V(D)J recombination: RAG proteins, repair factors, and regulationMartin Gellert
Laboratory of Molecular Biology, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, 9000 Rockville Pike, Bethesda, Maryland 20892 0540, USA
Annu Rev Biochem 71:101-32. 2002..This transposition helps to explain the mechanism of RAG action and supports earlier proposals that V(D)J recombination evolved from an ancient mobile DNA element...
Ordered assembly of the V(D)J synaptic complex ensures accurate recombinationJessica M Jones
Laboratory of Molecular Biology, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Building 5 Room 241, Bethesda, MD 20892, USA
EMBO J 21:4162-71. 2002..Additional cellular factors such as chromatin may ensure that RAG1/2 first assembles on a 12 RSS, and then a free 23 RSS enters to activate cleavage...
Autoinhibition of DNA cleavage mediated by RAG1 and RAG2 is overcome by an epigenetic signal in V(D)J recombinationGabrielle J Grundy
Laboratory of Molecular Biology, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Bethesda, MD 20892, USA
Proc Natl Acad Sci U S A 107:22487-92. 2010..Thus a negative regulatory function of the noncore regions of RAG1/2 limits the RAG endonuclease activity in the absence of an activating methylated histone tail bound to the complex...
Initial stages of V(D)J recombination: the organization of RAG1/2 and RSS DNA in the postcleavage complexGabrielle J Grundy
Laboratory of Molecular Biology, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Bethesda, MD 20892, USA
Mol Cell 35:217-27. 2009..These first images of the V(D)J recombinase in its postcleavage state provide a framework for modeling RAG domains and their interactions with DNA...
Mechanism of mismatch recognition revealed by human MutSβ bound to unpaired DNA loopsShikha Gupta
Laboratory of Molecular Biology, National Institute of Diabetes and Digestive and Kidney Diseases, US National Institutes of Health, Bethesda, Maryland, USA
Nat Struct Mol Biol 19:72-8. 2012..The C-terminal dimerization domains form an integral part of the MutS structure and coordinate asymmetrical ATP hydrolysis by Msh2 and Msh3 with mismatch binding to signal for repair...
Inverse transposition by the RAG1 and RAG2 proteins: role reversal of donor and target DNAI-Hung Shih
Laboratory of Molecular Biology, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Building 5, Room 241, Bethesda, MD 20892, USA
EMBO J 21:6625-33. 2002..This aberrant activity provides another possible mechanism for some chromosomal translocations present in lymphoid tumors...
Autoubiquitylation of the V(D)J recombinase protein RAG1Jessica M Jones
Laboratory of Molecular Biology, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Building 5 Room 241, Bethesda, MD 20892, USA
Proc Natl Acad Sci U S A 100:15446-51. 2003..Disruption of the RING finger and certain RAG1 N-terminal truncations are associated with immunodeficiency in human patients, suggesting that RAG1's ubiquitin ligase is required for its biological role in lymphocyte development...
Requirements for DNA hairpin formation by RAG1/2Gabrielle J Grundy
Laboratory of Molecular Biology, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Building 5, Room 241, Bethesda, MD 20892, USA
Proc Natl Acad Sci U S A 104:3078-83. 2007..A W956A mutation in RAG1 had an inhibitory effect on both nicking and hairpin stages that could be rescued by abasic substrates. W956 is therefore a likely candidate for interacting with this base during hairpin formation...
An activation-induced cytidine deaminase-independent mechanism of secondary VH gene rearrangement in preimmune human B cellsNancy S Longo
Autoimmunity Branch, National Institute of Arthritis and Musculoskeletal and Skin Diseases, National Institute of Diabetes andDigestive and Kidney Diseases, National Institutes of Health, Bethesda, MD 20892 1560, USA
J Immunol 181:7825-34. 2008..The data suggest that V(H)4 replacement in preimmune human B cells is mediated by an AICDA-independent mechanism resulting from inefficient but selective RAG activity...
Effect of HIV integrase inhibitors on the RAG1/2 recombinaseMeni Melek
Laboratory of Molecular Biology, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Building 5, Room 241, Bethesda, MD 20892, USA
Proc Natl Acad Sci U S A 99:134-7. 2002..These results further underscore the similarities between RAG1/2 and integrase and suggest that certain integrase inhibitors may have the potential to interfere with aspects of B and T cell development...
Tetramerization and DNA ligase IV interaction of the DNA double-strand break repair protein XRCC4 are mutually exclusiveMauro Modesti
Department of Cell Biology and Genetics, Erasmus Medical Center, P O Box 1738, 3000 DR, Rotterdam, The Netherlands
J Mol Biol 334:215-28. 2003..We propose that the putative function of the XRCC4 tetramer is distinct from its DNA ligase IV-associated function...
