What does VDJ stand for Immunology?
VDJ stands for variability, diversity, and joining, respectively, and VDJ rearrangement has 4 key characteristics that help ensure that each antigen receptor is unique.
What is meant by the 12 23 rule?
The 12/23 rule, which is mediated at the level of RAG-1/2 recognition and cutting4,5, specifies that V(D)J recombination occurs only between a gene segment flanked by a 12-RSS and one flanked by a 23-RSS1.
What is Vdj recombination do?
VDJ recombination is the process by which T cells and B cells randomly assemble different gene segments – known as variable (V), diversity (D) and joining (J) genes – in order to generate unique receptors (known as antigen receptors) that can collectively recognize many different types of molecule.
What is produced by V d J recombination?
V(D)J recombination is the mechanism of somatic recombination that occurs only in developing lymphocytes during the early stages of T and B cell maturation. It results in the highly diverse repertoire of antibodies/immunoglobulins and T cell receptors (TCRs) found in B cells and T cells, respectively.

What is RSS immunology?
RSS (Really Simple Syndication) is a web feed XML format that contains either a summary of content from an associated web site or the full text. The Journal of Immunology offers RSS feeds of current and recent citation information and abstracts.
What is RSS in immunology?
RSSs flank all gene segments of the antigen receptor loci and designate them for use by the RAGs. Each RSS is composed of a well-conserved heptamer and nonamer with a less well-conserved spacer between these elements (Figure 3). The recombination signal sequence (RSS). …
What is a coding joint?
During recombination, coding ends and signal ends are. generated by recombinase-mediated cleavage at the cross- over sites. The two coding ends are joined to form what is. termed a coding joint, andthe two signal ends are joined to.
What is the meaning of Vdj?
Is Vdj recombination post translational?
V(D)J recombination is initiated by the lymphoid-specific proteins, RAG1 and RAG2. The posttranslational modification of RAG2 in a cell cycle–dependent manner also links RAG activity to the cell cycle.
Which pathway joins the DNA ends created by RAG1 RAG2 cleavage during Vdj recombination?
The frequent presence of such “microscopic” junctional alterations at coding joints provides a powerful mechanism for amplifying the diversity of antigen binding sites in T cell receptor and immunoglobulin molecules. RAG-generated DNA ends are normally joined by cNHEJ (reviewed by (51).
