The protein encoded by this gene is involved in antibody and T-cell receptor V(D)J recombination. RAG-1 is involved in recognition of the DNA substrate, but stable binding and cleavage activity also requires RAG-2. The RAG-1/2 complex recognizes recombination signal sequences (RSSs) that flank the V, D and J regions in the genes that encode the heavy and light chains of antibodies and components of T-cell receptors. The complex binds to the RSSs and nicks the DNA. This leads t… WebFeb 27, 2024 · The recombination activating proteins (RAG1 and RAG2) initiate the process of V (D)J recombination, allowing for the formation of a diverse repertoire of T-cell receptors (TCRs) in T cells and immunoglobulins (Igs) in B cells. 10 This process is essential for the generation of polyclonal T and B cells with a broad antigen-recognition capacity. … WebFeb 10, 2024 · Mice deficient in recombination-activating genes 1 and 2 (RAG1 and RAG2) are considered a robust model to study the immune response in whole organisms.

WebOct 2, 2024 · RAG proteins are lymphoid-specific components of the complex of enzymes initiating the V (D)J recombination process ( Fugmann et al., 2000 ). They play a vital role in the rearrangement process of the variable (V), diversity (D), and joining (J) segments during the development of the B and T cell receptors (BCRs and TCRs, respectively). Web[1] During V (D)J recombination, the RAG complex (made up of RAG-1 and RAG-2 complexed with HMG1 or HMG2) binds to two recombination signal sequences (RSSs); the complex associates with each other, bringing the strands together, creating a loop which contains all the DNA between the two RSSs.

In the vertebrate immune system, each antibody is customized to attack one particular antigen (foreign proteins and carbohydrates) without attacking the body itself. The human genome has at most 30,000 genes, and yet it generates millions of different antibodies, which allows it to be able to respond to invasion from millions of different antigens. The immune system generates this diversity of antibodies by shuffling, cutting and recombining a few hundred genes (the VDJ gene… WebThe core of the RAG1 gene spans amino acids 384–1008, while the RAG2 core is on the N terminus, spanning amino acids 1–387 (Figure 4.7).At the N terminus, RAG1 protein contains multiple zinc-binding motifs defined by a C 2 H 2 zinc finger (ZFA) and a C 3 HC 4 zinc-binding motif, which is critically involved in the interaction between a group of enzymes …
