Summary
Researchers developed a new Vika/vox site-specific recombinase (SSR) system for precise DNA manipulation. This novel tool offers high specificity and safety, expanding options for complex genome engineering applications.
Area of Science:
- Molecular Biology
- Genetics
- Biotechnology
Background:
- Site-specific recombinases (SSRs) are crucial for DNA manipulation in various research fields.
- Increasing complexity in genetic studies necessitates novel and efficient SSR systems.
- Existing SSRs have limitations, driving the need for new tools.
Purpose of the Study:
- To introduce and characterize a novel site-specific recombination system, Vika/vox.
- To evaluate the specificity, efficiency, and safety of the Vika/vox system.
- To compare Vika/vox with existing SSR systems for application guidance.
Main Methods:
- Isolation and characterization of the Vika recombinase from a bacteriophage.
- Demonstration of Vika's specific DNA recombination activity on the vox target site.
- Comparative analysis of Vika/vox recombination efficiency against other SSR systems.
- Assessment of Vika's cytotoxicity in mammalian cell lines.
Main Results:
- Vika/vox functions as a novel site-specific recombination system.
- Vika exhibits high specificity, recombining only the vox target site.
- Vika/vox demonstrates efficient recombination activity comparable to existing SSRs.
- Vika expression showed no cytotoxicity in mammalian cells.
Conclusions:
- Vika/vox is a powerful and safe new tool for genome engineering.
- The system can be used independently or combined with other SSRs.
- Vika/vox expands the 'genetic toolbox' for complex genetic studies and applications.

02:53Conservative Site-specific Recombination and Phase Variation
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.

02:31Homologous Recombination
The basic reaction of homologous recombination (HR) involves two chromatids that contain DNA sequences sharing a significant stretch of identity. One of these sequences uses a strand from another as a template to synthesize DNA in an enzyme-catalyzed reaction. The final product is a novel amalgamation of the two substrates. To ensure an accurate recombination of sequences, HR is restricted to the S and G2 phases of the cell cycle. At these stages, the DNA has been replicated already and the...

02:32Exon Recombination
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.

01:02Long-patch Base Excision Repair
Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
00:57Viral Recombination
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
