This biobrick represents the DNA template for the transcription of a 65 nt shRNA, excluding the promoter. The dsRNA sequence was taken from pUC57-OriLR-deGFP plasmid (BBa_K3407006). It corresponds to 27nt from the eGFP gene (nt 78 to 105), and is the one recognised and processed by Dicer to form siRNA. The shRNA has a single-stranded RNA (ssRNA) loop region designed to be recognised by Fox-1 RBD (<html><a id="6" href="https://parts.igem.org/Part:BBa_K3407004" target="_blank"><b>BBa_K3407004</b></a></html>), containing its “<html><u>UGCAUGU</u><html>” RNA target sequence.

Design Notes

This biobrick represents the DNA template for the transcription of a 65 nt shRNA, excluding the promoter. Trancription was performed with BBa_K3407022. The dsRNA sequence was taken from pUC57-OriLR-deGFP plasmid (BBa_K3407006). It corresponds to 27nt from the eGFP gene (nt 78 to 105), and is the one recognised and processed by Dicer to form siRNA. The shRNA has a single-stranded RNA (ssRNA) loop region designed to be recognised by Fox-1 RBD (BBa_K3407004), containing its “UGCAUGU” RNA target sequence [1]. The dsRNA region contains a GG overhang that would represent the overhang left when mini-3 (BBa_K3407002) cleaves a tshRNA (See iGEM TU Delft 2020, Design - Future perspectives), and that represents a good substrate to process the shRNA by Dicer into a siRNA.
