Rate of replication of the murine immunoglobulin heavy-chain locus: evidence that the region is part of a single replicon
Results provide evidence that in murine non-B cells the IgCH, J, and D loci are part of a single replicon, similar to the rate measured for mammalian replicons by autoradiography and electron microscopy.
Class switch recombination of the chicken IgH chain genes: implications for the primordial switch region repeats.
A primordial palindromic sequence from which the prevalent switch repeat motifs of mammals, chickens and amphibians may have diverged is presented.
Nucleotide sequences of all the γ gene loci of murine immunoglobulin heavy chains
The nucleotide sequence of the entire region that encodes the γ chains of mouse immunoglobulin was determined and Duplication of a primordial γ2 gene seems likely to have occurred by homologous recombination that involved the 3′CR sequences.
Rat immunoglobulin E heavy chain locus.
Unusual sequences in the murine immunoglobulin μ–δ heavy-chain region
The complete sequence as well as the sequence of the introns of the Cδ gene are presented and it is determined that the 3′ deletion end point of an IgD-producing myeloma is determined and no sequences reminiscent of switch sites nearby are found.
Physical Mapping of the Bovine Immunoglobulin Heavy Chain Constant Region Gene Locus*
Bovine antibodies have recently attracted increasing attention, as they have been shown to exhibit prophylactic and therapeutic properties in selected infectious diseases in humans. In the present


Complete nucleotide sequence of mouse immunoglobulin mu gene and comparison with other immunoglobulin heavy chain genes.
The results implicate that the nucleotide sequence of the intervening sequence is under selective pressure, possibly to maintain a secondary structure of the nuclear RNA to be spliced, and implicates that the class of the immunoglobulinheavy chain genes diverged after the heavy chain genes established the multi-domain structure.
Exon shuffling generates an immunoglobulin heavy chain gene.
A model suggesting how the phenomenon of switch seen in lymphocytes may occur is presented, suggesting that at least two recombination events occurred to create the gamma 2b gene in MOPC 141.
J genes for heavy chain immunoglobulins of mouse.
A 15,8-kilobase pair fragment of BALB/c mouse liver DNA, cloned in the Charon 4A lambda phage vector system, was shown to contain the mu heavy chain constant region (CHmu) gene for the mouse
DNA sequences mediating class switching in alpha-immunoglobulins.
The lack of homology between this C alpha sequence and sequences reported for the C gamma 1 and C gamma 2b switch sites suggests that heavy chain switching is mediated by class-specific recognition sequences and, presumably, class- specific regulatory mechanisms.
Rearrangements of Immunoglobulin Genes during Differentiation and Evolution
Comparison of nucleotide sequences of CH genes indicates that immunoglobulin genes have scrambled by intervening sequence-mediated domain transfer during their evolution.
