pCrU6.3

pCrU6.3 is a previously characterized RNA polymerase III promoter from the chromosome 8 of Chlamydomonas reinhardtii

The first prerequisite for CRISPR/Cas9 experiments is sgRNA transcription under the control of the RNA polymerase III promoter (RNAPII) . In general, the RNAPII transcription factor binding site is intrinsic to the transcriptional sequence and therefore not amenable to sgRNA transcription. U6snRNA is one of the few examples of sgRNAs with proximal RNAPII promoter elements. Therefore, we used previously characterized U6snRNA sequences from chromosome 8.

Usage

pCrU6.3 was constructed into plasmid pTX2038 and pTX2040 as the promoter of gRNA, and was successfully introduced into Chlamydomonas reinhardtii to obtain the positive transformant.
