Usage and Biology

dead CAS13a (or dCas13) with a double HEPN nuclease 1 and 2 inactive mutation, linked to a green fluorescent protein (wtGFP) via a linker sequence (ggctcctccggc). On the N-terminal and the C-terminal of the construct there are nuclear localization sequences (NLS; DNA sequence: cccaagaaaaaacgcaaggtg. Amino acid sequence: PKKKRKV) that will reduce background noise when expressed and used in mammalian cell lines.

When supplied with a guide RNA (gRNA), this enzyme will process it into a CRISPR RNA (crRNA). The crRNA contains a sequence that is complementary to the RNA it is targetting.


Validation

The part was validated with two screening primers 200bp up- and downstream of insert and then seperated on a 1% agarose gel using electrophoresis.
