Anti-CRISPR (acr) promoter inhibitor

This anti-CRISPR-associated 1 (Aca1) protein is the inhibitor of Anti-CRISPR (acr) promoter, it was identified in 2019 (Stanley et al., 2019).

Protein anti-CRISPR-associated 1 (Aca1) is expressed by T7 promoter, Aca1 will subsequently inhibit the anti-CRISPR promoter, so the gene expression downstream anti-CRISPR will be inhibited until Navitoclax (a compound that can inhibit Aca1 found by SUSTech_Shenzhen) is added artificially. Without the inhibition from Aca1, the expression of genes downstream anti-CRISPR promoter will increase significantly. Therefore, protein expression can be regulated artificially.

We characterised the efficiency of this part of inhibiting a downstream promoter, it successfully worked in our composite part BBa_K3423005.The inhibition of Aca1 is measured through green fluorescent protein: SUSTech_ShenzhenGFP.png
