Part:BBa_K4409005
trigger-RNA sensor of igRNA (hsa_circ_0001982)_coupled with hsa_circ_0001785 as the guide sequence
It is used as a sensing part of the RNA-interacting guide RNA (igRNA) in our CRISPR-Cas12 system to detect a unique sequence (trigger RNA) of the target circRNA hsa_circ_0001982. This part serves as a switch for the whole circuit. It contains three regions, VR1 region, loop region, and VR2 region. VR1 and VR2 regions complement to VR1’ and VR2’ regions (trigger RNA) of hsa_circ_0001982. Loop region is complementary to the guide of igRNA (hsa_circ_0001785) (BBa_K4409001). When hsa_circ_0001982 is present in the system, VR1 and VR2 regions combine with VR1’ and VR2’ sequences. Thus, loop region unblocks the guide of igRNA (hsa_circ_0001785) (BBa_K4409001) which can then bind with dsDNA(hsa_circ_0001785) (BBa_K4409007) and activate Cas enzyme to cleave DNAs.
