Alternatively, students could model VDJ recombination with pipe cleaners and then perform this activity to deduce the polypeptide consequences of the recombination. This described activity concentrates on the gene product, as contrasted with the techniques described in ( 8 , 9 ) that are constructed around the process ( 8 ) and structural outcome ( 9 ) of VDJ recombination.

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. Although the mechanism of V (D)J recombination has been extensively studied in developing lymphocytes of mice and humans, the presence of the enzymes (RAG1/RAG2 and terminal deoxynucleotidyl transferase) that mediate the process and the conservation of the RSSs (RSS pairs consisting of a 12-bp spacer and a 23-bp spacer) suggest that this process is conserved in all tetrapod species. VDJ recombinase refers to a collection of enzymes some of which are lymphocyte specific, and some that are expressed in many cell types. The initial steps of VDJ recombination are carried out by critical lymphocyte specific enzymes, called recombination activating gene -1 and -2 (RAG1 and RAG2).

Activated mature B cells also possess two other remarkable, RAG-independent phenomena of manipulating their own DNA: so-called class-switch recombination (AKA isotype switching) and somatic hypermutation (AKA affinity maturation). REC BCD ENZYME The recBCD enzyme (exonuclease V) ofE. coli is a complex, multifunctional protein that catalyzes the hydrolysis of both linear duplex and single-stranded DNA, coupled to the hydrolysis of ATP (28-31). It is also an ATP-stimulated endonuclease that acts specifically on single-stranded DNA. 2003-10-13 · V(D)J recombination is absolutely crucial for the adaptive immune response.

Several lymphoid-specific factors are known to be involved in V (D)J recombination. These include terminal deoxynucleotidyltransferase ( 2, 3, 4) and the recombination activating proteins RAG1 and RAG2 ( 5, 6, 7 ).

The genes that encode immunoglobulin and T cell receptor proteins are assembled from component gene segments in a reaction known as V (D)J recombination. The reaction, and its crucial mediators

VDJ recombinase refers to a collection of enzymes some of which are lymphocyte specific, and some that are expressed in many cell types. 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 recognize the RSS sequences and induce DNA cleavage at the RSS sequences. 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. This combinatorial diversification uses the diversity of the different V, D, and J gene segments present in the germline to generate one set of diverse combinations.

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. 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.

The formation of heterochromatin is known to influence RAG2, catalyzing the VDJ recombination. Moreover, SUV39H1 has a role in the methylation of RAG2, which changes RAG2 subnuclear localization, and might regulate the chromatin binding of RAG2. 37
