Introduction to CRISPR and Cas9

From UBC 2013: CRISPRs (Clustered Regularly Interspaced Short PalindromicRepeats) are specific regions in some bacterial and archaeal genomes that, together with associated Cas (CRISPR-associated) genes, function as an adaptive immune system in prokaryotes. While the specific ‘adaptive’ nature of this immunity is still under investigation, it is known that exogenous DNA is processed by Cas proteins into short (~30 base pair) sequences that are adjacent to the Protospacer Adjacent Motif (PAM) site. These short pieces of DNA are then incorporated into the host genome between repeat sequences to formspacer elements. The repeat-spacer-repeat array is constitutively expressed (pre-CRISPR RNAs or pre-crRNAs) and processed by Cas proteins to form small RNAs (crRNAs). The small RNAs are then loaded into Cas proteins and act to guide them to initiate the sequence-specific cleavage of the target sequence.

Background from Freiburg 2013: Hidden as an uncharacterized E. coli locus for more than 15 years, Barrangou et al. identified the CRISPR (Clusterd Regularly Interspaced Short Palindromic Repeats) array as a previously unknown adaptive prokaryotic immune system. Almost half of all prokaryotes make use of this defense mechanism against unselective uptake through natural transformation, phage DNA transduction or horizontal gene transfer by conjugation. Invasive DNA or even RNA can be specifically recognized and efficiently cleaved. This unique feature results from the interaction of non-coding RNAs and CRISPR associated (Cas) proteins. From a wide range of known CRISPR subtypes we used CRISPR type II b of S. pyogenes.

The recognition and degradation of invasive DNA by CRISPR/Cas type II occurs in three steps:

1. Acquisition: Invasive DNA is recognized via a protospacer adjacent motif (PAM) – the sequence NGG. A short sequence downstream of the PAM sequence is then integrated into the host CRISPR array and is termed spacer. Spacer sequences transcribe for CRISPR RNAs(crRNAs) which help to cleave sequence-specific invasive DNA. These sequences are located between short palindromic repeats, which are neccessary for the functionality of the crRNAs.
2. Expression/Transcription: The Cas9 endonuclease is expressed. CRISPR array is then transcribed and processed by RNAse III into crRNAs. These contain the complementary spacer sequence and the direct repeat sequence. The crRNA guides the Cas9 protein specifically to invasive DNA sequences. Furthermore trans-activating crRNAs (tracrRNA) are transcribed and bind to the direct repeat part of the crRNA. The tracrRNA is necessary for the formation of a Cas9-RNA complex.
3. Interference: Repeatedly invading DNA, which has been integrated into the CRISPR locus, is detected by the RNA-protein complex and cleaved by Cas9.

Each of these teams have worked on CRISPR based systems for at least some part of their projects. Below, you'll find abstracts for each team, direct links to their CRISPR pages and references. Here is the list of 2013 iGEM teams who worked on CRISPR in their projects:

Abstract: The past decade has seen the emergence of robust bioprocessing strains engineered to synthesize discrete molecular products. The next-generation of strains could be “programmable,” with on demand generation of molecules within a bioreactor e.g. a yogurt fermentation capable of making any combination of flavouring, nutrients or pharmaceuticals. While merging all this potential into single hosts seems efficient, it would also bring added risk in the case of a process failure due to bacteriophage infection. Here, we not only rationally design widespread immunity to phage infection, but also hack this immunity system to yield programmable biosynthesis at the community level. We demonstrate this by building both broadly and specifically neutralizing CRISPR systems that were paired with biosynthetic capabilities for vanillin, caffeine and cinnamaldehyde production. Eventually, a fermentative process could exist that is vaccinated to phage infection but susceptible to targeted phage addition that results in a programmable probiotic – or ultrabiotic.

