Genetic Code Expansion in Zebrafish Embryos and Its Application to Optical Control of Cell Signaling.

ABSTRACT: Site-specific incorporation of unnatural amino acids into proteins provides a powerful tool to study protein function. Here we report genetic code expansion in zebrafish embryos and its application to the optogenetic control of cell signaling. We genetically encoded four unnatural amino acids with a diverse set of functional groups, which included a photocaged lysine that was applied to the light-activation of luciferase and kinase activity. This approach enables versatile manipulation of protein function in live zebrafish embryos, a transparent and commonly used model organism to study embryonic development.

Optical Control of DNA Helicase Function through Genetic Code Expansion.

Project description:Nucleotide excision repair (NER) is a general DNA repair mechanism that is capable of removing a wide variety of DNA lesions induced by physical or chemical insults. UvrD, a member of the helicase SF1 superfamily, plays an essential role in bacterial NER by unwinding the duplex DNA in the 3' to 5' direction to displace the lesion-containing strand. In order to achieve conditional control over NER, we generated a light-activated DNA helicase. This was achieved through a site-specific incorporation of a genetically encoded hydroxycoumarin lysine at a crucial position in the ATP-binding pocket of UvrD. The resulting caged enzyme was completely inactive in several functional assays. Moreover, enzymatic activity of the optically triggered UvrD was comparable to that of the wild-type protein, thus demonstrating excellent OFF to ON switching of the helicase. The developed approach provides optical control of NER, thereby laying a foundation for the regulation of ATP-dependent helicase functions in higher organisms. In addition, this methodology is applicable to the light-activation of a wide range of ATPases.

Precise optical control of gene expression in <i>C elegans</i> using improved genetic code expansion and Cre recombinase.

Project description:Synthetic strategies for optically controlling gene expression may enable the precise spatiotemporal control of genes in any combination of cells that cannot be targeted with specific promoters. We develop an improved genetic code expansion system in Caenorhabditis elegans and use it to create a photoactivatable Cre recombinase. We laser-activate Cre in single neurons within a bilaterally symmetric pair to selectively switch on expression of a loxP-controlled optogenetic channel in the targeted neuron. We use the system to dissect, in freely moving animals, the individual contributions of the mechanosensory neurons PLML/PLMR to the C. elegans touch response circuit, revealing distinct and synergistic roles for these neurons. We thus demonstrate how genetic code expansion and optical targeting can be combined to break the symmetry of neuron pairs and dissect behavioural outputs of individual neurons that cannot be genetically targeted.

Genetic Code Expansion System for Tight Control of Gene Expression in Bombyx mori Cell Lines.

Project description:Inducible gene expression systems are important tools for studying gene function and to control protein synthesis. With the completion of the detailed map of the silkworm (Bombyx mori) genome, the study of Bombyx mori has entered the post-genome era. While the functions of many genes have been described in detail, many coding genes remain unidentified. Except for the available tetracycline induction system, there is currently a dearth of other effective induction systems for B. mori. A genetic code expansion system can be used for protein labeling and to regulate gene expression. Here, we have established a genetic code expansion system for B. mori based on the well-researched tRNAPyl/PylRS pair from Methanosarcina mazei. We used H-Lys(Boc)-OH, which is a lysine derivative to efficiently and tightly control the expression of the reporter gene DsRed[TAG]EGFP (D[TAG]G), which encoded a H-Lys(Boc)-OH-bearing protein fused with DsRed and EGFP (here regarded as D[Boc]G) in B. mori cell lines BmE and BmNs. In D[TAG]G, the amber stop codon is recognized as the orthogonal tRNAPyl. Successful application of genetic code expansion system in silkworm cell lines will support the research into the function of silkworm genes and paves the way for the identification of new genes and protein markers in silkworm.

Genetic Code Expansion in Animals.

Project description:Expanding the genetic code to enable the incorporation of unnatural amino acids into proteins in biological systems provides a powerful tool for studying protein structure and function. While this technology has been mostly developed and applied in bacterial and mammalian cells, it recently expanded into animals, including worms, fruit flies, zebrafish, and mice. In this review, we highlight recent advances toward the methodology development of genetic code expansion in animal model organisms. We further illustrate the applications, including proteomic labeling in fruit flies and mice and optical control of protein function in mice and zebrafish. We summarize the challenges of unnatural amino acid mutagenesis in animals and the promising directions toward broad application of this emerging technology.

