Usage and Biology

'dead' CAS13a 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 a diagnostic restriction digest using EcoR1 and Pst1 on a 1% agarose gel using electrophoresis.
