What is Investigation of the cyclic oligoadenylate signaling pathway of type III CRISPR systems about?
Type III CRISPR effector complexes utilize a bound CRISPR RNA (crRNA) to detect the presence of RNA from invading mobile genetic elements in the cell. This RNA binding results in the activation of two enzymatic domains of the Cas10 subunit-the HD nuclease domain, which degrades DNA, and PALM/cyclase domain. The latter synthesizes cyclic oligoadenylate (cOA) molecules by polymerizing ATP, and cOA acts as a second messenger in the cell, switching on the antiviral response by activating host ribonucleases and other proteins. In this chapter, we focus on the methods required to study the biochemistry of this recently discovered cOA signaling pathway. We cover protein expression and purification, synthesis of cOA and its linear analogues, kinetic analysis of cOA synthesis and cOA-stimulated ribonuclease activity, and small molecule detection and identification with thin-layer chromatography and mass spectrometry. The methods described are based on our recent studies of the type III CRISPR system in Sulfolobus solfataricus, but are widely applicable to other type III systems.
