Overview

Mode of Action (MoA) AlphaFold 3 predicts a direct interaction between Cas2 (https://www.ncbi.nlm.nih.gov/protein/ALU77912.1) and AcrIIA3 (ipTM = 0.7, pTM = 0.72).
Evidence Ectopic expression (ECO_0000017) of acrIIA3 in L. monocytogenes inhibits CRISPR-Cas9 function in a plasmid targeting assay. Binding it supported by computational structure modeling evidence (ECO_0006368).
