dc.description.abstract | Immunoglobulin heavy chain (Igh) genes are assembled by sequential rearrangements of diversity (DH) and variable (VH) gene segments. Three critical constraints govern VH recombination. These include timing (VH recombination follows DH recombination), precision (VHs recombine only to DJH junctions) and allele specificity (VH recombination is restricted to DJH recombined alleles). We provide a model for these universal features of VH recombination. Analyses of DJH recombined alleles revealed that DJH junctions were selectively epigenetically marked, became nuclease sensitive and bound RAG proteins, thereby permitting DH-associated recombination signal sequences to initiate the second step of Igh gene assembly. We propose that VH recombination is precise because these changes did not extend to germline DH gene segments located 5′ of the DJH junction. | en |
