WebMar 21, 2024 ยท Rag1 plays a role in optic neuropathy as a proapoptotic candidate in p50-deficient mice. crystal structure of the mouse RAG1-RAG2 complex at 3.2 A resolution Integrated genetic approaches identify the molecular mechanisms of Sox4 in early B-cell development: intricate roles for RAG1/2 and CK1epsilon. WebMay 4, 2024 ยท The repeats-R1Nt interaction is constitutive, whereas the tBRCT-R1Ct interaction likely requires phosphorylation of the R1Ct motif of RAG1. As the C terminus of RAG1 has been implicated in inhibition of RAG activity, we propose a model in which phosphorylation of the R1Ct motif of RAG1 functions as a self-initiated regulatory signal.
WebIn vitro analyses of RAG function have relied on soluble, highly truncated "core" RAG proteins. ... Recent work has established that a dimer of RAG-1 and either one or two monomers of RAG-2 bind ... Web1. RAG1 or RAG2 deficiency causes a form of autosomal recessive T-B-NK+ SCID. It accounts for approximately 4% of all SCID cases. 2. The enormous diversity of specific immunoglobulins/B cell receptors and T cell receptors is generated through a process of V (D)J recombination.
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 tโฆ
WebThe RAG1 and RAG2 proteins initiate V(D)J recombination by introducing double-strand breaks at the border between a recombination signal sequence (RSS) and a coding segment.
