Rag1/2 function
WebFrom this conceptual starting point, we found that human RAG1 formed scattered aggregates in the entire nucleus of cells, and RAG2 abolished RAG1 aggregation to initiate V (D)J recombination. Our findings provide an additional explanation of how RAG2 restricts RAG1 to function in only the G1 phase of the cell cycle. WebTo the Editor. There is a great diversity of RAG1 and RAG2-dependent primary immunodeficiencies (PID) ranging from severe combined immunodeficiency (SCID) to various late-onset combined immunodeficiencies, as complete lack of RAG activity leads to absence of mature B and T cells (T- B- SCID), whereas hypomorphic RAG mutations allow …

WebMar 21, 2024 · The complex RAG1/2 binds one copy each of 12 recombination signal sequence and 23 recombination signal sequence DNA. SATB1 binds to the ASE and Rag promoters, facilitating inclusion of Rag2 in the chromatin hub and the loading of RNA polymerase II to both the Rag1 and Rag2 promoters. WebRAG1 and RAG2 are two proteins necessary for immunoglobulin and T-cell receptor gene recombination. RAG stands for recombination-activating gene. RAG1 and RAG2 work closely together in receptor gene recombination. Therefore, immunologists often refer to the two proteins together as RAG protein.
