Project description
Novel platform to shed light on CRISPR adaptation and bacterial immunity to invading viruses
Most people have by now at least heard about 'CRISPR'. Over the last decade, this simple and affordable technique for gene editing in vivo with its potential for gene therapy of diseases has taken the world by storm. The EU-funded CRISPRsition project is taking us back to its humble origins. Clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) proteins are part of the adaptive immune system in prokaryotes. Bacteria use it to preserve a 'memory' of invasion by a phage by splicing a piece of its invading phage's nucleic acids into the CRISPR array in a process called adaptation. CRISPRsition plans to deliver a platform that identifies relevant parts of bacterial and phage genomes with potential for novel 'antibiotic' therapy.
Objective
The CRISPR-Cas system has been extensively studied for its ability to cleave DNA. In contrast, studies of the ability of the system to acquire and integrate new DNA from invaders as a form of prokaryotic adaptive immunity, have lagged behind. This delay reflects the extreme enthusiasm surrounding the potential of using the system’s cleavage capabilities as a genome editing tool. However, the enormous potential of the adaptation process can and should arouse a similar degree of enthusiasm. My lab has pioneered studies on the CRISPR adaptation process by establishing new methodologies, and applying them to demonstrate the essential role of the proteins and DNA elements, as well as the molecular mechanisms, operating in this process. In this project, I will establish novel platforms for studying adaptation and develop them into biotechnological applications and research tools. These tools will allow me to identify the first natural and synthetic inhibitors of the adaptation process. This, in turn, will provide genetic tools to control adaptation, as well as advance the understanding of the arms race between bacteria and their invaders. I will also harness the adaptation process as a platform for diversifying genetic elements for phage display, and for extending phage recognition of a wide range of hosts. Lastly, I will provide the first evidence for an association between the CRISPR adaptation system and gene repression. This linkage will form the basis of a molecular scanner and recorder platform that I will develop and that can be used to identify crucial genetic elements in phage genomes as well as novel regulatory circuits in the bacterial genome. Together, my findings will represent a considerable leap in the understanding of CRISPR adaptation with respect to the process, potential applications, and the intriguing evolutionary significance.