Genetically Encoded Aminocoumarin Lysine for Optical Control of Protein-Nucleotide Interactions in Zebrafish Embryos.

Project description:The strategic placement of unnatural amino acids into the active site of kinases and phosphatases has allowed for the generation of photocaged signaling proteins that offer spatiotemporal control over activation of these pathways through precise light exposure. However, deploying this technology to study cell signaling in the context of embryo development has been limited. The promise of optical control is especially useful in the early stages of an embryo where development is driven by tightly orchestrated signaling events. Here, we demonstrate light-induced activation of Protein Kinase A and a RASopathy mutant of NRAS in the zebrafish embryo using a new light-activated amino acid. We applied this approach to gain insight into the roles of these proteins in gastrulation and heart development and forge a path for further investigation of RASopathy mutant proteins in animals.

Switchable genome editing via genetic code expansion.

Project description:Multiple applications of genome editing by CRISPR-Cas9 necessitate stringent regulation and Cas9 variants have accordingly been generated whose activity responds to small ligands, temperature or light. However, these approaches are often impracticable, for example in clinical therapeutic genome editing in situ or gene drives in which environmentally-compatible control is paramount. With this in mind, we have developed heritable Cas9-mediated mammalian genome editing that is acutely controlled by the cheap lysine derivative, Lys(Boc) (BOC). Genetic code expansion permitted non-physiological BOC incorporation such that Cas9 (Cas9BOC) was expressed in a full-length, active form in cultured somatic cells only after BOC exposure. Stringently BOC-dependent, heritable editing of transgenic and native genomic loci occurred when Cas9BOC was expressed at the onset of mouse embryonic development from cRNA or Cas9BOC transgenic females. The tightly controlled Cas9 editing system reported here promises to have broad applications and is a first step towards purposed, spatiotemporal gene drive regulation over large geographical ranges.

Inducible Genetic Code Expansion in Eukaryotes.

Project description:Genetic code expansion (GCE) is a versatile tool to site-specifically incorporate a noncanonical amino acid (ncAA) into a protein, for example, to perform fluorescent labeling inside living cells. To this end, an orthogonal aminoacyl-tRNA-synthetase/tRNA (RS/tRNA) pair is used to insert the ncAA in response to an amber stop codon in the protein of interest. One of the drawbacks of this system is that, in order to achieve maximum efficiency, high levels of the orthogonal tRNA are required, and this could interfere with host cell functionality. To minimize the adverse effects on the host, we have developed an inducible GCE system that enables us to switch on tRNA or RS expression when needed. In particular, we tested different promotors in the context of the T-REx or Tet-On systems to control expression of the desired orthogonal tRNA and/or RS. We discuss our result with respect to the control of GCE components as well as efficiency. We found that only the T-REx system enables simultaneous control of tRNA and RS expression.

Genetic code expansion in stable cell lines enables encoded chromatin modification.

Project description:Genetically encoded unnatural amino acids provide powerful strategies for modulating the molecular functions of proteins in mammalian cells. However, this approach has not been coupled to genome-wide measurements, because efficient incorporation of unnatural amino acids is limited to transient expression settings that lead to very heterogeneous expression. We demonstrate that stable integration of the Methanosarcina mazei pyrrolysyl-tRNA synthetase (PylRS)/tRNA(Pyl)CUA pair (and its derivatives) into the mammalian genome enables efficient, homogeneous incorporation of unnatural amino acids into target proteins in diverse mammalian cells, and we reveal the distinct transcriptional responses of embryonic stem cells and mouse embryonic fibroblasts to amber codon suppression. Genetically encoding N-?-acetyl-lysine in place of six lysine residues in histone H3 enables deposition of pre-acetylated histones into cellular chromatin, via a pathway that is orthogonal to enzymatic modification. After synthetically encoding lysine-acetylation at natural modification sites, we determined the consequences of acetylation at specific amino acids in histones for gene expression.
