Cargo (guide RNA - switch- Cas12k- MCP/ADAR)

Description and Usage

The first component of Cargo is the CRISPR system, where we uses guide RNA to direct our Cas12k toward the BAFF-R gene in auto-reactive B-cells, and the second component is the DART V ADAR switch, where we uses ADAR enzyme to convert Adenosine into Inosine, causing a change in the switch condition from off to on status, but ADAR enzyme works only in the presence of complementary mRNA in the target cell to the sensor within the switch that contains the stop codon (UAG) of auto-reactive B-cells. This stop codon contains a mismatched Adenosine (A) group with the complementary mRNA; this group is hybridized by ADAR enzyme activity and converts to an Inosine group (I); thus, the stop codon sequence is disturbed in this condition and our cargo will be translated as shown in figure 1.

Figure 1: This figure illustrates the design of our biological circuit expressing our therapeutic agent under the control of the VP64 transcription module that regulates the activity of the ZF21.16minCMV promoter.
