Die tracrRNA wird trans codiert. Sie wurde erstmals 2011 bei Streptococcus pyogenes beschrieben. Die tracrRNA bindet per Basenpaarung an die crRNA und ist Bestandteil des Ribonukleoproteinkomplexes der meisten Cas-Proteine (beispielsweise Cas9, Cas12b). Der RNA-Doppelstrang aus crRNA und tracrRNA wird über einen Schnitt durch die RNase III in die aktive Form überführt und dient dem CRISPR/Cas als Adapter zur Bindung der zu schneidenden Ziel-DN… SpletEs besteht aus zwei RNAs, die teilweise komplementär sind und durch Basenpaarung zusammengehalten wird. crRNA:tracrRNA bindet an Cas9 und bringt das Protein an die „richtige“ Stelle in der Target-DNA. Dies geschieht durch die Komplementarität zwischen einem Teil der crRNA und der Target-RNA.
