, inversion, translocation을 catalyze 하게 됨.
