U6 promoter

U6 promoter is used to drive the expression of homing guide RNA（hgRNA） in lineage tracing for eukaryotic systems. We used it to initiate the transcription of hgRNA(sgRNA). The U6 promoter has a clear transcription start point G. The 5′-TTTTT-3′ sequence located downstream of the promoter is used as a transcription termination signal, and the transcription product will be added at the 3′ end of 2 -4 oligomeric U.