Chiba 2013

CRISPRi used by the Chiba team

Abstract: In nature, there exist a variety of magnetotactic bacteria. Recently, it was reported that non-magnetotactic cells such as yeast can be magnetized to some extent. We set the goal to transform E. coli into those that are attracted by magnets. By magnetizing E. coli, the cell harvesting process will be much simpler and more economical than the conventional processes such as centrifugation and filtration. To this end, we are conducting three itemized projects. (1) modification of iron transportation network to import as much Fe ions as possible in E. coli, (2) sequestering/ storing iron into human ferritin, and (3) converting cytosolic space from reducing to oxidizing in order to elevate Fe(II)/ Fe(III) ratio within. Because all such manipulations significantly impact the physiology of the host cell, we are establishing the BioBrick platform that enables the temporal knockdown of multiple genes using recently control technology such as CRISPRi.

Duke 2013

Abstract: Synthetic gene circuits have the potential to revolutionize gene therapies and bio-industrial methods by allowing predictable, customized control of gene expression. Bistable switches and oscillators, key building blocks of more complex gene networks, have been constructed using naturally occurring and well-characterized regulatory elements. In order to expand the versatility and variety of these circuits, we designed and constructed gene networks using artificial transcription factors (ATFs). The ATFs are of two classes: inhibitory TAL proteins and a catalytically inactive dCas9 protein with small guide RNA elements, each orthogonal to the yeast genome. Using mathematical modeling, we determined the parameters expected to create bistability and oscillation, using tandem binding site kinetics to achieve cooperativity. Based on these results, we assembled a library of plasmids containing ATFs, binding sites, regulatory elements, and fluorescent reporters. We then integrated these genes into the genome of Saccharomyces cerevisiae and are currently characterizing them using flow cytometry.

Abstract: Our Team developed a universal toolkit, termed uniCAS, that enables customizable gene regulation in mammalian cells. Therefore, we engineered the recently discovered and highly promising CRISPR/Cas9 system. The regulation is based on the RNA-guided Cas9 protein, which allows targeting of specific DNA sequences. Our toolkit comprises not only a standardized Cas9 protein, but also different effector domains for efficient gene activation or repression. We further engineered a modular RNA plasmid for easy implementation of RNA guide sequences. As an additional feature, we established an innovative screening method for assessing the functionality of our uniCAS fusion proteins. Single genes and even whole genetic networks can be modified using our uniCAS toolkit. We think that our toolbox of standardized parts of the CRISPR/Cas9 system offers broad application in research fields such as tissue engineering, stem cell reprogramming and fundamental research.

Abstract: Coordinating behavior across cell populations to form synthetic tissues requires spacial communication between individual cells. While there has been some success engineering single signals, sending multiple signaling elements spanning spatial scales for multicellular coordination remains a significant hurdle. Here, we describe a method for mammalian cell-cell communication utilizing engineered exosomes containing miRNA or protein signals. First, we demonstrate selectively packaging signaling miRNAs (miR-451 and miR-503) and synthetic fusion proteins (GFP, Cas9, and Cre recombinase each individually fused to the oligomerizing membrane targeting domain Acyl-TyA) into exosomes within cells engineered with sender genetic circuits. Next, we demonstrate that these miRNA and protein signals can modulate gene expression within cells engineered with receiver genetic circuits. Finally, we present preliminary cell-cell signaling results on populations of cocultured sender and receiver cells. Our method may enable multiplexed communication among populations of various cell types and the creation of sophisticated synthetic tissues.

Abstract: Most bacteria and archaea can resist invading DNA and/or RNA elements via the clusters of regularly interspaced short palindromic repeats (CRISPRs).It is believed that the integrated CRISPR sequences have the ability to form a genetic memory which prevents the host from being infected.The memory exist as a DNA library in genome, artificially modified to set its target. The CRISPRs and Cas (CRISPR-associated) interact and form this prokaryotic adaptive immune system. Cas9, as a core of CRISPR system, can play a role of targeted-attacking gene "missiles". Therefore, we build a sort of plasmids, loading CRISPR system, to realize the "killing" of harmful genes and/or organisms.

