During the development of B Cells in the bone marrow, a process called VDJ Recombination occurs. During this process, developing B Cells have their exons rem

The repertoires are simulated by in-silico VDJ recombination. Each repertoire will consist of a user-predefined number of fully annotated immune receptor sequences. The user can generate pdfs summarizing the major features of the generated repertoire that includes: VDJ usage, positional amino acid frequency and gapped-k-mer occurrence.

The DNA sequence requirements for V(D)J recombination consist of highly conserved heptamer and nonamer DNA motifs separated by a spacer of 12 or 23 base pairs (12 RSS and 23 RSS, where RSS is recombination signal sequence). VDJ recombination, also known as antigen receptor gene rearrangement or antigen-independent diversification, is a diversity generating assembly process affecting the variable domain of immunoglobulin and TCR genes. V(D)J recombination undergoes regulation at multiple levels, including the regulation of RAG1/2 activity, subnuclear reposition, spatial conformation of chromatin, and Vκ recombination, and has some specific regulation mechanisms. VDJ recombinase refers to a collection of enzymes some of which are lymphocyte specific, and some that are expressed in many cell types.

These BCR sequences are created in “draft” form by VDJ recombination, which randomly selects and deletes from the ends of V, D, and J genes, then joins them together with additional random nucleotides. It is also intended to provide a method to enable a high-throughput detection of VDJ recombination events by generating sequencer-ready libraries specific to the CDR3-specific antigen binding regions of B and T cells.

Therefore, it is of interest to determine the effect of these mutations on the accumulation of hairpin coding ends in vivo. Oct 13, 2003 An Evolutionary Model of V(D)J Recombination. From the discovery of the RAG genes on, investigators have suspected that V(D)J recombination Apr 23, 2006 Through V(D)J recombination, the variable region of antigen receptor genes is assembled from component V, D, and J gene segments.

The key enzymes involved are recombination activating genes 1 and 2 (RAG), terminal deoxynucleotidyl transferase (TdT), and Artemis nuclease, a member of the ubiquitous non-homologous end joining (NHEJ) pathway for DNA repair. [4] V(D)J recombination is the process by which immunoglobulins are assembled for expression during B-lymphocyte development (Early et al., 1980; Jung et al., 2006). This process has two major outcomes, the generation of a functional diversified V gene and the expression of a single type of receptor per B-lymphocyte.

The initial steps of VDJ recombination are carried out by critical lymphocyte specific enzymes, called recombination activating gene-1 and -2 (RAG1 and RAG2). These enzymes associate with each other to The first step of V(D)J recombination, specific cleavage at the recombination signal sequence (RSS), can be carried out by the recombination activating proteins RAG1 and RAG2. In vivo , the cleaved coding and signal ends must be rejoined to generate functional antigen receptors and maintain chromosomal integrity. We have investigated signal joint formation using deletion and inversion The second phase of V(D)J recombination, end processing and end joining, involves RAG1 and 2 as well as the DNA-repair proteins of the nonhomologous end-joining pathway.
