This device contains loci that can code for small RNAs that are able to target the dCAS9 protein [https://parts.igem.org/Part:BBa_K1150000] to any desired locus containg a so-called PAM seqeunce.  It consists of a human H1 promoter driving the expression of the tracrRNA which mediates the interaction between the dCAS9 protein and the second RNA, the crRNA.  This crRNA gives rise to the specific binding of dCAS9 to DNA and is under control of the human U6 promoter.

This device contains loci that can code for small RNAs that are able to target the dCAS9 protein [1] to any desired locus containg a so-called PAM seqeunce. It consists of a human H1 promoter driving the expression of the tracrRNA which mediates the interaction between the dCAS9 protein and the second RNA, the crRNA. This crRNA gives rise to the specific binding of dCAS9 to DNA and is under control of the human U6 promoter. The 30bp target site can be inserted by simply opening the plasmid with BbsI and ligating it into the plasmid. The flanking direct repeats (DR) will mediate interaction with the tracrRNA. \\ \\ Multiple target sites can be combined on one plasmid by using the BioBrick standard and enables to target multiple loci at once with a small amount of plasmids. \\ The very minimalistic pSB1C3 backbone guarantees strong expression of the RNAs, which are suspected to be the limiting factor of dCAS9 interaction. \\ This plasmid should be used in combination of dCAS9 effector proteins, that can be found in the registry, e.g. [2] or [3].

An efficient tool for designing target sites can be found at Freiburg 2013 teams website.