Abstract: We are testing new weapons for the global war against Mycobacterium tuberculosis (MTb), a pathogen that infects nearly 2 billion people. Our 4 synergistic projects aim to help in the prevention, diagnosis, and treatment of tuberculosis. 1) We are reproducing an essential MTb metabolic pathway in E. coli, where it can be easily and safely targeted in a drug screen. 2) We are building a phage-based biosensor to allow the rapid diagnosis specifically drug-resistant MTb strains. 3) We are constructing a mycobacteriophage to detect and counterselect drug-resistant Mtb in the environment. 4) We are programming E. coli to follow MTb into human macrophages and saturate it with bacteriolytic enzymes. We want to vanquish tuberculosis and build a TB-free world.

Abstract: Plants as Plants: Natural Factories provides a green approach to the manufacturing of valuable chemicals and materials. Through synthetic biology, we are able to control the expression of genes that regulate the production of desired secondary metabolites. Via the manipulation of established metabolic pathways, we hope to produce vanillin and butanol. The prospect of being able to synthetically produce a biofuel provides vast possibilities for the scope of synthetic biology and green energy. Additionally through the manipulation of the cellulose synthase genes, we hope to increase the biomass of plants by a hybrid plant cell wall. As shown through these projects, the use of plants provides various green energy possibilities. However, due to the limited use of plants within synthetic biology there are various regulation issues. Thus we have additionally worked on characterizing a range of plant promoters as well as introducing the Cas9 crisper system into plants.

Abstract: Few researches have been done to regulate gene expression levels in genomic scale so far. This year we aim to combine two systems together in order to provide a universal and convenient tool which can be used to regulate different genomic genes simultaneously and independently in a quantitative way. Our project involves the newly developed gene regulating tool CRISPRi and three light-controlled expression systems induced by red, green, and blue light respectively. Simply by changing the regulating parts in CRISPRi system towards mRFP, luciferase, and three enzymes, we hope to prove our system can be used qualitatively, quantitatively and practically step by step. We have also designed a box and written a software as our experiment measurements. Simply by typing in several parameters, different gene expression levels can be controlled. This system can also be improved to predict the maximized producing efficiency after some simple tests in future.

Abstract: Communication is a dynamic requirement for life as we know it. We are using cellular and molecular messaging of different magnitudes to improve the broadcasting and reception of information. Starting on the atomic level, our BioWires project has created silver-incorporating DNA to act as nanowires, which could improve the cost and effectiveness of electronic products. Our CRISPR project is creating a system for DNA messages and resistances to be passed from cell to cell, in effect, creating transmissible probiotics and changing the way that cells communicate. We are also building a chromogenic biosensor to detect sucrose secretion that will be launched on a satellite (EuCROPIS) into low-Earth orbit. Finally, our De-Extinction project involves decoding messages from the past to better understand early life on Earth.

UCSF CRISPR page

Abstract: In microbial communities, bacterial populations are commonly controlled using indiscriminate, broad range antibiotics. There are few ways to target specific strains effectively without disrupting the entire microbiome and local environment. The goal of our project is to take advantage of a natural horizontal gene transfer mechanism in bacteria to precisely affect gene expression in selected strains. We combine bacterial conjugation with CRISPRi, an RNAi-like repression system developed from bacteria, to regulate gene expression in targeted strains within a complex microbial community. One possible application is to selectively repress pathogenic genes in a microbiome, leaving the community makeup unaffected. In addition, we use CRISPRi to lay the groundwork for transferring large circuits that enable complex functionality and decision-making in cells.

Abstract: Cas9 is an RNA-guided dsDNA nuclease utilized by bacteria immune system. The genetically engineered Cas9 has recently been shown to have the ability to repress or activate desired gene expression. In practical research and industrial application, we usually face the problem to express a gene at different levels, not only “on” or “off ”, so a more flexible regulation method is needed. To achieve multi-stage regulation of target genes, we further develop several dCas9 devices in which dCas9 alone or fused with omega subunit of RNAP is directed by various guide RNAs to different regions of designed double promoters. Therefore, promoters with disparate strength can be either activated or repressed respectively and multi-stage gene expression can be achieved. Also, based on such novel technology platform, we are developing diverse applications such as a guide RNA-mediated oscillator.
