MegaGate: A toxin-less gateway molecular cloning tool.

ABSTRACT: Gateway cloning employs the use of the ccdb toxin and has low colony numbers, making it difficult to apply at scale to clone libraries of cDNA vectors. In this protocol, we describe MegaGate, a toxin-less Gateway technology capable of robust cDNA library cloning that is efficient, cheap, and scalable. MegaGate eliminates the ccdb toxin used in Gateway recombinase cloning and instead utilizes meganuclease-mediated digestion to eliminate background vectors during cloning and is 99.8% efficient with high colony numbers. For complete details on the use and execution of this protocol, please refer to Kramme et al. (2021).

A Gateway MultiSite recombination cloning toolkit.

Project description:The generation of DNA constructs is often a rate-limiting step in conducting biological experiments. Recombination cloning of single DNA fragments using the Gateway system provided an advance over traditional restriction enzyme cloning due to increases in efficiency and reliability. Here we introduce a series of entry clones and a destination vector for use in two, three, and four fragment Gateway MultiSite recombination cloning whose advantages include increased flexibility and versatility. In contrast to Gateway single-fragment cloning approaches where variations are typically incorporated into model system-specific destination vectors, our Gateway MultiSite cloning strategy incorporates variations in easily generated entry clones that are model system-independent. In particular, we present entry clones containing insertions of GAL4, QF, UAS, QUAS, eGFP, and mCherry, among others, and demonstrate their in vivo functionality in Drosophila by using them to generate expression clones including GAL4 and QF drivers for various trp ion channel family members, UAS and QUAS excitatory and inhibitory light-gated ion channels, and QUAS red and green fluorescent synaptic vesicle markers. We thus establish a starter toolkit of modular Gateway MultiSite entry clones potentially adaptable to any model system. An inventory of entry clones and destination vectors for Gateway MultiSite cloning has also been established (www.gatewaymultisite.org).

Expansion of the gateway multisite recombination cloning toolkit.

Project description:Precise manipulation of transgene expression in genetic model organisms has led to advances in understanding fundamental mechanisms of development, physiology, and genetic disease. Transgene construction is, however, a precondition of transgene expression, and often limits the rate of experimental progress. Here we report an expansion of the modular Gateway MultiSite recombination-cloning platform for high efficiency transgene assembly. The expansion includes two additional destination vectors and entry clones for the LexA binary transcription system, among others. These new tools enhance the expression levels possible with Gateway MultiSite generated transgenes and make possible the generation of LexA drivers and reporters with Gateway MultiSite cloning. In vivo data from transgenic Drosophila functionally validating each novel component are presented and include neuronal LexA drivers, LexAop2 red and green fluorescent synaptic vesicle reporters, TDC2 and TRH LexA, GAL4, and QF drivers, and LexAop2, UAS, and QUAS channelrhodopsin2 T159C reporters.

Gateway cloning is compatible with protein secretion from Pichia pastoris.

Project description:Secretion of a recombinant protein from the yeast Pichia pastoris requires the presence of a signal peptide at the amino terminus. Maintaining the full amino acid sequence of the signal peptide is thought to be important for proper signal processing and protein secretion. We show that at least for one protein, a synthetic human interferon, the presence of a Gateway recombination site within the signal peptide is fully compatible with high levels of protein secretion. The amino termini of the secreted interferon proteins cloned with Gateway and cloned with restriction enzymes and ligase are identical, and the proteins were highly active in biological assays. Compatibility with Gateway cloning simplifies construction of plasmids directing secretion of recombinant proteins from P. pastoris.

A modified Gateway cloning strategy for overexpressing tagged proteins in plants.

Project description:BACKGROUND:Recent developments, including the sequencing of a number of plant genomes, have greatly increased the amount of data available to scientists and has enabled high throughput investigations where many genes are investigated simultaneously. To perform these studies, recombinational cloning methods such as the Gateway system have been adapted to plant transformation vectors to facilitate the creation of overexpression, tagging and silencing vectors on a large scale. RESULTS:Here we present a hybrid cloning strategy which combines advantages of both recombinational and traditional cloning and which is particularly amenable to low-to-medium throughput investigations of protein function using techniques of molecular biochemistry and cell biology. The system consists of a series of twelve Gateway Entry cassettes into which a gene of interest can be inserted using traditional cloning methods to generate either N- or C-terminal fusions to epitope tags and fluorescent proteins. The resulting gene-tag fusions can then be recombined into Gateway-based Destination vectors, thus providing a wide choice of resistance marker, promoter and expression system. The advantage of this modified Gateway cloning strategy is that the entire open reading frame encoding the tagged protein of interest is contained within the Entry vectors so that after recombination no additional linker sequences are added between the tag and the protein that could interfere with protein function and expression. We demonstrate the utility of this system for both transient and stable Agrobacterium-mediated plant transformations. CONCLUSION:This modified Gateway cloning strategy is complementary to more conventional Gateway-based systems because it expands the choice of tags and higher orders of combinations, and permits more control over the linker sequence lying between a protein of interest and an epitope tag, which can be particularly important for studies of protein function.

Gateway cloning vectors for the LexA-based binary expression system in Drosophila.

