Diversity in immunoglobulin antigen receptors is generated in part by V(D)J recombination. In this process, different combinations of gene elements are joined in various configurations. Products of V(D)J recombination are coding joints, signal joints, and hybrid junctions, which are generated by deletion or inversion. To determine their role in the generation of diversity, we have examined two sorts of recombination products, coding joints and hybrid junctions, that have formed by inversion at the mouse immunoglobulin heavy-chain locus. We developed a PCR assay for quantification and characterization of inverted rearrangements of DH and JH gene elements. In primary cells from adult mice, inverted DJH rearrangements are detectable but they are rare. There were approximately 1,100 to 2,200 inverted DJH coding joints and inverted DJH hybrid junctions in the marrow of one adult mouse femur. On day 16 of gestation, inverted DJH rearrangements are more abundant. There are approximately 20,000 inverted DJH coding joints and inverted DJH hybrid junctions per day 16 fetal liver. In fetal liver cells, the number of inverted DJH rearrangements remains relatively constant from day 14 to day 16 of gestation. Inverted DJH rearrangements to JH4, the most 3' JH element, are more frequently detected than inverted DJH rearrangements to other JH elements. We compare the frequencies of inverted DJH rearrangements to previously determined frequencies of uninverted DJH rearrangements (DJH rearrangements formed by deletion). We suggest that inverted DJH rearrangements are influenced by V(D)J recombination mechanistic constraints and cellular selection.
