Summary
V(D)J recombination assembles immune genes using RAG1 and RAG2 proteins. This process is vital for lymphocyte development and adaptive immunity, involving complex DNA interactions and evolutionary considerations.
Area of Science:
- Immunology
- Molecular Biology
- Biochemistry
Background:
- Adaptive immunity relies on diverse T cell receptors and immunoglobulins.
- These proteins are generated through V(D)J recombination, a DNA rearrangement process.
- The RAG1 and RAG2 proteins are key mediators of V(D)J recombination.
Purpose of the Study:
- To explore the biochemical mechanisms of V(D)J recombination.
- To understand the DNA transactions and protein interactions involved.
- To examine the evolutionary origins of RAG proteins and V(D)J recombination.
Main Methods:
- Biochemical analysis of V(D)J recombination.
- Focus on DNA cleavage and protein-DNA interactions.
- Comparative evolutionary analysis of RAG proteins.
Main Results:
- Detailed examination of the biochemical steps in V(D)J recombination.

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...
02:08Gene Conversion
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...
02:13Overview of Transposition and Recombination
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...
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.
The recognition sites for Cre recombinase called LoxP...

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.