Project description:Studies on the formation of connections in the developing nervous system are greatly aided by methods that permit the differential visualisation and manipulation of pre- and postsynaptic partner neurons. This has been facilitated by the advent of the LexA-based, GAL4/UAS-independent, binary expression system. On the molecular side, the introduction of DNA sequences into expression vectors has been simplified by the Invitrogen Gateway cloning technology. We have developed cloning vectors that combine the Gateway cloning technology with the LexA-based genetic expression system. These vectors facilitate the creation of driver and reporter constructs for the generation of Drosophila transgenic lines for the new LexA-based binary transcriptional system. We further report a new LexA::GAD sensory neuron driver and a red fluorescent membrane targeted lexAop reporter designed to complement the existing GFP-based lexAop reporter. Using these transgenic lines we have been able to differentially label motor and sensory neuron projections in the ventral nerve cord of Drosophila larvae.

Overlap extension cloning of PCR products into a Gateway-compatible plasmid vector.

Project description:A PCR cloning method that combines a dual selection pGATE-1 plasmid vector and an improved overlap extension cloning was developed. This efficient and cost-effective method allows for the introduction of DNA fragments into the Gateway cloning pipeline. The cloning efficiency is facilitated by a dual selection that includes the ccdB gene and gentamicin resistance. For users of the Gateway cloning system, substantial cost saving comes from eliminating BP recombination and ligation reactions to introduce DNA fragments into pDONR or pENTR vectors. Beyond the Gateway technology, this recombination-based cloning system can be used to efficiently clone PCR amplicons by adding 24-base pair adaptor sequences that are utilized by bacterial homologous recombination mechanism.

Development of the Gateway system for cloning and expressing genes in Entamoeba histolytica.

Project description:The early branching eukaryote Entamoeba histolytica is a human parasite that is the etiologic agent of amebic dysentery and liver abscess. The sequencing of the E. histolytica genome combined with the development of an E. histolytica microarray has resulted in the identification of several distinct gene expression profiles associated with virulence. The function of many modulated transcripts is unknown and their role in pathogenicity is unclear. They however represent a pool of potential virulence factors that could be targets for the development of novel therapeutics. Efficient tools and methods to characterize these novel virulence-associated genes and proteins would be beneficial. Here we report the use of the Gateway((R)) cloning system to generate the E. histolytica expression vector pAH-DEST. To test the usefulness of this system, the vector was used to construct a plasmid containing a recombinant version of the locus EHI_144490, which encoded a protein of unknown function. The recombinant gene was expressed and the recombinant protein, which was strep-myc-tagged, showed a cytoplasmic localization in transfected trophozoites. This expression vector with the Gateway((R)) system should facilitate investigation into the functions of novel proteins in E. histolytica.

A Split-GFP Gateway Cloning System for Topology Analyses of Membrane Proteins in Plants.

Project description:To understand the function of membrane proteins, it is imperative to know their topology. For such studies, a split green fluorescent protein (GFP) method is useful. GFP is barrel-shaped, consisting of 11 β-sheets. When the first ten β-sheets (GFP1-10) and the 11th β-sheet (GFP11) are expressed from separate genes they will self-assembly and reconstitute a fluorescent GFP protein. However, this will only occur when the two domains co-localize in the same cellular compartment. We have developed an easy-to-use Gateway vector set for determining on which side of the membrane the N- and C-termini are located. Two vectors were designed for making N- and C-terminal fusions between the membrane proteins-of-interest and GFP11, while another three plasmids were designed to express GFP1-10 in either the cytosol, the endoplasmic reticulum (ER) lumen or the apoplast. We tested functionality of the system by applying the vector set for the transmembrane domain, CNXTM, of the ER membrane protein, calnexin, after transient expression in Nicotiana benthamiana leaves. We observed GFP signal from the ER when we reciprocally co-expressed GFP11-CNXTM with GFP1-10-HDEL and CNXTM-GFP with cytosolic GFP1-10. The opposite combinations did not result in GFP signal emission. This test using the calnexin ER-membrane domain demonstrated its C-terminus to be in the cytosol and its N-terminus in the ER lumen. This result confirmed the known topology of calnexin, and we therefore consider this split-GFP system highly useful for ER membrane topology studies. Furthermore, the vector set provided is useful for detecting the topology of proteins on other membranes in the cell, which we confirmed for a plasma membrane syntaxin. The set of five Ti-plasmids are easily and efficiently used for Gateway cloning and transient transformation of N. benthamiana leaves.

Revolutionizing Molecular cloning: Introducing FastCloneAssist, a Streamlined Python tool for optimizing primer design in restriction & ligation-independent PCR cloning.

Project description:FastCloning, a paradigm shift in PCR cloning, has streamlined the process by eliminating laborious, multi-step traditional methods. This innovative technique, pioneered by Li et al. (2011), utilizes overlapping PCR primers and DpnI digestion for seamless integration of insert DNA into any desired vector position, regardless of restriction sites. This versatility makes FastCloning ideal for constructing fusion proteins, chimeric cDNAs, and manipulating genes with unparalleled ease. However, efficient primer design remains a critical hurdle, particularly for newcomers, as errors can lead to failed cloning attempts. To address this bottleneck, we present FastCloneAssist, a user-friendly Python program that automates FastCloning primer design with minimal user input. Users simply provide vector and insert sequences, along with the desired melting temperature (Tm), and FastCloneAssist provides best primer pairs after calculating optimal primer parameters for efficient PCR amplification and seamless DNA integration using established bioinformatics libraries. This open-source, freely available tool simplifies and accelerates cloning, making this powerful technique accessible to researchers of all levels and expediting scientific discovery.
